akcesórie - Accessory minerals as indicators of geological processes of Precambrian granitoids formation and their metalogenetic potential (Ukrainian Shield)
Akcesorické minerály ako indikátory geologických procesov formovania granitoidov prekambria a ich metalogenetický potenciál (Ukrajinský štít)
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Broska Igor DrSc.
Annotation:Ukrainian Shield as a unique Precambrian structures situated within European continent include two Proterozoic terraines (megablocks) – Volyn and Ingul megablocks. These megablocks mostly comprize granites formed in different geodynamic settings with wide range of ages and associated ore occurrence and deposits. Ingul megablock (IM) is treated to bee an orogenic region formed as the result of collision between Middle Dnieper granite-greenstone terrain situated on the West and Volyn microcontinent on the East. The merger of both plate and the formation of one-pies collision seam had occurred on the brink of AR3-PR1. The central part of Ingul megablock is treated as fragment of transregional shear zone (Kherson – Smolensk) all structures of which are formed during the the development of this zone. At about 2,1-2,0 billion years, granites of Kirovograd and Novoukrainka types were formed in collision setting. Kirovograd granites are distributed in Central-Wester part of Ingul megablock within regional scale structure known as Ingul sinclinorium. These granites are formed after supracrustal rocks of Ingul-Ingulets series and as a result of prograde ultra metamorphism, occurred in aweakened zone under the drop of pressure. Kirovograd granites are represented by porphyric, equigranular, aplito-pegmatoide, aplite and pegmatite varieties. Geochemical (trace ellement) patterns obtained for these granites indicate that these granites might be related to S-type. Uranium deposit associated with this type of granites can be classified into two genetic types: 1) deposits of potassic-uranium genetic type found in granitic pegmatites similar to that of Rössing type. Among economic ore occurences are Th-REE-U mineralization of Balka Korabelna deposit and three small Th-U deposits (Southern, Kalinovka, Lozovatka) which have been discovered in the south-western part of the Kirovograd continental block; 2) deposits of sodic-uranium genetic type (Novokonstantynivka, Michurinka, Central, Vatutinka, Severynka, Dokuchaevka, Aprelskoe) o are associated with sodic metasomatites (albitites) which are developed after different types of rocks – (gneisses and schists of the Ingul-Ingulets series and pegmatitic granites patially (and genetically?) associated with two-feldspar granites of the Novoukrainka and Kirovograd complexes. Deposits of Li and ore occurrences of Ta, Cs, Rb, Nb, Be, Sn (LCT-type pegmatites) (Polohivka deposit and Stankuvatka ore occurrence) are associated with Li-pegmatites and metasomatites that are considered to be formed at apical part of aplite-pegmatites and granite massifs of Kirovograd type. Volyn (terraine) megablock is the region of tectonic-magmatic activisation which is interpreted to be formedas result of collision between Fennoscandia and Sarmatian segment of West-Europian craton. Intrusive granitoids of Osnytsk types form rock series as a part of Osnytsk-Mikashevychi Vulcano-plutonic association. The Osnytsk-Mikashevychi belt (being the part of large scale Volyn belt) is extending to the North-East of the Central Russian volcanic belt up to the Timan region. This structure border Fennoscandia from Volga-Uralia and Sarmatia along which tectonic movement and magmatic activisation occurred in these crustal blocks. According to isotopic data availiable the granites are thought to be formed from primary melt of mantlle origin. The final stage of major orogenic events occurred within Volyn megablock were manifesyed by the intrusion of Korosten pluton in anorogenic setting. The intrusion was preceded by unstable subplatform regime in the peripheral part of the Osnytsk orogenic belt. It formation was finished at 1,8-1,74 billion years ago. Korosten pluton is complex polyphase intrusive of anorthosite-rapakivi-granite formation (ARGF). The intrusion of Korosten type is the oldest among widely known world occurrence of ARGF. In addition, it is the largest pluton ARGF of West-European craton as well as among all plutons found in Ukrainian Shield. About 75% of total area of Korosten pluton is comprized by rapakivi and rapakivi-like granites. Other 25 % is covered by the basic and hybrid type rocks. According to geochemical features these granites should be related to granites of A-type. This project is aimed at intensification of the scientific cooperation between scientists of the Geological institution of Slovakia Academy of Sciences and National academy of Sciences of Ukraine. Sharing the scientific experience can help to solve a scientific fundamental problem and to find general features of distribution mineralization and economic ore occurrences/deposits both within territories of Slovakia and Ukraine

TIDES - Time Dependent Seismology
Časovo závislá seizmológia
Program: COST
Project leader: prof. RNDr. Moczo Peter DrSc.
Annotation:Seismology is learning to use the full-length records of seismic events and background ambient noise to go beyond still-life snapshots of the interior of the Earth, and look into time-dependent changes of its properties. Data availability has grown dramatically with the expansion of seismographic networks and data centers, and new efforts are bringing in highly promising, unconventional records of earth vibrations, so as to build prospects of more detailed and accurate analyses. New modelling techniques hold promise for deeper exploitation of information contained in the data. COST Action TIDES (TIme DEpendent Seismology) aims at structuring the EU seismological community to enable development of data-intensive, time-dependent techniques for monitoring Earth active processes (e.g., earthquakes, volcanic eruptions, landslides, glacial earthquakes) as well as oil/gas reservoirs. TIDES will network European laboratories in Academia and Industry with complementary skills and will organise a series of workshops and advanced schools to train the next generation of scientists. TIDES will facilitate the exploitation of massive data sets collected by European observational infrastructures - coordinated through the ESFRI EPOS - through the use of high-performance computing facilities. TIDES will strengthen Europe's role in a critical field for natural hazards and natural resource management.

Electrical conductivity and geological structure in the West Carpathians and its transition to the Bohemian Massif
Elektrická vodivost a geologická stavba Západných Karpát a ich prechodu k Českému masívu
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Bezák Vladimír CSc.
Annotation:The aim of the project is to interpret the structure of the Earth’s crust of the West Carpathians in the area of southern and south-eastern Slovakia by jointly modelling geophysical and tectonic data in the region. Available seismic, magnetic and gravity data will be modelled jointly with broad-band magnetotelluric data, which have been either made available from previous experiments or will be partly collected by targeted experiments within this project. Owing to its sensitivity to spatially localized accumulations of highly conductive fractions, either fluids or electronic conductors related to tectonic disturbances in the crust, the electrical conductivity effectively complements geophysical images of the Earth’s crust by providing estimates on the spatial distribution of significant tectonic zones at great depths. The obtained synthetic physical models will be utilized for the interpretation of deep tectonic zones and of the deep geological structure of the Earth’s crust within the frame of the General geological map of the Slovak Republic 1:200.000.

Continental Cris - CONTINENTAL CRISES OF THE JURASSIC: MAJOR EXTINCTION EVENTS AND ENVIRONMENTAL CHANGES WITHIN LACUSTRINE ECOSYSTEMS
Jurské kontinentálne krízy: hlavné vymieracie udalosti a zmeny prostredia v lakustrinných ekosystémoch
Program: UNESCO
Project leader: doc. RNDr. Michalík Jozef DrSc.
Annotation:This IGCP project will more specifically focus on the Jurassic Period, starting with the mass extinction event that occurred 202 million years ago just prior to the Triassic-Jurassic boundary, through the Toarican anoxic event 183 million year ago and finally covering the Jurassic-Cretaceous boundary at 145 million years ago where major lake systems expanded over continents. The Jurassic and Cretaceous constitute the ‘age of the dinosaurs’, a time interval with green house conditions when perennially warm vegetation types extended into the high-latitudes of Scandinavia, Greenland, China and in fact to the poles. The research focuses on major events and their relation to climatic and environmental changes within these ancient lacustrine ecosystems, and the correlation with the marine realm. Additionally, our project has a strong component of applied Earth sciences because these sediments host significant fossil fuel resources, including coal, gas and petroleum that are stored in the sub-surface. Organic-rich shales and limestones are a prominent feature of most of our target areas. Future developments prosperous society depends on access to energy resources, the negative effects of burned fossil fuels can be mitigated by CO2 sequestration, where carbon dioxide is removed from the flue gas and stored in underground reservoirs.

Kriedové zmeny m - Climate-environmental deteriorations during Greenhouse phases: Causes and consequences of short-term Cretaceous sea-level changes
Klimaticko-environmentalne zhoršenie počas skleníkových fáz: príčiny a následky krátkodobých kriedových zmien morskej hladiny
Program: UNESCO
Project leader: doc. RNDr. Michalík Jozef DrSc.
Annotation:The recent rise in sea-level in response to increasing levels of atmospheric greenhouse gases and the associated global warming is a primary concern for society. Evidence from Earth’s history indicate that glacial-interglacial and some more ancient sea-level changes occurred at rates an order of magnitude or more higher than that observed at present. To predict future sea-levels we need a better understanding of the record of past sea-level change. In contrast to glacial eustasy controlled mainly by waxing and waning of continental ice sheets, short-time sea-level changes during major greenhouse episodes of the earth history are known but still poorly understood. The global versus regional correlation and extend, their causes, and consequences of these sea-level changes are strongly debated. The proposed project addresses correlation, causes and consequences of significant short-term, i.e. kyr to 100s of kyr, sea-level changes during the last major greenhouse episode of earth history, the Cretaceous. The long-term sea-level record, i.e. 1st to 2nd order cycles occurring over millions to tens of millions of years, is controlled by the internal dynamic history of the Earth. The changing rates of ocean crust production led first to long-term sea-level rise, high stands, and then decline during Cretaceous times. However, superposed shorter-term, 3rd to 4th order (kyr to 100s of kyr), sea level changes are recorded in Cretaceous sedimentary sequences. The mechanisms for these are controversial and include brief glacial episodes, storage and release of groundwater, regional tectonism and mantle-induced processes. Recent refinements of the geological time scale using new radiometric dates and numerical calibration of bio-zonations, carbon and strontium isotope curves, paleomagnetic reversals, and astronomically calibrated time scales have made major advances for the Cretaceous. Major international efforts such as EARTHTIME, EARTHTIME-EU and GTSnext programs are improving the Cretaceous time scale to yield a resolution comparable to that of younger Earth history. It is now for the first time possible to correlate and date short-term Cretaceous sea-level records with a resolution appropriate for their detailed analysis. This project will investigate mid- to Late Cretaceous (120 Ma – 66 Ma) sea-level cycles in detail in order to differentiate and quantify both short- and long-term records within the new high-resolution absolute time scale based on orbital cyclicity. The time interval for study begins with the first major oceanic anoxic event (OAE 1a) and terminates at the end of the Cretaceous. It includes the time of super-greenhouse conditions, the major oceanic anoxic events, the Cretaceous Thermal Maximum and the subsequent cooling to ordinary greenhouse conditions. The first major goal is to correlate high-resolution sea-level records from globally distributed sedimentary archives to the new, high-resolution absolute time scale, using sea-water isotope curves and orbital (405, 100 kyr eccentricity) cycles. This will resolve the question whether the observed short-term sea-level changes are regional (tectonic) or global (eustatic) and determine their possible relation to climate cycles. The second goal will be the calculation of rates of sea-level change during the Cretaceous greenhouse episode. Rates of geologically short-term sea-level change on a warm Earth will help to better evaluate recent global change and to assess the role of feedback mechanisms, i.e. thermal expansion/contraction of seawater, subsidence due to loading by water, changing vegetation of the Earth System. The third goal will be to investigate the relation of sea-level highs and lows to ocean anoxia and oxidation events, represented by black shales and oceanic red beds, and to evaluate the evidence for ephemeral glacial episodes or other climate events. Multi-record and multi-proxy studies will provide a high-resolution scenario for entire sea-level cycles and allow development of quantitative models for sea-level changes in greenhouse episodes

A 250 year history of human impacts on a landscape of the Banská Štiavnica mining territory: palaeolimnological reconstruction using biotic and abiotic indicators from lake sediments
Antropické zmeny prostredia v banskoštiavnickej banskej oblasti počas posledných 250 rokov: paleolimnologická rekonštrukcia s využitím biologických a abiotických indikátorov zo sedimentov vodných nádrží.
Program: VEGA
Project leader: Dr. Kyška-Pipík Radovan PhD.
Annotation:The Banská Štiavnica region belonged to the most important mining regions in Europe since the Middle Ages. Due to mining, the economic development of this area has increased, on the other hand, mining has left a legacy of residues and waste from ore processing. Many of these structures, e.g. reservoirs, have become a part of the landscape and, interestingly, made it even more attractive. That is likely the reason why impact of the mining activities has yet been evaluated as a geomorphological factor rather than an environmental issue. In contrast to previous studies focusing on the current landscape and ecosystems, the proposed project will study the extent and intensity of human impacts for the last ~250 years using multi-proxy approach. Except for evaluating environmental contamination by mining waste and its potential risk to organisms and humans, the project represents a unique opportunity to observe the dynamics and timing of processes leading to the current status of terrestrial and aquatic ecosystems.

Atmospheric processes and tropospheric ozone in the mountain environment
Atmosférické procesy a troposférický ozón v horskom prostredí
Program: VEGA
Project leader: Ing. Bičárová Svetlana PhD.
Annotation:Complex terrain of the High Tatra Mts is characterised by variable meteorological and climatic conditions. Driving forces of atmospheric processes in system atmosphere-soil-vegetation are solar radiation and energy balance of earth surface. Serious problem of mountainous regions is long-range transport of secondary air pollution, especially dry deposition of ground-level ozone (O3) and wet depositon of acidifying components (S, N, H+). Recent research of O3 impact on forests requires detailed information about the physical and chemical processes associated with O3 formation (photochemical potential of UV radiation) and transport of O3 from the atmosphere to the earth surface (dry deposition). The aim of this project is to study the variability of solar and UV photochemically active radiation; to evaluate the extent of acidification or eutrophication of forest soils and to estimate the phytotoxic O3 potential for typical forest species in the High Tatras region.

DEPOVYT - Deglaciation and postglacial climatic evolution recorded in the lake deposits of the High Tatra Mountains
Deglaciácia a postglaciálny klimatický vývoj Vysokých Tatier zaznamenaný v jazerných sedimentoch
Program: APVV
Project leader: Dr. Kyška-Pipík Radovan PhD.
Annotation:The historical and meteorological climate records are too short to appreciate a global average temperature increase since 1990. Therefore it is necessary to search information about environmental changes in the past for reflections on future climate and environmental change and the mechanisms of natural climate variability. One of the most intensively studied geological period in palaeoclimatology is the transition between the last glacial maximum (LGM) and the Holocene when the average annual temperature of the atmosphere increased by 5°C and greatly affected the Earth's ecosystems. LGM resulted in the formation of mountain glacier in the High Tatras, which after its maximum extension at around 23 ka retreated and disappeared 8330 BP. Knowledge about the timing of the deglaciation and the subsequent ecological changes remain limited despite 150 years of glaciological research in the High Tatras. The main project aim is study of deglaciation in alpine zone after LGM with respect to topography, altitude and orientation to north-south gradient. It will study a transition from glacial to post-glacial sedimentation and environmental changes in limnic sediments after the glacier retreat. To achieve the research objectives, the selected lakes cover a whole territory of the Slovak part of the High Tatras which has not yet been studied on the proposed scale. Sedimentary infill will be studied by analytical methods that have not yet been used in postglacial research in the Western Carpathians. A unique database of the High Tatras lakes infill will be built.

Origin of the Evate phosphate deposit, Mozambique
Genéza fosfátového ložiska Evale v Mozambiku
Program: VEGA
Project leader: doc. RNDr. Hurai Vratislav DrSc.
Annotation:The project is aimed to provide mineralogical, geochemical and genetic characteristics of the Evate deposit in Mozambique, which is one of the largest phosphate deposits of Africa, with estimated reserves of 155 millions of metric tons of ore with 9.3 % of P2O5 calculated to the depth of 100 m from the recent surface. The deposit is intended to supply with apatite the fertilizer complex to be built in the nearby coastal district of Nacala-a-Velha. In spite of the prepared exploitation, the mineralogy of the deposit is poorly elucidated and its origin remains controversial. Recent models include metamorphogenic or magmatogenic origins linked with Precambrian alkalic intrusions. Magmatic deposits of similar types (e.g. Kovdor, Kola), however, serve primarily as a source of rare earth elements and rare metals bound in apatite and specific minerals. Detailed mineralogy as well as genetic information have a profound importance for the exploitation, beneficiation strategy and economic assessment of the deposit.

Geophysical model of the lithosphere of the Western Carpathians
Geofyzikálny model litosféry Západných Karpát
Program: VEGA
Project leader: RNDr. Vajda Peter PhD.
Annotation:Geophysical model of the lithosphere of the Western Carpathians will be based on the results obtained by 2D and 3D interpretation of gravity and thermal field of the Earth. In the frame of interpretation the modern, world-wide accepted, gravimetric and geothermic methods will be applied. These methods will also use the newest results of the other geophysical fields (mainly seismic), geology and geodesy. The resultant 2D and 3D lithospheric models will represent the utilization of all knowledge on the deep-seated structure of the Western Carpathian lithosphere on the basis of own interpretation of gravity and thermal field. Based on these models a new geophysical model of the lithosphere of the Western Carpathians will be constructed, which will extend our present knowledge on the recent structure, composition and tectonics of the lithosphere in the Western Carpathians. The model will be also a basis for tectonic reconstruction of the space distribution of the tectonic elements of the Western Carpathians.

Annotation:Project is focused at geochemistry and age relations of the Pre-Alpine dike igneous rocks in the Western Carpathians. Origin, time and spatial relations of the dike igneous rocks are going to be solved, based on the geochemical characteristics. Studied rock types will be felsic granitic porphyries, intermediate to basic rocks (kersantitesand spessartites). The main goal of study of these rocks is their age and genetic relations to host rock(crystalline complexes – granites mainly). The last studied rock types are alkaline lamprophyres. Again, their age and genetic relations to their host rock will be defined in the different tectonic units. The modern laboratory methods will be used for interpretations (Rb, Sr, Sm, Nd isotopes) and Ar/Ar to U/Th/Pb dating of apatite, monazite. These data will be obtained by cooperation with foreign institutions (Polish Academy of Science, Krakow, Trinity College Dublin, Kyoto University, Okayama University of Science, University Lund).

ID-EFFECTS - Identification and characterization of a potencial of site effects using robust numerical modelling of equarthquake ground motion
Identifikácia a charakterizácia potenciálu lokálnych efektov pomocou robustného numerického modelovania seizmického pohybu
Program: APVV
Project leader: Mgr. Kristeková Miriam PhD.
Annotation:The last two decades tragically and dramatically demonstrated capability of even relatively weak earthquakes to cause human losses and damage. The key reasons for this are buildings which are not designed/reinforced to withstand earthquake ground motion (EGM), increasing vulnerability due to technological complexity of densely populated areas, and anomalous earthquake ground motion due to local surface geological conditions. Seismic wave interference and resonant phenomena in sediment-filled basins and valleys can produce anomalously large EGM and cause the so called “site effects”. Site effects pose a potential threat also for important nuclear and industrial facilities. It is therefore important to identify and characterize a potential of site effects at sites of interest. In the absence of sufficient earthquake recordings one possible approach is to numerically simulate EGM. We assume that a verified and validated computationally efficient numerical method makes it possible to obtain synthetic “data” that could approximately substitute missing measured data for which we would have to wait for a too long time. A systematic investigation of EGM characteristics in a significant/representative set of realistic models of local conditions can lead to identification of key EGM characteristics and key structural parameters responsible for site effects, and consequently to identification and characterization of a potential of site effects in the set of considered local surface conditions.

Integrated sedimentological study of the Paleogene formations of the Central Western Carpathians: a reconstruction of the depositional paleoenvironments in relation to tectogenetic processes, subsidence history of the basin and changing climate regimes
Integrovaný sedimentologický výskumu paleogénnych súvrství Centrálnych Západných Karpát: rekonštrukcia depozičných paleoprostredí vo vzťahu k tektogenetickým procesom, subsidenčnej histórii panvy a meniacim sa klimatickým režimom.
Program: VEGA
Project leader: Mgr. Starek Dušan PhD.
Annotation:The goal of proposed project is the implementation of integrated sedimentological research of the Paleogene Fm. of the Central Western Carpathians. Sedimentary formations of the Subtatric Group originated in different depositional palaeoenvironments evolving during sequence-stratigraphic evolution of the basin and their nature was in direct relation to the changing climate, tectogene processes and subsidence history of the basin. Implementation of detailed facies analysis inclusive sedimentology, petrography and palaeontology research allow to define main depositional palaeoenvironments, their lateral and vertical development as well as their genetic relations. The results will contribute to the interpretation of the basin fill architecture and its palaeoenviromental developments in relation to changing system tract during sequence - stratigraphic evolution of the basin. The acquired knowledge will have a wider use in the reconstruction of paleogeography and tectogenesis of the Carpathian Paleogene basins.

Complex model of base and precious metal mineralisation at the Rozália mine in Hodruša - Hámre
Komplexný model polymetalicko-drahokamovej mineralizácie na Rozálii bani v Hodruši - Hámroch
Program: APVV
Project leader: RNDr. Lexa Jaroslav CSc.
Annotation:The project deals with the only ore deposit actively mined in Slovakia that is exceptional by richness of ore and its structural position on subhorizontal veins in center of the Štiavnica stratovolcano caldera. Epithermal Pb-Zn- Au-Ag vein deposit at Rozália mine was studied in detail just in its western part, while for its eastern part which is being intensively mined already since 2008, there are missing basic data about structural position, mineralogy and alteration. Genesis of the deposit is neither sufficiently solved. The absence of this information causes problems in exploration for further occurrences of this type of mineralisation in the district and in processing of ore. The creation of a complex model of mineralisation, including 3D modelling of mining works, geology and distribution of useful metals at the deposit in GIS, will significantly contribute to formulation of genetic model and resource assessment and it will result in more effective exploration and mining activities at the deposit. Genetic model of this exceptional deposit will contribute to general understanding of genesis of epithermal systems.

Korelačné eventy globálnej stratigrafie a paleoprostredia v kriedových a paleogénnych súvrstviach Západných Karpát: biotické, sedimentárne a geochemické indikátory.
Program: VEGA
Project leader: doc. RNDr. Soták Ján DrSc.
Annotation:The project is focused on two dissimilar gological periods, in which the fundamental changes of Earth?s global systems took place. These changes disturbed the conditions of thermal stability of the Cretaceous period and culminated by the biotic crisis on K/T boundary (65.5 Ma), which was folloved by perturbations with enormous uprise of temperature (55 Ma), climatic optimum (40 Ma) a finally with the Late Eocene climatic cooling (33.5 Ma). Therefore, the project goals are intended in identification and stratigraphic dating of these global events in sedimentary formations of the Western Carpathians. Their records will be analysed in term of bioproductivity, paleotemperatures and nutrients, oxygen concentration, stress indicators, stable isotopes, volcanic and meteoric products. Such data allow to interpret the events of extinction and phylogenesis of new taxa, climatic conditions, anoxic events, indices of eutrophization, eustatic changes, sedimentary environments, syngenetic volcanisms and impact events.

Mesozoic changes of climate, sedimentation, palaeooceanologic proxies, environments and communities of marine organisms
Mezozoické zmeny podnebia, sedimentácie, paleooceánologických faktorov, prostredí a spoločnstiev morských organizmov.
Program: VEGA
Project leader: doc. RNDr. Michalík Jozef DrSc.
Annotation:The project deals with the interpretation of complex geological record of significant changes in the Mesozoic evolution of the Western Carpathians in terms of paleoclimate, paleooceanology, paleogeography and palaeoecology aspects. Detailed sedimentary research includes cyclostratigraphy, sequence stratigraphy, microfacies, geochemistry and magnetostratigraphical analysis and study of communities of marine organisms. Attention is paid mainly on quantitative and qualitative analysis of planktonic microfossils in particular communities and on residual organic matter. The object of the study will be applied on coherent profiles through sections with prominent lithological breaks indicating periods of turnovers between different environmental regimes in sedimentary basins. To determine the age and spatial dependence of marker horizons, biostratigraphical analysis and astrochronological correlation of sedimentary cycles will be also used.

Mineralogy and genesis of economically important types of gold mineralization in the Central Slovakia Volcanic Field
Mineralógia a genéza ekonomicky významných typov mineralizácií zlata v stredoslovenských neovulkanitoch
Program: VEGA
Project leader: RNDr. Lexa Jaroslav CSc.
Annotation:This project deals with characterisation of two most important types of precious metal mineralisation in Slovakia that have a real economic importance. Completion of their current level of knowledge in terms of mineralogy and genesis can significantly help in exploration and mining of these ores. Epithermal vein Au-Ag deposit Rozália mine was studied in detail in its western part, while for its eastern part that is intensively mined since 2008, mineralogical data are missing and its genesis is not satisfactorily clear. The absence of this information causes problems with processing of ores and prospecting for this type of ore in this district. Porphyry gold mineralisation is a new type of Au ore in Western Carpathians that proved to be a very specific type of deposit even in world comparison. The study of this mineralisation has a potential to significantly improve the knowledge of these rare magmatic-hydrothermal systems, which can help to make their exploration more effective also elsewhere in the world.

Project leader: RNDr. Siman Pavol PhD.
Annotation: Project deals with fluid-alteration processes in crust-mantle prism rocks exposed in alpidic orogene of the Western Carpathians, eastern Alps and northern Turkey. These processes are related to important magmatic and metamorphic events which we studied in previous projects. Now we are focussing on fluid-rock interaction zones, the genesis of which has not yet been investigated: i) in subduction-accretionary wedges blueschists, eclogites and metaultramafics, ii) in lower crust orthogneisses, granites, metabasites and metaultramafics, iii) in skarns and iv) in lamprophyres and mantle xenoliths. These processes represent a fluid-rock interaction at the different lithosphere levels. The emphasis will be given to the newly-found mineral parageneses and individual phases, which can be basis for an updated petrologic model of crust-mantle interaction. Detailed mineralogical-petrological investigation will be performed on the altered rocks mineral associations, which are the main indicators of the lithosphere fluid regime. Modern microscopic, electron-optic, rtg diffraction and spectroscopic methods will be used for determination of the alteration zones mineral and rock chemical compositions. Thermodynamic modelling and geothermobarometry will be applied for estimation alteration reactions P-T-X conditions. Chosen radiogenic and stable isotopes, and isotopic ages of alteration products will be determined. Potential sources of fluids will be defined accordingly. The lower-temperature alterations will be simulated in an autoclave; for verifying the higher-temperature and higher-pressure alteration conditions an access to special experimental laboratories abroad is required in framework of international co-operation. Model schemes of hydration-alteration processes will be proposed in microscale, with the aim to use them for geodynamic interpretation of an orogene accretionary wedge fluid regime.

CRITHON3D - Multi-dimensional integrated geophysical-petrological modelling of the crust, and uppermost mantle for central Europe region by structural joint inversion
Multi-dimenzionálne integrované geofyzikálno-petrologické modelovanie kôry a vrchného plášťa v regióne strednej Európy pomocou štrukturálnej joint inverzie - CRITHON3D
Program: SASPRO
Project leader: RNDr. Vozár Ján PhD.
Annotation:Geophysical research, particularly using geoelectrical methods, significantly contributes to understanding and exploring processes related to strategic energy and mineral resources. The combination of different geophysical methods in a single inversion scheme reduces the non-uniqueness of inversion problems and the resulting models. Integrated geophysical and petrological modelling, together with inverse problems, represents some of the most interesting research topics for geophysical studies. In this project a petrologically driven approach with LitMod3D package, which models geophysical observables, constrained by topographic height and heat flow, will be extended by structurally coupled crustal model created by 3D joint inversion framework code for gravity, seismic and magnetotelluric data with the new name LitMod3Dic. The original LitMod package derives realistic temperature and pressure distributions within the upper mantle and characterizes mineral assemblages of given bulk chemical compositions as well as water content, which will allow us to define a bulk geophysical model of the upper mantle to derive corresponding predicted geophysical observables. The implementation of crustal inversion scheme will be done in two steps: a) the MT inversion code with geoelectrical crustal model will be included, because the MT 3D inversion code is most time consuming for numerical calculation and the necessary modifications of the MT inversion code will be essential; b) the 3D joint inversion framework approach will be included to add coupled crustal density and seismic velocities models. The final modified code LitMod3Dic will be used to undertake a multi-dimensional, petrologically-driven approach of combining MT, gravity and seismic data in inversion modelling of the upper-most mantle in the Carpatho-Pannonian region, followed by studies which will focus on the mapping of Neo-vulcanites and sub-basaltic crustal structures and thermal parameters in eastern and central Slovakia.

Multiproxy analysis of limnic profundal deposits: cyclicity and variability of the environment in Late Miocene of the Central Paratethys
Multiproxy analýza limnických profundálnych sedimentov: cyklicita a variabilita prostredia vo vrchnom miocéne Centrálnej Paratetýdy
Program: VEGA
Project leader: Dr. Kyška-Pipík Radovan PhD.
Annotation:The Miocene subtropical climate in the Central Paratethys culminated in the Middle Miocene climatic optimum (MMCO), followed by periods of warming and cooling (from MMCO to 8.5 Ma.) showing a gradual cooling trend. Factors of climate change could be the paleogeographic changes as well cyclicity of solar activity. Freshwater, profundal limnic sediments of the Turiec Basin with rich fossil microflora and microfauna deposited in the period from 8.0 to 6.0 Ma are an opportunity to obtain data on cyclicity and variability of the environment in that period. To achieve the objectives, a multi-proxy approach will be applied on profundal deposits. Heavy metal concentrations, natural gamma-radiation of the deposits, paleobiological and geochemical analyzes will be used as proxy data. The magnetostratigraphic data will permit a correlation with international stratigraphic scale and they allow calculating a model on a sedimentation rate, analysis of time series and detection of changes in variability and cyclicity.

Numerical solution of the kinematic problem for geomagnetic secular variations
Numerické riešenie kinematickej úlohy pre sekulárne variácie geomagnetického poľa
Program: VEGA
Project leader: RNDr. Marsenić Alexandra PhD.
Annotation:Hydromagnetic processes taking place in Earth's liquid core act as a source of geomagnetic secular variations. The key region, where the field is advected by large-scale flows and modified otherwise is the one beneath the surface of the core. Core dynamics is manifested by changes of intensity and position of the magnetic field's characteristics measured on the Earth's surface. One of its signs is westward drift of the non-dipole part of the geomagnetic field which directly shows advection of the field by flows in the core. Reversed flux patches identified at the core-mantle boundary are part of it. On the Earth's surface they appear as anomalous regions of low intensity. Analytic kinematic study of verical geomagnetic variation [10] explains them as a consequence of cooperation of 3-dimensional convection in the diffusionless main volume and resistive effects in the hydromagnetic boundary layer at the mantle. Numerical solution of the problem may help to better understand the complex dynamics of the core.

Oblastné stratotypy pre genetické, vekové a paleoenvironmentálne charakteristiky sedimentárnych paniev Západných Karpát
Program: APVV
Project leader: doc. RNDr. Soták Ján DrSc.
Annotation:The project is focused to the study of stratotype sections, which provide a high-qaulity geological record for calibration of geological time scale and sedimentary archives of paleoenvironmental changes. The basic research will include the codification of the informal stratigraphic units, redefinition of historical stratotypes, classification of litho-, bio- and geochronological units, regional and interregional correlation of the units, etc. The stratotype study will be followed by multidisciplinary approach and application of the high-resolution methods, which provides the best-class data for time table calibration and identification of paleoenvironmental changes. Selection of stratotype profiles will be oriented to boundary strata, in which is possible to determine the extinction events and morphogenetic changes of the organisms, climatic and ecologic changes of paleoenvironments, sedimentary and hydrographical regimes of the basins, orbital and eustatic changes, depositional changes, paleomagnetic changes, records of impact events and syngenetic volcanisms, etc. This research provides a new informations for international decision of the Slovakian stratotypes and new potential statotypes for the Mesozoic and Cenozoic formations of the Western Carpathians. The project resulted to monographic publication of the Slovakian stratotypes, representing the standarts of time scale and records of paleoenvironmental changes.

Annotation:Detection and monitoring of underground cavities belongs among important environmental risk assessments, on the other hand it is the aim of the research in archaeological and historical scientific studies. Geophysical (microgravimetry, ERT, GPR) and geodetic methods (LiDAR, InSAR, UAV photogrammetry) manifest a useful tool for underground cavities detection and monitoring. Aim of the proposed project is the study of their properties in methodical and also application area. By means of numerical modelling of cavities existence and development in geophysical fields we can obtain valuable information and use them in successful detection and monitoring of them in practice. Planned analysis of studied methods properties in the frame of practical use we would like to realize in localities in selected mining areas - historical and present ones (Horná Nitra and Banská Štiavnica sites) and during historical research of known cultural monuments (church of St. Martin in Bratislava and church of St. Nicholas in Trnava).

Annotation:The tectonic situation in the Malé Karpaty (Little Carpathians Mts.) area is complex and this source zone belongs to the most active parts of the Slovak territory. The main purpose of this project is an improvement of the knowledge of seismic regime of investigated area. Data obtained within the project are very important for seismic hazard studies and necessity of the complex seismic hazard evaluation of this area is increased by presence of close nuclear power plant Jaslovské Bohunice. To achieve the main goal of the project we plan to increase the precision of earthquake hypocenter location by using double difference HypoDD method, to improve focal mechanism solutions of local events (for new events and those already analyzed). We plan to use micro-arrays measurements for monitoring and locating weak events and identification of active faults and to use seismic noise measurements for improvement of knowledge of a seismic model in the area.

Stability and retrograde alterations of accessory minerals from the rocks of collisional orogenic zones
Stabilita a retrogádne premeny akcesorických minerálov v horninách kolíznych orogénnych zón
Program: VEGA
Project leader: RNDr. Petrík Igor DrSc.
Annotation:The geological evolution of orogenic zones (in polymetamorphic terrains as in Western Carpathians) involves burial, metamorphism, magmatism, post-magmatic transformations, retrogression and subsequent metamorphism. Rocks adapt (re-equilibrate) to new conditions via reactions among their minerals. Here, accessory minerals (monazite, allanite, ilmenite, apatite, magnetite, ilmenite, rutile, kyanite, graphite, diamond) are very informative when reacting with rock-forming minerals (garnet, biotite, plagioclase, muscovite) by changing composition, or formation of new assemblages. The transformations of accessories (in addition to rock-forming) are extremely useful for derivation of pressure, temperature and fluid compositions using equilibrium reactions among them. Because theretrogression of UHP rocks is almost inevitable, often only the accessory minerals maintain information on peak conditions. The essence of the project is the study of transformations of these minerals and their use for geodynamic interpretations

Stabilita akcesorických minerálov a mobilita vzácnych litofilných prvkov a C v horninách kolíznych orogénnych zón: prográdne a retrográdne premeny
Program: APVV
Project leader: RNDr. Petrík Igor DrSc.
Annotation: Project will deal with stabilities and transformations of accessory minerals (with emphasis to REE, Nb, Ta, C) from granitic and metamorphic rock in the process of subduction and exhumation. By the identification of primary and secondary phases and by quantification of the transformations (reactions among the phases) it is possible to derive P-T-X parameters of metamorphism and suggest a tectonic interpretation. Complex transformations of the accessories involve also rock-forming minerals which enables the calculation of reactions. In detail there will be studied REE minerals (allanite, monazite, and products of their alterations) along with apatite, Nb-Ta phases, tourmaline, Fe-Ti oxides according to the rock type. The study of monazite (non)stability has direct consequences for the age interpretation of complex grains. A special attention is given to transformation graphite-diamond in ultrahigh-pressure rocks. For successful solving the project goals proper terrains are suggested where, besides polymetamorphic rocks of the Western Carpathians, ultrahigh-pressure rocks of the Pohorje, Caledonides, and Rhodope Mts. are well developed. The project has a character of basic research but some of expected results are applicable to “nuclear ceramics” suggested for as materials for deposits of radioactive waste because knowledge of geochemical mobility during alteration is important for post-depositional risk estimates.

Statistical analysis of long-term radon time series from Slovakia
Štatistická analýza dlhodobých časových radov kontinuálne meranej objemovej aktivity radónu na Slovensku
Program: VEGA
Project leader: RNDr. Smetanová Iveta PhD.
Annotation:The project addresses the unsolved issue of the drivers of the variation of radon. High resolution monitoring of 222Rn activity concentration performed in different natural subsurface environments (boreholes, gallery, caves) in Slovakia yielded long time series. The temporal variation of radon, which contains periodic and non-periodic signals, spans variation of annual to diurnal scale. Time series of radon and environmental conditions will be systematically analyzed in the time and frequency domains. The derived statistical characteristics of the radon variation will be evaluated against those of the associated environmental parameters, to assess the eventual influence of the latter on radon in the gas phase. In addition, the characteristics of the radon time series will be evaluated in the light of recent conjectures attributing the influence of a component of solar irradiation on the periodic radon signals. The outcome of the investigation pertains also to the issue of the radon hazard to a human being.

Timing, extent and depth of Late Pleistocene epizodic thawing of permafrost inferred from cave paleoclimatic records of Slovakia.
Vek, rozsah a hĺbka epizodického topenia permafrostu počas neskorého pleistocénu – údaje z jaskynných klimatických archívov Slovenska.
Program: VEGA
Project leader: Mgr. Milovský Rastislav PhD.
Annotation:Paleoclimate studies based on high-resolution geochemical records (deep sea and ice cores, corals, speleothems) are increasingly important in present days of rapid climate change. In recent years the novel paleoclimatic indicator was discovered – the cryogenic cave carbonate. Its use is however not straightforward and demands deep understanding of its formation – thus it is not implemented as systematically as other archives. Nevertheless, an extra benefit is its ability to record thaw of permafrost and even its depth. This strongly favours the CCC to be subject of global climate studies, as the clathrate breakdown and methane escape from thawing permafrost is nowadays considered as an important trigger of global warmings. Aim of the project is thorough understanding of mechanisms and timing of cave glaciations relative to global climate oscillations, with endeavour to turn CCC to a robust tool for mapping extent and thickness of permafrost in different periods of the Weichselian glacial.

High-pressure metamorphism in the crystalline complexes of the Western Carpathians
Vysokotlaková metamorfóza v kryštaliniku Západných Karpát
Program: VEGA
Project leader: RNDr. Janák Marian DrSc.
Annotation:Eclogite facies rocks are a westige of deep crustal subduction during the orogenic cycle. The aim of a proposed project is study of high-presure, eclogite facies rocks in the crystalline complexes of the Western Carpathians. Identification of eclogite facies mineral assemblages and timing of metamorphism can be achieved using modern mineralogical, petrological and geochronological methods. In addition to the presence of eclogites, it is important to investigate the host rocks of eclogites, such as kyanite-bearing paragneisses and orthogneisses as well as metaultramafic rocks. It seems to be obvious that also these rocks, closely associated with metabasites, underwent high-pressure metamorphism. P-T conditions of metamorphism can be obtained from thermobarometric calculations and phase equilibria modeling. Timing of metamorphism and exhumation can be constrained by geochronological methods using different geochronometers. The reconstruction of metamorphic P-T-t paths followed by eclogite facies rocks can decipher the mode and timing of subduction and exhumation. This can provide a fundamental framework for elucidating the overall geodynamic evolution of the orogenic belt with implications for the geological history of the Western Carpathians.

Evolution of monogentic rhyolite volcanoes
Vývoj monogenetických ryolitových vulkánov
Program: VEGA
Project leader: RNDr. Lexa Jaroslav CSc.
Annotation:Rhyolite volcanoes represent a substantial part of Tertiary volcanites in Carpathians and Pannonian basin. They often host epithermal and VMS mineralizations and a suite of industrial mineral and stone deposits (perlites, silicites, clays, bentonites, zeolites, pumice and stone/aggregate). Explosive eruptions of rhyolites and pyroclastic flows associated with a growth of extrusive domes represent also a serious hazard in areas of active volcanism. A greater knowledge on processes and products of rhyolite volcanism is desirable. Also for the rhyolite volcanism there is characteristic formation of monogenetic volcanic fields. The project aims at paleovolcanic reconstruction of the Tertiary monogenetic rhyolite volcanoes in Slovakia and northern Hungary, characteristics of their eruption mechanism, their evolution in time and relationship among their evolution and form on one side and basement structure and magmatic source on the other side. We shall compile a generalized model of their evolution.

Tracing changes in seawater temperature during the end-Triassic mass extinction and during the Early Jurassic in the western Tethys (Western Carpathians and Eastern Alps)
Zmeny v teplote morskej vody počas masového vymierania na konci triasu a počas ranej jury (Západné Karpaty a Východné Alpy)
Program: VEGA
Project leader: Mgr. Tomašových Adam PhD.
Annotation:Distribution, diversification, and extinction of marine organisms is fundamentally determined by factors that directly or indirectly affect their physiological processes. Presently, it is hypothesized that significant changes in temperature and seawater chemistry and changes in water-mass stratification triggered the end-Triassic mass extinction of marine invertebrates. Empirical testing of such hypotheses, however, requires generation of temporally- and spatially-explicit databases with paleotemperature estimates derived from geochemical and paleoecological proxies. Our goal is to determine temperature means, minima, and maxima, and onshore-offshore gradients in temperature during the Rhaetian and Early Jurassic (Hettangian-Pleinsbachian) in the NW Tethys (Western Carpathians and Eastern Alps) on the basis of brachiopods, bivalves, and foraminifers, using paleoecological analyses, stable isotopes, and Mg/Ca ratio, and to assess extinction selectivity in respect to population abundance and body size.
