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

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

Program: Medziakademická dohoda (MAD)
Project leader: doc. RNDr. Michalík Jozef DrSc.
Annotation:Recent studies in both countries (Slovakia and Bulgaria – Michalik et al., 2016; Lakova & Petrova, 2013; Grabowski et al., 2016; Stoykova et al., submitted) have demonstrated the availability of suitable geological object for detailed study – well-exposed continuous sedimentary successions across the JKB interval. Our goal aims at complex investigation of two geological locations, comprising the JKB interval – one in Slovakia and one in Bulgaria. The direct integration of regional geology, lithofacies studies, calpionellid and nannofossil biostratigraphy, sequence stratigraphy would be of crucial importance to make a reliable correlation between the studied locations, as well as to promote the selected sections as auxiliary local stratotypes for the JKB. Background of cooperation and envisaged results and benefit: There are several important JKB sequences exposed on Bulgarian and Slovak territories (both belonging to different parts of the Tethyan Belt), which can contribute to the question of drawing of the Jurassic / Cretaceous boundary. Moreover, there are several Bulgarian and Slovak specialists participating in the project and deeply involved in the work of Berriasian Working Group (BWG) of the International Commission of Stratigraphy solving the question of the GSSP establishing of this important stratigraphical boundary since the end of the last millennium. As the drawing of universally valid Stratotype of the boundary is still matter of vivid discussions, the only possible way is constriction of a net of local, studied in details stratotypes, which can bring a remarkable progress.

Biostratigraphy and paleoecology of jurassic and lower cretaceous “fleckenmergel” facies in Western Carpathians
Biostratigrafický a paleoekologický výskum jurských a kriedových fácií typu „fleckenmergel“ v Západných Karpatoch
Program: VEGA
Project leader: RNDr. Antolíková Silvia PhD.
Annotation:Paleontological and paleo ecological research of the facies “fleckenmergel” type in the Western Carpathians has not been well realized. Facies constitute paleo environment of the specific ecosystems in which it is possible on the basis of the fossil record of different groups of organisms (eg. calcareous nannofossíls, fossil tracks, foraminifera and bivalve molluscs) get a lot of information in particular on the age classification of sediments, as these are often heterochronies facies. Facies will be subjected to whole-rock chemical analyses in order to detect and specifying the conditions of formation of the facies “fleckenmergel” type in the Western Carpathians.

Temporal and spatial variations of radon activity concentration and CO2 in the environment.
Časové a priestorové variácie objemovej aktivity radónu a koncentrácie CO2 v prírodnom prostredí.
Program: VEGA
Project leader: RNDr. Smetanová Iveta PhD.
Annotation:The project addresses the investigation of the drivers influencing of the variation of radon activity concentration and carbon dioxide in specific natural environment (cave, soil air). The temporal variation of radon, which contains periodic and non-periodic signals, spans variation of annual to diurnal scale, similar type of variation is also observed for carbon dioxide. The time series of radon and environmental conditions measured in the cave will be systematically analyzed in the time and frequency domains. On the basis of the experimental data a model of seasonal and short-term variations of radon and CO2 will be proposed and tested. The depth profiles of CO2 and radon concentration will be measured in a soil air. The CO2 flux will be quantified for the different soil types and the methods for CO2 flux determination will be compared. The influence of meteorological parameters on radon and CO2 variations in both types of natural environment will be assessed.

Project leader: Mgr. Hrabovský Juraj PhD.
Annotation:Coralline red algae represent common and often dominant constituents of the modern and fossil benthic communities. Their potential for the reconstructions of environmental and paleoecological changes during the Middle Miocene of the Vienna basin and Carpathian Foredeep remains poorly explored. This research project focuses on 1) taxonomy of corallines from newly sampled samples, unpublished core material, and revision of older thin-section material, 2) analysis of community structure and composition on the basis of species, morphotype abundance and non-algal components on the basis of thin-sections, 3) identification of environmental and temporal variation in their composition. Our goal is to determine changes in the composition of the algal limestones along the latitudinal transect in the Vienna Basin and Carpathian Foredeep during the Middle Miocene on the basis of the actualistic and functional-morphological principles, microfacies, sequence-stratigraphy, biogeographical analyses and geochemical methods.

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.

LITHORES - Geophysical multi.parametric modelling of the Earth´s crust and upper mantle in Slovakia
Geofyzikálne multiparametrické modelovanie štruktúry zemskej kôry a vrchného plášťa Slovenska
Program: APVV
Project leader: RNDr. Vozár Ján PhD.
Annotation:In the proposed project we will use multi-parametric joint modelling to obtain information about crustal and upper mantle structures in Slovakia. The primary focus of the project will be on central and eastern Slovakia due to existence of seven measured magnetotelluric (MT) profiles and several seismic sections together with gravimetric data good spatial coverage. In addition to MT, we will use additional geophysical methods (e.g. gravimetric, seismic and geothermal) in joint modelling of old and newly collected data, and regional tectonic information, which will allow interpretation of crustal and also mantle structures. The actual geological methods (geological cross-sections) and data from boreholes will provide information on the structure to depths up to few kilometres. The resulting geophysical-geological models of the selected profiles, complemented by 3D models of selected areas and thermal data will not only provide scientific benefits, but they can also be used in various spheres of economic activity (large constructions, searching for underground water and raw material resources, geothermal energy, etc.). The project’s main objective is the construction of a new comprehensive geophysical model and interpretation of shallow and deep structures of the lithosphere in central and eastern Slovakia. By applying multi-parametric joint inversion scheme (integrated modelling of various measured geophysical data and relevant tectonic models) we will take into account the interdependence and coupling among various geophysical, tectonic and petrological information. The benefits of this modelling consist in possibility to obtain more accurate information on the spatial distribution of geological bodies, tectonic structures and new information about the relationships between the physical parameters of the rocks. Final project outputs will be geophysical and geological multi-dimensional models of the earth's crust and mantle of a given territory.

Geomagnetic field in Slovakia round the 2018.5 epoch
Geomagnetické pole na Slovensku v okolí epochy 2018.5
Program: VEGA
Project leader: Mgr. Valach Fridrich PhD.
Annotation:The project consists of both experimental/observational and theoretical parts that focus on two aspects of the geomagnetic field (GMF). The first aspect is the slow secular variations of the GMF with their main sources in the Earth's interior. The second one is the fast transient changes, which origate in the near-Earth space environment. The experimental part of the project is based on the observations at the Hurbanovo Observatory of the ESI SAS and on the observations performed in terrain. The project will determine the distribution of the elements of the GMF in Slovakia for epoch 2018.5 as well as the rate of changes of these elements. We will also keep on the continuous monitoring of the GMF in the frame of the INTERMAGNET. A new method for producing K indices will be incorporated into the observation program of the observatory. The project will also contribute to theoretical modelling of intense geomagnetic storms. Here the phenomena that cause these storms will be considered; particularly CMEs and CIRs.

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.

Annotation:Integration of the most recent knowledge, findings, and interpretation approaches to investigating the geological structure and tectonic processes of the lithosphere of the Western Carpathians by means of gravimetry, geothermics, deep seismics, structural geology and tectonics. To study the lithosphere, existing available geophysical data as well as geological and tectonic models will be reinterpreted utilizing the most recent approaches and modeling tools. New 2D and 3D crustal and upper mantle models shall be created including refined Moho and LAB. Our reinterpretation will lean on most recent findings from geothermic modeling and magnetotelluric exploration achieved over latest years at our institute. The final lithospheric geological-geophysical models will draw from the results of regional geologic and tectonic investigations.

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.

Global event stratigraphic correlations and paleoenvironments of the Cretaceous and Paleogene formations of the Western Carpathians: biotic, sedimentary and geochemical proxies
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.

Magnetic fabric, sedimentologic and provenance study of clastic formations of the Western Carpathians
Magnetická anizotropia, sedimentológia a proveniencia klastických súvrství Západných Karpát
Program: VEGA
Project leader: Mgr. Madzin Jozef PhD.
Annotation:The aim of the project is an integration of magnetic anisotropy (AMS) and facies analysis for determination of the paleotransport of detrital material of clastic formations of the Western Carpathians (WC). The AMS has been often used as a very helpful petrofabric tool. Its versatility can also be employed as an additional tool in paleocurrent analysis mainly in a situation in which sedimentological indicators are rare, badly interpretable or completely missing. Clastic deposits are particularly important for reconstructions of paleotectonic development of ancient sedimentary basins and are quite common features in sedimentary sequences of individual tectonic units of the WC. A combination of paleotransport data, petrographic compositon and heavy mineral analysis of the deposits studied allows us to specify the nature and extent of remote or barely identificable source areas and hence to successfully decipher their paleogeographic arrangement as well as the paleotectonic development of the WC.

Meso- and micro-meteorological exploration of the occurrence of hydrometeors in boundary layer of the troposphere based on pasive evaluation of changes of electromagnetic radiation from anthropogenic sources
Mezo- a mikro-meteorologický priskumvýskytu hydrometeorov v prízemnej vrstve troposféry na základe pasívneho vyhodnocovania zmien elektromagnetického žiarenia z antropogénnych zdrojov.
Program: VEGA
Project leader: RNDr. Nejedlík Pavol CSc.
Annotation:Intensive concvective phenomena show strong variability in space and time, from tenths to hundreds of meters and from tenths of seconds to minutes. Automatized meteorological networks on the ground are not able to monitor the occurrence and dynamics of these phenomena in sufficient resolution. Atmospheric hydrometeors interfere electromagnetic signal in atmosphere. The magnitude of the interference is relative to the intensity of precipitation. This fact enables us to detect the hydrometeors by monitoring the changes of electromagnetic signal either by active broadcasting of the signal and detecting its part reflected by the hydrometeors or by passive receipt of the signal from different broadcasters. The network of meteorological radars is able to detect mesometeorological phenomena in Slovakia mostly over the level 700-1000 m above ground. The measurement of the hydrometeors, including their dynamics, below this layer by multi-frequency passive radiolocation can bring necessary information in this space.

Mineralogy, petrogenesis and metallogenetic potential of the Pliocene intra-plate magmatism of Western Carpathians
Mineralógia, petrognéza a metalogenetický potenciál Pliocénneho vnútro-platňového magmatizmu Západných Karpát
Program: VEGA
Project leader: doc. RNDr. Hurai Vratislav DrSc.
Annotation:Alkali basalts of southern Slovakia contain xenoliths of igneous rocks, which do not occur in Inner Western Carpathians. Observed rock types involve mafic gabbroic cumulates, syenites, granites, carbonatites and metasomatic products of their interaction with crust (skarns). Magmatic rocks originated during fractional crystallization of basaltic magma and partial melting of surrounding rocks. The project is targeted to deciphering mineralogical, geochemical, geochronological and petrological characteristics of magmatic rocks, evaluation of their genesis, geotectonic setting, source as well as metallogenetic potential with special emphasis on possible occurrence of critical metals, such as U, Th, Nb, Ta and rare earth elements.

Interaction models of crustal and mantle rocks with fluids in accretionary wedges of the Western Carpathians, eastern Alps and northern Turkey; correlation of P-T-X-t parameters
Modely interkcie kôrových a plášťových hornín s fluidami v akrečných prizmách Západných Karpát, váchodných Álp a severného Turecka; korelácia P-T-X-t parametrov
Program: APVV
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.

WECAFARE - Multidisciplinary research of geophysical and structural parameters, and environmental impacts of faults of the Western Carpathians
Multidisciplinárny výskum geofyzikálno-štruktúrnych parametrov a environmentálneho vplyvu zlomov Západných Karpát
Program: APVV
Project leader: RNDr. Madarás Ján PhD.
Annotation:Data concerning faults and their parameters is important information for basic geological research as well as for landscape planning, building activities and assessment of health and natural hazards of geological environment. Ambition of the project is to localize the trace and to identify some spatial, structural, physical, dynamic and age parameters of selected dislocations using combination of multidisciplinary field research methods. Selected faults will be mapped by geophysical field survey methods in combination with bio-detection, detected by radon (Rn) emanations measurements and by means of remote sensing (RS) and digital terrain model (DTM) images, investigated structurally and some of them will be dated. The recent activity of selected fault(s) will be monitored by measurements of seismic events, by analysis of both their focal mechanisms and historical earthquakes and by periodical geodetic measurements based on GNSS technology. First time, for the detection of recent vertical movement along specific fault (the Vikartovce fault in the Tatra region), the very accurate measurements of gravity values will be applied in the Western Carpathians. Fault structures will also be evaluated in relation to some large crustal discontinuities, whose surficial expressions are brittle faults, and which are reflected in anisothropies of lithospheric geophysical fields (recorded in seismic, gravimetric, geo-electric, magnetic and magnetoteluric sections and maps). Expected results of the project will be the structural schemes of accurate traces of studied discontinuites with their specified parameters (inclination, fault damage zone width and character, permeability for fluids, saturation by water, Rn emanations, kinematics, relation to slopes instabilities, recent activity). Potential impact of fault structures on population health will be investigated by radioactivity measurements at residences situated in touch with detected traces of faults with recorded Rn values.

Evaluating preservation potential of benthic responses to hypoxic and anoxic events in the fossil record
Potenciál na zachovanie hypoxických a anoxických eventov a ich účinkov na bentické spoločenstvá vo fosílnom zázname
Program: APVV
Project leader: Mgr. Tomašových Adam PhD.
Annotation:Anoxia and hypoxia can severely reduce ecosystem functioning and increase probabilities of species extinction. The effects of oxygen depletion on benthic communities can lead to preservation of laminated strata, small size of macrobenthic organisms, outbreaks of hypoxia-tolerant, opportunistic species, and high concentrations of organic matter. However, the preservability of benthic responses to anoxia or hypoxia in the fossil record will be low if, after the renewal of oxygen concentrations, recovery time for burrowing organisms is relatively long, the depth of bioturbation is relatively large, and/or background sedimentation rates are too slow so that post-event bioturbation will lead to high time averaging, i.e., stratigraphic mixing of hypoxia-tolerant species with hypoxia-sensitive species. The ratio of sedimentation to bioturbation intensity is one of the key variables determining the preservation potential of such events in the fossil record. In this project, we will provide constraints on the range of sedimentary and mixing conditions under which benthic responses to hypoxia or anoxia can be preserved, and thus improve the identifiability of anoxic or hypoxic crises in the fossil record. First, we will evaluate preservation potential of benthic abundance and size patterns responding to oxygen depletion in sediment cores from two continental shelves, including (1) the southern California Shelf and (2) the Adriatic Sea. Second, we will assess patterns in size and abundance of benthic communities in stratigraphic successions characterized by alternations of normoxic, hypoxic, and anoxic conditions in semi-enclosed basins from the Late Triasic, Early Jurassic, and Middle Miocene. We will investigate the scales of time averaging and burial and mixing rates in Holocene sediment cores, and spatial and temporal gradients in size, abundance, and growth rate of benthic groups in habitats with varying organic enrichment and oxygen concentrations in the fossil record.

Solution of actual problems in geophysical and geodetic detection of underground cavities in environmental and archaeological applications
Riešenie aktuálnych problémov geofyzikálnej a geodetickej detekcie podpovrchových dutin v environmentálnych a archeologických aplikáciách
Program: VEGA
Project leader: Mgr. Zahorec Pavol PhD.
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).

Sedimentary paleoenvironments and transport-depositional mechanisms in the Paleogene formations of the Central Western Carpathians
Sedimentárne paleoprostredia a transportno-depozičné mechanizmy v paleogénnych súvrstviach Centrálnych Západných Karpát
Program: VEGA
Project leader: Mgr. Starek Dušan PhD.
Annotation:Paleoenvironmental reconstructions and definition of transport-depositional mechanisms are a key to analyse of sedimentary basins. Implementation of sedimentological, palaeoecological, geochemical and statistical analysis allows to define the fundamental depositional environments, architecture of the sedimentary basin fill, transport-depositional mechanisms as well as genetic facies and their vertical cyclicity within studied Paleogene units in the Central Western Carpathians. Synthesis of data on lateral and vertical development of the paleoenvironments, that is preserved within architectural elements of the basin fill, and transport-depositional specifications will lead to the definition of depositional model of the basin as well as to the clarifying knowledges about autocyclic and alocyclic factors affecting the sedimentation. The acquired knowledge will contribute to the reconstruction of palaeogeography and tectogenesis of the Carpathian Paleogene basins.

U-Th-Pb zircon dating of Variscan granitic and Alpine subvolcanic intrusive rocks of Western Carpathians: implications to orogenic and metallogenetic processes
U-Th-Pb zirkónové datovania varískych granitov a alpínskych subvulkanických intruzívnych hornín Západných Karpát: implikácia k orogenetickým a metalogenetickým procesom.
Program: APVV
Project leader: RNDr. Broska Igor DrSc.
Annotation:The project is oriented on the precise dating of selected granites of principal orogenetic events which formed recent Western Carpathians i.e. main Variscan and Alpine orogenesis. Recently the zircon is widely used for dating of granites and especially by sensitive high resolution ion microprobe (SHRIMP) dating which is only way how to recognise the multiply growing of zircons during orogenic events. The project is focus on dating of granites within Štiavnica stratovolcano to identify the formation time of principal metallogenetic events. The Korean laboratory is experienced with dating of the Tertiary zircons in spite of long half-time decay of uranium from zircon therefore would be desirable to date the samples also from the Slovak neovolcanic rocks in the Korea – SHRIMP facility is not accessible in the central Europe. The second task of project is the dating of Variscan granites which are perhaps related to collisional processes. Such granites are not well-recognised and the data will be important to solve the problem of shortening within the Variscan orogeny which formed the recent crystalline basement of the Western Carpathians including the Tertiary neovolcanic rocks. The result of dating will be used for geodynamic reconstruction.

HARDROCKS - Ultrahogh-pressure metamorphic rocks and granitoids of colisional orogens: P-T-X conditions, formation of microdiamonds, stability of accessory minerals nd geodynamic evolution
Ultravysokotlakové metamorfované horniny a granitoidy kolíznych orogénov : P-T-X podmienky, tvorba mikrodiamantov, stabilita akcesorických minerálov a geodynamický vývoj
Program: APVV
Project leader: RNDr. Janák Marian DrSc.
Annotation:The project deals with ultrahigh-pressure metamorphism and granitoid magmatism in collisional orogenic zones. Ultrahigh-pressure metamorphic rocks - eclogites, garnet peridotites, gneisses, granulites and various types of granitoids will be investigated in selected terrains including the Western Carpathians, Eastern Alps (Pohorje), Scandinavian Caledonides and Rhodopes. These will serve as case studies of geodynamic evolution in collisional orogens of different age. Major objectives of the project include phase relations of mineral assemblages and thermodynamic (P-T-X) conditions during subduction and exhumation. A special attention will be paid to identification of ultrahigh- pressure phases to elucidate formation of microdiamonds. There will be a possibility to find new occurrences of UHP rocks. Granitoids of the Western Carpathians will be studied to determine their genesis, age and geotectonic setting with emphasis to solve their geodynamic evolution during Variscan orogeny. Detailed study of accessory minerals (monazite,allanite, rutile, ilmenite, apatite, tourmaline, zircon) will be focused on their stability in magmatic, post-magmatic and metamorphic processes, geochronological dating and reconstruction of the P-T-t paths. The project will be carried out using modern and innovative methods and the outputs from the project may expand knowledge on geodynamic evolution of Earth´s lithosphere in collisional orogenic zones.

SCDE - Linking the evolution of Mesozoic vertebrates to climate in Eastern Laurasia: High-resolution analysis of unique fossil tissues from Chine
Vplyv klimatických zmien vo východnej Laurázii na evolúciu druhohorných stavovcov: vysokorozlišovacia analýza unikátne fosilizovaných tkanív z Číny.

Project leader: Mgr. Milovský Rastislav PhD.
Annotation:The aim of this multidisciplinary research project is to understand the evolutionary dynamics of the Laurasian climate and vertebrate fauna using modern quantitative analytical and imaging techniques and biostatistical processing of fossilized tissues and abiotic structures. The geological setting to be explored in this research comprises the Middle Jurassic to Upper Cretaceous deposits in remote areas of Inner Mongolia and Liaoning provinces in China. The large-scale and vegetation free geological exposures at the surface in this region provide a unique study area within which primary geological data and fossil specimens can easily be collected. As this vast area has remained mostly under-explored, we expect to make new paleontological discoveries of both regional and global importance. This study represents the first time such a synergistic and allencompassing analysis of these important fossil beds has been undertaken. These deposits were formed under very important and unique paleogeographic, environmental and climatic conditions that controlled the regional endemism and faunal and floral turnovers. Dynamics changes of the vertebrate paleofauna determines our major research activities in the field of paleoclimatology, paleogeography, paleobiology, and paleogenomics. Finally, this project has been arranged in collaboration with Inner Mongolia Museum of Natural History, and with Japan Synchrotron Radiation Research Institute (JASRI Spring-8). We shall use Slovak-Chinese Dinosaur Expeditions (SCDE) as the public relation name of this project for a large-scale dissemination of the project outcomes.

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.
