Program: Multilaterálne - iné
Project leader: Mgr. Zahorec Pavol PhD.
Annotation:AlpArray is a large collaborative project with the aim of carrying out cutting edge research using seismological as well as associated Earth sciences data and geodynamic synthesis and modelling in order to better understand the geodynamics of the greater Alpine area and its seismic hazard. The main actions to realise this goal are: 1) collecting top-quality seismological data from a dense network of temporary seismic stations that complements the permanent stations to ensure homogeneous coverage of the greater Alpine area (“AlpArray Seismic Network”); 2) deploying specifically designed temporary geophysical arrays (“AlpArray Complementary Experiments”) along profiles, swaths or networks that are devoted to the resolution of specific structures and targeted questions; 3) acquiring associated Earth sciences data (such as gravity, electro-magnetics, geology, GPS, etc.); 4) analyzing and interpreting the collected dataset in multidisciplinary ways and developing new quantitative geodynamic models of the Alpine area in order to further our understanding of mountain building processes.

Korelácia jursko - Correlation of Jurassic-Cretaceous boundary sequences in the Tethyan Mediterranean Belt and adjacent regions based on geodynamics (lithostratigraphy, sequence analysis, paleogeography), micro- and nannofossil record and global climate and sea-level change
Korelácia jursko-kriedových hraničných sekvencií v tethidnom mediteránnom pásme a priľahlých oblastiach založená na geodynamike (litostratigrafia, sekvenčná analýza, paleogeografia), mikro- a nanofosílnom zázname a globálnych zmenách podnebia a úrovne mor
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.

WOLF - Working group on larger foraminifera: stratigraphy, palaeoecology, palaeoenvironment
Pracovná skupina pre výskum veľkých foraminifer: stratigrafia, paleoekológia, paleoprostredie
Program: COST
Project leader: doc. RNDr. Soták Ján DrSc.
Annotation:The main purpose of the COST projec is to build a framework of scientists who can actively work on the taxonomy of LBF throughout the Cenozoic. Taxonomy is an extremely detailed work and requires both expertise and access to extensive collections. Putting together scientists from different countries is possibly the only chance we have to tackle LBF in all their diversity. This can only be achieved by continuous meetings and continuous discussion on species definitions, delineation of characters and, consequently, stratigraphic interpretations and microfacies analyses of all selected taxa to be formally recognized.

Project leader: RNDr. Vozár Ján PhD.
Annotation:The project is focused on the geophysical study the Earth’s lithosphere of the Carpathians in the area of Slovakia. Newly collected and old magnetotelluric (MT) data and geophysical (gravity and thermal) data available from previous experiments will be modelled by joint inversion algorithms. We will localize the accumulations of the highly conductive fractions, either fluids or electronic conductors related to tectonic disturbances in the crust of Slovakia. The Carpathian Conductivity Anomaly (CCA) will be identified among structures and imaged along the contact zone between the Inner and Outer 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.

Temporal and spatial changes in the composition of benthic algal-dominated assemblages of the Vienna Basin and Carpathian Foredeep during the Middle Miocene
Časové a priestorové zmeny v zložení bentických spoločenstiev dominantných s koralinnými riasami Viedenskej panvy a Karpatskej priehlbiny v strednom miocéne.
Program: VEGA
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.

Rock-forming and accessory minerals during retrogression of high-grade metamorphic and metamagmatic rocks from orogenic belts.
Horninotvorné a akcesorické minerály počas retrogresie vysokostupňových metamagmatických a metamorfovaných hornín
Program: VEGA
Project leader: RNDr. Petrík Igor DrSc.
Annotation:Subduction of rocks in orogenic belts followed by exhumation is manifested by re-equilibration of mineral associations first to adapt to ultrahigh-pressure (UHP) conditions of eclogite facies, then to the conditions of lower pressure but high temperature granulite facies. Re-equilibration may almost fully obliterate previous UHP history, however, some accessory minerals and inclusions in garnet still witness previous high pressure. Project is oriented to finding, identification of such minerals, diamonds, fluid inclusions, Ca-rich garnet relics, phengites, (U)HP monazites, which can be chemically dated. We shall study mostly diamond-bearing rokcs from the Caledonides (Sweden, Norway), i.e. the orogenic belt, which has not experienced any subsequent orogeny. On the contrary, Western Carpathians, rocks of the northern Veporic zone, recorded three orogens, Ordovician, Variscan and Alpine (Cretaceous) and represent a challenge – to distinguish these events according to the ages and metamorphic degree.

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.

Integration of latest findings and approaches of gravimetry, geothermics and deep seismics for determining lithospheric structure and tectonics focusing on Western Carpathians
Integrácia najnovších poznatkov a interpretačných prístupov gravimetrie, geotermiky a hlbinnej seizmiky pre určenie stavby a tektoniky litosféry s dôrazom na Západné Karpaty

Project leader: RNDr. Vajda Peter PhD.
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. The project aims at improving the quality of basic earth science research in Slovakia. We assume also deliverables in terms of exploiting geo-sources and renewable energy.

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.

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. Additional goals refer to the interpretation and reconstruction of pre-Tertiary basement in southern Slovakia, as well as minimum age estimates of host pyroclastic maar deposits.

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.

Preservation potential and effects of hypoxic events on benthic communities in the fossil record
Potenciál na zachovanie hypoxických eventov a ich účinok na bentické spoločenstvá vo fosílnom zázname
Program: VEGA
Project leader: Mgr. Tomašových Adam PhD.
Annotation:Hypoxic events can strongly reduce productivity and nutrient recycling in ecosystems and increase probability of species extinctions. Preservation potential of hypoxic events in the fossil record can be low if there is a relatively long time for ecosystem recovery in the wake of oxygen depletion, if depth of bioturbation is large, and/or if sedimentation rate is very slow. In this project, we will use actualistic and paleoecological methods to determine conditions under which benthic responses to hypoxic events can be preserved in the fossil record. First, we will assess preservation potential of benthic respones to hypoxia in Holocene sediments on continental shelves off southern California and in the Adriatic Sea. Second, we will evaluate temporal and spatial variability in the composition of benthic communities in successions characterized by alternations of normoxic and hypoxic conditions in semi-enclosed basins during the Triassic and Early Jurassic (Alps) and Miocene (Vienna and Korneuburg basins).

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.

Annotation:The Little Carpathians Mts. source zone belongs to the most seismic active regions on the territory of Slovakia. The goal of submitted project is to better understand the seismic regime of this area. The project is focused on acquiring and analyses of geophysical data, mainly seismic monitoring, reinterpretation of macroseismic data and data on historical earthquakes. One of the main intentions of the project is to refine the existing seismotectonic model of the Little Carpathians Mts. source zone. Data obtained within the frame of proposed project belong to the crucial inputs for seismic hazard assessment. The high importance of this analysis for the investigated region is emphasized by vicinity of the Jaslovské Bohunice nuclear power plant.

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.
Program: APVV
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.

Composition, sources, transport and paleogeographic conditions of deposition of siliciclastic material in Triassic/Jurassic boundary formation of units of the Tatra Mts
Zloženie, zdroje, transport a paleogeografické podmienky sedimentácie siliciklastického materiálu v triasovo/jurských hraničných súvrstviach jednotiek oblasti Tatier
Program: VEGA
Project leader: Mgr. Vďačný Marek PhD.
Annotation:Significant environmental and evolution events took place during the Triassic/Jurassic boundary. Profile studies of the Triassic/Jurassic boundary formations of the Western Carpathians are therefore of a high importance. In viewpoint of evaluation of paleogeographic, paleoecologic and especially paleoclimatic conditions and their changes during the Triassic/Jurassic boundary, they represent important formations. Therefore, the project aims to solve problems of composition, sources and material transport of the Triassic/Jurassic boundary formations in the Vysoké Tatry Mts, using complex petrographic and geochemical approaches. Moreover, it will clarify the weathering intensity in the source area, paleoclimatic conditions, tectonic mobility, and geodynamic developments and test the validity of existing paleogeographic models.
