EAlpG - European Alps Geoid
Európsky Alpský geoid
Duration: | 1. 1. 2022 - 31. 12. 2027 |
Program: | Multilaterálne - iné |
Project leader: | Mgr. Zahorec Pavol PhD. |
Annotation: | The Global Navigation Satellite Systems (GNSS) have caused a fundamental and lasting change in the field of Geodesy. Due to the missing link to the gravity field of the Earth, GNSS measurements yield purely geometric heights relative to a reference ellipsoid. To derive physical heights, additional information is necessary that describe the undulations of the height reference surface. This information is computed from global or regional gravity field models and is denoted as geoid or quasigeoid models. The combination of GNSS measurements and geoid models provides an efficient tool to determine heights. However, it does not reach the accuracy of the traditional leveling methods. Height reference systems are therefore still measured on a national basis and by the use of precision leveling. The national height reference systems differ regarding the definition (height type), the applied numerical standards as well as the choice of the geodetic datum (zero level). In the geodetic practice this results in different height levels that become most apparent at the national borders, yielding up to about 50 cm (between France and Germany). The cooperation is expected to enable the following achievements: • Harmonization of the underlying data for regional geoid modeling in the border regions of the partnering countries, • Determination of a joint geoid/quasigeoid model in the Alpine region (European Alps Geoid), • Analysis of the datum differences between the national height reference frames of the partnering countries, • Derive appropriate transformation rules between the national height reference frames, • Validation of global and continental gravity field models. |
FAIRNESS - FAIR Network of micrometeorological measurements, Akcia CA20108

Annotation: | The FAIRNESS action intends to improve standardization and integration between databases/sets of micrometeorological measurements that are part of research projects or local/regional observational networks established for special purposes (agrometeorology, urban microclimate monitoring). Addressing identified challenges requires an effective transboundary network of researchers, stakeholders (extension services and environmental agencies, local authorities and ministries, SME) and civil society (specialized and general public) from Europe and beyond to identify and fill knowledge gaps, standardize, optimize and promote new environmental-tailored measurement and control procedures, enhance research effectiveness and improve dissemination. |

D-Rex - Deposit-to-Regional Scale Exploration
Od ložiskového k regionálnemu prieskumu
Duration: | 1. 12. 2020 - 30. 11. 2023 |
Program: | ERANET |
Project leader: | RNDr. Vozár Ján PhD. |
Annotation: | Mineral deposits are a small part of a very large geological context, the so-called mineral system. The first objective of D-Rex is to build onto this new paradigm with geophysical data from three prospective areas in Sweden, Greenland and Finland. Therefore, the second objective of D-Rex is the integration of multi-facetted geophysical data acquired at those prospective areas. The third objective of D-Rex is the unification, optimum integration and visualization of geological and geophysical data on the basis of the Common Earth Modelling (CEM) concept. Key element of the project involves: Electromagnetic (deposit scale) surveys; Development of multimethod 3D modelling/inversion technique; Joint inversion assisted by machine learning techniques to couple different geophysical parameters, to uncover correlations between them as well as their absence; Regional to deposit scale models integration into Common Earth Model based on all available geophysical and geological data; Building predictivity maps based on the regional models; Correlation and interpretation of regional scale together with deposit scale models. The outputs of this project will be novel technologies and workflows that directly address Europe’s goal to become self-sufficient in terms of raw materials. We will achieve an improved understanding of the geological history of key mineral districts in Europe and by proxy also other similar or related European metallogenic zones. This understanding will result in improved models for the formation of minerals and allow us to better predict their expected locations. This will lead to the discovery of new, higher-grade and possibly larger mineral deposits and thus better supply. |

OPENSENSE - Opportunistic precipitation sensing network
Oportunistické formy merania atmosferických zrážok
Duration: | 13. 10. 2021 - 12. 10. 2025 |
Program: | COST |
Project leader: | Mgr. Onderka Milan PhD. |
Annotation: | Despite advances in remote sensing, precipitation observations remain one of the weakest links in the description of Earth’s water cycle. This is especially critical in the face of climate change, human-induced hydrologic changes e.g. due to rapid urbanisation, and consequent increase in frequency and magnitude of extreme events. Opportunistic sensing can greatly improve spatial and temporal resolution of standard precipitation monitoring networks on continental scale by complementing them with measurements from personal weather stations or devices primarily not intended for precipitation monitoring such as commercial microwave links or broadband satellite terminals. The number of opportunistic sensors has already now exceeded traditional in-situ observations by an order of magnitude, and it is increasing exponentially. Nevertheless, it is still unclear how to make this data operationally accessible, achieve robust quality control of these observations, and integrate them into standard observation systems.OPENSENSE brings together scientists investigating different opportunistic sensors, experts from national weather services, owners of sensor networks, and end-users of rainfall products to build a worldwide reference opportunistic sensing community. It will i) overcome key barriers preventing data exchange and acceptance as hydrometeorological observations ii) define standards to allow for large-scale benchmarking of OS precipitation products developing new methods for precipitation retrieval iii) coordinate integration of the opportunistic observations into traditional monitoring networks, and iv) identify potential new sources of precipitation observations. These coordinated activities will boost uptake of OS as precipitation observation methods and enable generation of high-quality precipitation products with unprecedented spatial and temporal resolution. |
Benchmark experiments and modeling of alloy systems involving flow and solidification

Duration: | 1. 1. 2023 - 31. 12. 2024 |
Program: | Mobility |
Project leader: | doc. Mgr. Guba Peter PhD. |
Annotation: | Regions of mixed solid-liquid phases, or so-called mushy regions, play an important role in geology and geophysics. The phase change in the mushy layers is a source of convective motions leading to the redistribution of mass and heat in the solidifying system. A striking consequence is the formation of vertical chimneys through which plumes of buoyant fluid rise. The project aims at understanding the growth of a mushy layer with chimney convection. We will design and conduct a series of benchmark solidification experiments on salt solutions. Theoretical modelling will focus on understanding the factors controlling the convective mushy layer growth and the evolution of its internal structure over a long time horizon. A further aim will be to quantify the convective fluxes between the mush and the molten alloy, which are crucial for macrosegregation. Understanding the above phenomena is vital for the explanation of the origin of the Earth's core convection, magma solidification as well as the mass transport between the shells and subsurface oceans of the icy moons. |

Program: | VEGA |
Project leader: | doc. Mgr. Gális Martin PhD. |
Annotation: | Sufficiently accurate estimates of earthquake ground motion (EGM) at a site of interest is important for mitigation of potential damage during future earthquakes. EGM and associated damage during an earthquake can be significantly affected by site effects (e.g., an anomalous amplification of EGM). Key structural parameters, with potential to cause site effects, were identified using extensive numerical simulations of EGM performed in the framework of projects NERA (FP7) and SIGMA (EDF, CEA, Areva, ENEL). The simulations and analysis focused on deterministic models. An ongoing ID-Effects project (APVV) investigates also random variations of small-scale heterogeneities of material parameters (e.g., seismic wave speeds). The stochastic character of the variations requires an additional specific analysis. The most important aspect of the additional investigation is analysis of stability of the key structural parameters in complex stochastic models. |

DISLOCAT - Atlas of tectonic dislocations of the Earth´s crust in the territory of Slovakia
Atlas tektonických dislokácií zemskej kôry na území Slovenska
Duration: | 1. 7. 2022 - 30. 6. 2026 |
Program: | APVV |
Project leader: | RNDr. Bezák Vladimír CSc. |
Annotation: | The knowledge of tectonic dislocations (faults) is essential for various areas of economic activity (e.g. large transport constructions, dams, nuclear power plants, mineral exploration and exploration of geothermal waters), and it has an impact on environmental issues (e.g. risks, slope deformations, sites for radioactive waste seismic storage). The systematic processing of data on the dislocations of crust in Slovakia in the form of a comprehensive monograph is highly needed. This is the aim of our DISLOCAT project. Based on the excerption of available published and archived data, all significant tectonic dislocations of crust will be characterized according to uniform criteria. We will focus on the faults from the youngest Neoalpine tectonic development, many of which are still active today. The basic parameters of the faults will include the manifestations of the faults in the geological map and/or aerial and satellite images, its course, inclination and depth, thickness of the disturbed zone, structural data and kinematics, age, seismicity, available geodetic measurements of recent movements, geomorphological manifestations and springs of water or emanations. Great attention will be paid to seismoactive fault zones. The information about selected faults will be collected and made more precise by field research into the geological structure and geophysical, mainly magnetotelluric measurements. |

Temporal and spatial changes in the coralline algal assemblages from the shallow-water Tertiary limestones of the West Carpathians
Časové a priestorové zmeny v spoločenstve koralinných rias a treťohorných plytkovodných vápencov Západných Karpát
Duration: | 1. 1. 2022 - 31. 12. 2025 |
Program: | VEGA |
Project leader: | Mgr. Hrabovský Juraj PhD. |
Annotation: | Coralline algae are common constituent of the Tertiary shallow-water carbonates from the West Carpathians. They are suitable organisms for consideration of the global climate changes because distribution of these algae is driven mostly by sea-water temperature and irradiance. Global climatic events documented in the Tertiary West Carpathian limestones were yet not considered using coralline algal assemblage analyses and biocoenoses in which coralline algae are found. For purpose to improve our inferences, paleontologiclal and sedimentological results will be confronted with geochemical signal of the isotopic content from the exoskeletons of selected organisms. |

Genesis and evolutionary stages of the granite massif in the Tatric part of the Nízke Tatry Mts.
Genéza a evolučné štádiá granitového masívu tatrickej časti Nízkych Tatier
Duration: | 1. 1. 2020 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | RNDr. Broska Igor DrSc. |
Annotation: | Project is focused on solution of genesis and evolution of granite massif in the Tatric part of the Nízke Tatry Mountains where up to now seven granite types were recognised. In spite of the importance of this large granite massif the modern complex geochemical and petrological analysis along with modern geochronology and solving genetic time sequence (mainly on the basis of the monazite chemical dating and isotopic zircon analysis) still absents. The new obtained data for the granite massif of the Nizke Tatry Mts., which has been repeatedly metamorphosed and has metallogenetic significance, will be correlated with the granites in the rest of the West-Carpathian crystalline basement and also with the Variscan Europe. |
Density analysis of the rock environment based on surface and underground gravity measurements
Hustotná analýza horninového prostredia na základe povrchových a podzemných gravimetrických meraní.
Duration: | 1. 1. 2020 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | Mgr. Zahorec Pavol PhD. |
Annotation: | Density of rocks is a basic parameter characterizing the rock environment from the point of view of gravimetry. Its correct estimation for a given area is a necessary condition for correct processing and interpretation of gravimetric measurements. In the case of Slovakia that fact is emphasized by the rugged mountainous character of our territory, and at the same time complicated geological structure of the Western Carpathians. It is known that laboratory density analyzes of rock samples do not always reflect the natural density properties of the rocks. For that reason methods of direct analysis of gravimetric measurements are becoming increasingly important. In particular, the combination of surface and underground gravimetric measurements is a very suitable approach. The aim of the project will be to develop this methodology using the most modern geophysical and geodetic methods. The subject of the research will also be the application of the above-mentioned methodology in the archaeological research. |
Chronology of global events in Tethyan and Parathethyan basins of the Western Carpathians infered from evolution and life environments of fossil planktonic organisms.
Chronológia globálnych udalostí v tethýdnych a paratethýdnych panvách Západných Karpát na základe evolučného vývoja a životných podmienok fosílnych planktonických organizmov.
Duration: | 1. 1. 2020 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | doc. RNDr. Soták Ján DrSc. |
Annotation: | Planktonic organisms are known as a most sensitive components of marine and oceanic ecosystems in the present time and geological history. Therefore, they belong to principal zonal microfossils, which have been used to compile the geological time scale. Bioevents in evolution of planktonic fossils (foraminifera, nannoplankton, tintinids, etc.) are correlable with stratigraphic boundaries of Mesozoic systems (J/K, K/T), periods (P/E, O/M), stages (Apt/Alb, Cen/Tur, Lut/Bar), biozones, magnetozones, isotope curves, orbital cycles, etc. Besides of crucial importance for biostratigraphy, the plankton is considered as a highly sensitive biotic proxy for climate, CO2 level, produktivity, eustacic changes, dissolved oxygen, circulation, isolation and others. The project is intended to identify of planktonic bioevents in the Western Carpathian sections, their correlation with phylogenic features, international stratotypes and global paleoenvironmental changes of the Tethyan and Paratethyan basins. |
Paleoproxy - Chronostratigraphic standards and sedimentary archives of global changes of biota and paleoenvironments of the Western Carpathians

Program: | APVV |
Project leader: | doc. RNDr. Soták Ján DrSc. |
Annotation: | Sedimentary archives preserve a time-stratigraphic boundaries and records of evolutionary development, life environments, climatic conditions and the Earth global changes. The project is focused to integrated research and multiproxy analysis of stratigraphic sections of the Western Carpathians. The first objective of project will be to provide the data for determination of stratigraphic boundaries and their time-scale calibration with international stratotype sections GSSP. The most usefull for dating of marine sediments are planktonic organisms, which provide a bioevents for global correlation of stratigraphic stage boundaries, biozones, magnetochrons, isotope curves, orbital cycles, etc. Beside of crucial importance for stratigraphy, the fossil microorganisms also provide a sensitive proxy for climatic conditions, CO2 content, eustatic sea level, oxygen concentration, circulation, isolation, and another paleoenvironmental changes. Terrestrial environments will be analyzed in term of mammalian biostratigraphy, vertebrate paleoecology and paleovegetation. The aim of the project will be identification of stratigraphic boundary events at reference sections of the Mesozoic and Cenozoic formations of the Western Carpathians, and their correlation with geologic time scale and global changes of paleoenvironments in Tethyan and Paratethyan basins. |

Complex analysis of the effects of rising air temperature on rainfall extremes in Slovakia
Komplexná analýza vplyvu rastúcej teploty vzduchu na extremalitu zrážok na Slovensku
Duration: | 1. 1. 2021 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | Mgr. Onderka Milan PhD. |
Annotation: | Climate extremes, including extreme rainfall and heat waves, have intensified in the recent decades. This trend is attributable mainly to higher temperature and subsequent higher water vapor content in the atmosphere. A simple relation of precipitation extremes and air temperature is site specific and the relationship between air temperature, dew point temperature and precipitation extremes should be evaluated for each site individually. To our best knowledge, no study has yet been conducted in Slovakia that would deal with the complex stochastic characteristics of precipitation extremes in relation to air temperature, humidity and climate indices simultaneously. In this project we will develop novel process-oriented procedures to estimate design rainfall values. In addition, we will project annual, seasonal, daily and sub-day rainfall sums and their quantiles for time horizons (eg 2030, 2050 and 2080) based on the outputs of the regional climate modelsRCMs (e.g. CORDEX or ALADIN). |

Magnetotelluric modeling of deep tectonic structures at the European pltform and Carpathian block interface.
Magnetotelurické modelovanie hlbokých tektonických štruktúr na kontakte Európskej platformy a Karpatského bloku.
Duration: | 1. 1. 2020 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | RNDr. Bezák Vladimír CSc. |
Annotation: | The development during the youngest phases of the current orogeny of the Western Carpathians is atypical compared to the other young orogeny in the world. The cause is the oblique collision of the Carpathian block with European platform leading to the formation of highly complex subsurface tectonic structures at the interface of these two plates. It is also important to trace the manifestations of this oblique collision in the deep tectonic structures. This is only possible through geophysical methods. The project aims to analyze the deep tectonic structures at the interface between European platform and Carpathian block by magnetotelluric modeling using seismic, gravimetric and magnetic data. |
Metamorphic processes in collisional orogenic zones

Duration: | 1. 1. 2020 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | RNDr. Janák Marian DrSc. |
Annotation: | The project deals with metamorphic processes in collisional orogenic zones, mainly ultrahigh-pressure metamoprhism (UHPM). Several types of rocks - eclogites, garnet peridotites, gneisses, granulites and migmatites will be investigated in selected terrains including the Western Carpathians, Eastern Alps (Pohorje), Scandinavian Caledonides and Rhodopes. 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 including microdiamonds. Detailed study of accessory minerals (monazite, zircon, rutile) will be focused on their stability in metamorphic processes with implications for 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. |

Mobility and accumulation of critical elements during formation and alteration of orogenic carbonatites
Mobilita a akumulácia kritických prvkov pri vzniku a alterácií orogénnych karbonatitov
Duration: | 1. 1. 2022 - 31. 12. 2024 |
Program: | VEGA |
Project leader: | doc. RNDr. Hurai Vratislav DrSc. |
Annotation: | Minerals of critical metals (Zr, Nb, Ta, REE) are prospective raw materials that trigger the recent technological progress. These elements are preferably bound to carbonatites, i.e. igneous rocks composed predominantly of carbonates. The overwhelming part of recent knowledge concerns carbonatites in stable cratons. Recently, however, the metallogenetic potential of orogenic carbonatites from tectonic plate junctions has been investigated. These carbonatites are intensely reworked, which affected the behavior of critical elements. The aim of the project is mineralogical, geochemical and geochronological research of selected carbonatite deposits in Mozambique and China in order to identify processes of mobilization, accumulation and disproportionation of critical metals during magma fractionation and superimposed metamorphic, hydrothermal and metasomatic reworking. The main output of the project will be the formulation of criteria for optimizing exploration methods for orogenic carbonatites. |
ALCABA - New Bouguer anomaly map of the Alpine-Carpathian area: a tool for gravity and tectonic applications
Nová mapa Bouguerových anomálií alpsko-karpatskej oblasti: nástroj pre gravimetrické a tektonické aplikácie
Duration: | 1. 7. 2020 - 30. 6. 2024 |
Program: | APVV |
Project leader: | Mgr. Zahorec Pavol PhD. |
Annotation: | Exact calculation of the complete Bouguer anomalies (CBA) plays an important role in applied gravimetry, whereas these serve as the main input into geological, structural and tectonic interpretation (in CBA maps all non-geological influences – mainly the manifestation of relief - are suppresed and the density inhomogeneities in lithosphere structure are displayed). The team of investigators of the submitted project was invited in the frame of an European initiative (AlpArray Gravity Research Group) with the aim to create a new map of CBA from the Alpine-Carpathian area. Up to day published solutions, coming from the so-called „Slovak gravimetric school“ (e.g.: reambulation of gravimetric databases on the national level, calculation of near and distant topographic effects, regularized, transformations of potential fields, 3D complex density modelling with the introduction of the geological corrections, stripping of gravimetric fields) could be further developed and applied during the tectonic interpretation of the new CBA map from the Alpine-Carpathian region with the aim to improve the knowledge about Alpine orogenesis and its relation to the upper-mantle dynamics. As a part of the project, there are planned also verification field measurements, which can contribute to the improvement of the precision of the gravimetrical dataset of the Alpine- Carpathian area. Project has chance to develop the methodics of CBA calculation in high-mountains environment using the concept of ellipsoidal heights and to deliver to other experts an unique new gravimetric map from the region of Western and Central Europe. Main output of the project will be the new CBA map from the Alpine- Carpathian region in a digital format (grid 4x4 km), which will be provided for a realisation of gravimetric, geodynamic, exploration, geothermal and other studies and researches. Additional outputs of the project will be the transformed maps (grids) of CBA field. |
Radon activity concentration in selected show caves in Slovakia
Objemová aktivita radónu vo vybraných sprístupnených jaskyniach na Slovensku
Duration: | 1. 1. 2021 - 31. 12. 2024 |
Program: | VEGA |
Project leader: | Ing., RNDr. Smetanová Iveta PhD. |
Annotation: | The project addresses the investigation of radon activity concentration (222Rn) in the atmosphere of selected show caves in Slovakia, using integral and continuous measurements. Long-term integral and short-term continuous monitoring will be performed in the atmosphere of the Brestovská Cave, the Harmanecká Cave and the Demänovská jaskyňa slobody Cave. In the Važecká Cave the continuous monitoring of radon will continue. Periodic and non periodic variation of radon activity concentration will be evaluated in relation to the meteorological parameters measured inside and outside the cave. Radon activity concentration in water collected from lakes and streams in the above mentioned caves will be determined. On the basis of the obtained experimental data a model of seasonal, daily and short-term variations of radon in caves will be proposed and tested, as well as model of their ventilation regime. |
Response of Mountain pine to stress factors in mountain areas of the Western Carpathians
Odozva borovice horskej – kosodreviny na stresové faktory v horských oblastiach Západných Karpát
Duration: | 1. 1. 2021 - 31. 12. 2024 |
Program: | VEGA |
Project leader: | Ing. Lukasová Veronika PhD. |
Annotation: | The communities of Mountain pine (Pinus mugo) fulfill important ecological and environmental functions in mountainous areas. Due to climate changes, these communities are exposed to warming, extreme weather conditions (hot dry summers, warm spells in winters, reduced snow periods and snow cover) and high surface ozone (O3) concentrations, which affects their condition. The project presents a comprehensive approach to assess the biological response of P. mugo communities to stress factors (O3 concentration and bioclimatic conditions) evaluated by the normalized difference vegetation index (NDVI), oxidative stability (OxSt) and the visible injury index (VII) of assimilation organs. The use of NDVI derived from satellite data which reflects the amount of chlorophyll in plant tissues; provides the possibility to analyze the damage in a large scale. Presented project is highly topical and responds to the requirements of the European Commission for the conservation of biodiversity in the context of climate change. |

Variability of geomagnetic field in various time scales from the point of view of physical causes
Premenlivosť geomagnetického poľa v rôznych časových škálach z pohľadu fyzikálnych príčin
Duration: | 1. 1. 2021 - 31. 12. 2023 |
Program: | VEGA |
Project leader: | Mgr. Revallo Miloš PhD. |
Annotation: | The project is aimed at modelling of selected aspects of geomagnetism related to the variability of the Earth's magnetic field in various time scales. In the case of short time scales (hours, days), magnetic disturbances due to external influences, especially variable solar activity, will be investigated. In the case of long time scales, a partial task of the project will be the analysis of processes related to the internal sources of the magnetic field. Rapid time changes of the field are one of the manifestations of space weather, which can endanger present technological systems. Slow temporal changes of the field are the reason why its monitoring is necessary, especially for navigation purposes in aviation. The presented project is focused on solving partial problems related to a wider spectrum of variations of the Earth's magnetic field, with a physical view of the causes in connection with variable solar activity and also with the basic principles related to the generation processes of the field. |
Rifting and subsidence history of back-arc basins across the Western Carpathians
Rifting a subsidenčná história zaoblúkových paniev Západných Karpát
Duration: | 1. 1. 2021 - 31. 12. 2024 |
Program: | VEGA |
Project leader: | RNDr. Kotulová Júlia PhD. |
Annotation: | The project is focused on the research of subsidence history, mainly in the Danube and East Slovakian Neogene basins. Due to a plentiful newly published research results, a need to revise older models is now present. With regards to the the aims of this work, new biostratigraphic, radiometric and geochemical analyzes (organic carbon content, Rock-Eval pyrolysis, vitrinite reflectance, biomarkers) will be performed. They will be derived from key deep wells, outcrops and correlated by using available reflection seismic. The analysis of subsidence history will allow the determination of the total, tectonic and thermal history in connection with the geodynamic development of the Western Carpathians. The study will also bring new insights into the hydrocarbon and geothermal systems of the basins. The final refined tectono-thermal models will therefore be potentially applicable in various energy industry sectors. |
Amber cockroaches (III)
Šváby zo svetových jantárov III.
Duration: | 1. 1. 2022 - 31. 12. 2024 |
Program: | VEGA |
Project leader: | Mgr. Vršanský Peter PhD. |
Annotation: | Cockroaches are the most significant terrestrial fossils and their study in this agency terminated in two successful projects (one "excellent project" of the agency, referenced in Nature and also in Science, popularised 3x in title BBC). Project is summarising and studying about 4.000 amber cockroaches with most of them from the extremely rare ambers from time of dinosaurs. Unique study contributes to the knowledge of the amber source ecosystems (paleoecology, including the only reference point to the contemporary nature, the amber), detailed phylogenetical analysis (evolutionary patterns), functional morphology, anatomy (including gut content with endosymbionts and eggs) of Mesozoic animals including the sensorial systems, having no equivalent. The modest methods including synchrotron and newly developed ad-hoc optical methods are being used. |

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
Duration: | 1. 7. 2019 - 30. 6. 2023 |
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. |

Research on the influence of geological aspects on the estimation of seasonal correction factors of radon for living spaces
Výskum plyvu geologických aspektov na odhad sezónnych korekčných faktorov radónu pre pobytové priestory
Duration: | 1. 1. 2022 - 31. 12. 2025 |
Program: | VEGA |
Project leader: | Ing., RNDr. Smetanová Iveta PhD. |
Annotation: | The main source of radon in buildings is the subsoil. Radon concentration in the soil air is not constant and depends on several parameters. A proper understanding of the mechanisms of radon transport from soil to homes can help reduce the health risk of the population from radon exposure. Concentrations of 222Rn, 226Ra, 232Th, 40K in the soil will be monitored in order to gain new knowledge about their distribution in the soil and also contribute to a better understanding of radon exhalation from soil as a function of soils parameters. The research will also improve the sensitivity of 222Rn measurement methods. Models describing the entry of radon into buildings and radon behavior in residential areas will be improved and tested. Based on a year-long measurement of indoor 222Rn and knowledge of the subsoil, seasonal correction factors for the calculation of average annual indoor radon, depending on the geological aspects of the soils, will be proposed and adjusted. |
