Did the West-Gondwana orogens form by inversion of long-lived rift domains?

This project suggests a study of an early convergent evolution of the Kaoko–Dom Feliciano–Gariep orogenic system exposed in Namibia, Uruguay and Brazil. Previous study has suggested that the pre-collisional evolution of that system was represented by ca. 200 My of rifting, and that inversion of the rift domain took place soon after the break-up, i.e. probably without the development of a large-scale oceanic domain that could be subsequently subducted. The study will focus on conditions of early collision and associated magmatism in the Kaoko and Dom Feliciano belts. It is subdivided into three sub-projects: a) tectonic evolution of the internal part of the Kaoko–Dom Feliciano–Gariep orogen; b) tectonic evolution of the western foreland in the Dom Feliciano Belt and c) igneous activity during early stages of the convergent evolution. The project will answer the question whether the early convergent evolution of the studied orogenic system is compatible with the presence of a subduction zone, or if the system is an inverted rift domain without major intervention of oceanic crust.

Petrogenesis of (ultra-)potassic magmas in the European Variscides – implications for development of collisional orogens and crustal growth models

Deep subduction and relamination of felsic continental crust rich in radiogenic elements have far-reaching consequences for the thermal state and rheology of the orogenic lithosphere as well as mantle enrichment processes. The project proposes an integrated study of petrology, geochemistry and Sr–Nd–Pb–Li–O–Mg–Cr isotopic systems in Early Carboniferous ultrapotassic plutons, related to deep subduction of continental crust, in Bohemian Massif, French Massif Central and Vosges. This study should provide pivotal information about mantle and crustal sources of parental magmas in the Variscan orogenic root (Moldanubian Zone) and their further evolution. In turn, these data represent a key input into any large-scale model aimed at explaining the geotectonic development of the European crust and lithospheric mantle. More importantly, the proposed research should improve our understanding of the nature and genesis of ultrapotassic magmas with peculiarly mixed mantle–crustal signatures, as well as the general geotectonic development of younger collisional orogens, e.g. Andes or Himalayas.

Element transfer in deep subduction environment: constraints from ultrahigh-presssure metamorphic terranes

Ultrahigh-pressure (UHP) terranes of the Bohemian Massif (BM) include ultramafic and mafic UHP rocks closely associated with the diamond-bearing UHP metamorphic rocks. Similar peak conditions of c. 1100°C and c. 5 GPa in some of these terranes and petrological evidence indicate that the mantle and the crustal rocks shared at least part of their subduction history. Our aim is to investigate multiphase solid inclusions (MSI) in ultramafic and mafic rocks and test the hypothesis that they formed through interaction of the fluids/melts derived from deeply subducted continental slab and the overlying mantle. Major and trace element composition of the MSI and C and O isotope composition of their minerals will provide information on the source of the trapped fluid and thus contribute to understanding of element recycling in deep subduction zones. The refined P-T conditions obtained from the MSI study and newly acquired Lu-Hf geochronological data for the ultramafic and mafic rocks will be used to precise depth and temperature reached during subduction and its timing.

Principal mechanisms of peripheral continental growth during supercontinent cycle

The growth of eastern Pangea involves three contrasting orogenic cycles: 1) Baikalian cycle (570-540 Ma) consists of accretion of peri-Rodinian continental, Mirovoi and Panthalassan oceanic fragments to the Siberian margin followed by extensional HT reworking, the growth of magmatic arc, giant accretionary wedge and intraoceanic basin. 2) Altai cycle is typified by crustal thickening followed by syn-extensional melting of the accretionary wedge (420-380 Ma) and the opening of Mongol-Okhotsk ocean. Cycle terminates by the growth of migmatites domes (370-340 Ma), thrusting of intraoceanic ophiolites and relamination of molten material beneath oceanic crust. 3) Paleotethysian cycle (300-220 Ma) is represented by oroclinal buckling of the hybrid oceanic lithosphere. The Baikalian cycle is related to advances and retreats of Panthalassa ocean. Altai cycle results from dynamically advancing and retreating subduction of young and hot Rheic type ocean beneath Pacific one. This hot, weak and hybrid lithospheric segment was shortened and incorporated into Pangea supercontinent.

Granulite–migmatite domes - insights to Devonian and Carboniferous evolution in the Variscan belt

We aim to study and compare various aspects that are related to exhumation of deeply buried felsic rocks that form now Devonian and Carboniferous granulite-migmatite domes in the Variscan belt and contributed thus to large-scale crustal differentiation. The role of melting on the rheological weakening of the rocks is known for a long time, but differences of the melting processes of metasedimentary rocks and granitoid rocks, with respect to fluid-present, dehydration and fluid-fluxed melting and relation to the P-T path of the rocks are rarely studied simultaneously. These relations influence when and where melting – and therefore rheological weakening occurs, and how buoyancy changes, and are likely to explain differences in Devonian and Carboniferous orogenic processes in terms of timing and location of the exhumation of granulite-migmatite domes. We already identified granulite-migmatite domes exhumed at different time, with contrasting lithologies, and likely exhibiting contrasting melting processes – which allows such comparative study.

The role of inherited continental margin architecture on early Variscon convergence

It is well known that the inherited architecture of continental margins determines subsequent collisional processes and the resulting structure of collisional mountain ranges. Classic hyper-extended Atlantic-type continental margins differ fundamentally from thinned West-Pacific-type margins, which are characterized by massive crustal melting, intrusions of large volumes of mafic magmas, and HT-LP metamorphosis. In this project, we propose that the Pacific-type hot continental margin became established along the northern margin of Gondwana during the Ordovician and was subsequently incorporated into the Devonian subduction-collision orogenic wedge preserved on the western margin of the Bohemian Massif. This project will use a multidisciplinary approach combining geological and geophysical methods to characterise the architecture of this specific orogenic system. Furthermore, a development scenario will be proposed and tested by numerical modelling, with a view to fundamentally changing the current view on the evolution of the European Variscan Belt.

Evolution and post-emplacement history of carbonatites: Implications for the mobility and concentration of critical metals

Carbonatites are rare igneous, carbonate-rich rocks derived from the Earth’s upper mantle. They are important because of their associated rare-metal mineralization. Rare metals, such as REE, Nb, Ta, Zr, Th and U, are initially concentrated early in the evolution of carbonatitic magma to form primary mineralization. The behavior of these metals during deformation and metasomatic processes (a series of textural, chemical and mineralogical changes of REE mineralization) is one significant aspect of carbonatite petrogenesis that has direct implications for the economic potential of these rocks. A significant number of carbonatites were emplaced in tectonically active settings, where they were subjected to metamorphism and underwent a series of changes affecting the distribution of REE, Nb and other rare metals in the host rock.This project challenges us to study evolution of carbonatites in order to better understand the factors that controls late-stage element fractionation effects of subsolidus processes on redistribution of rare metals.

Leading edge instrumental methods in high resolution global Jurassic-Cretaceous boundary correlations

The conceptual approach of proposed research comprises (1) acquisition and evaluation of new geochemical data for the global definition of the Jurassic-Cretaceous boundary in marine environment, (2) their integration with high-resolution magnetostratigraphy, biostratigraphy and sedimentology, and (3) correlation of new and previously studied sections in the multi-proxy mode. The integrated-stratigraphy database will be created. Classic key-sections, such as Kurovice (Czech Republic) and Brodno (Slovakia) will be supplemented by new sections: Snežnica (Slovakia), Rettenbacher (Austria), Silesian Unit (Goleszow - Poland) and Golubac (Serbia). The research will be carried out in cooperation with the International Subcommission on Cretaceous Stratigraphy.

'Petrogeneze těšínitových hornin na Moravě a ve Slezsku: spodně křídový magmatismus severní Tethydy a stopování rané fáze plášťového chocholu CEVP'

Early Cretaceous sequences in Silesian napes of Outer Carpathians in Czech Republic and Poland comprise bodies of submarine volcanic and subvolcanic rocks of the teschenite rock association. Such low volume systems of alkali rocks emplaced in deep-marine settings not related to formation of ocean-island are exposed rather scarcely worldwide. The project focuses on their petrogenesis and tectonic setting. The main petrogenetic questions will be solved using isotope geochemistry (Sr-Nd-Pb-Li) and geochronology (U-Pb, apatite, calcite), mineralogy, petrology, volcanology and sedimentary geology. With respect to significant post-magmatic alterations, the isotopic systems will be analysed on separated fractions of stable primary minerals (olivine, pyroxene, apatite, titanite). The obtained data will contribute to the discussion of mineral-phases stability during submarine metasomatism. Besides the petrogenesis, the project will focus also on stratigraphic range and eruptive style of teschenite rocks. The revision of modal composition will result in revision of their classification.

Palaeogeographic Maps of Permian Continental Basins of Central Europe

The Middle Sudeten Trench is one of the largest geological structures in the Sudetenland. Its geological diversity creates a unique opportunity for research projects. The uniqueness of the sediments of the Middle Sudeten Basin is evidenced by the fact that it is one of the richest sites in the world for preserved traces of Early Permian tetrapods. In view of this, it is necessary to carry out a comprehensive paleoenvironmental analysis based on modern research methods. The intention of the project is to unify and update the stratigraphic schemes of the Permian. The project aims to unify and update the stratigraphic schemes of the Permian in the Middle Sudeten Basin based on the traces and fossils found and their comparative analysis. Studies will include sedimentological, geochemical and innovative methods, and geochronological, paleoecological and paleoenvironmental studies will be conducted. The project will contribute to the preparation of palaeogeographical maps of the Permian terrestrial basins of Central Europe.

Ensuring Sustainable Land Management in Selected Areas of Ethiopia on the Basis of Geoscientific Mapping

The main objective of the project (2019-2023) is to eliminate the degradation of agricultural land and its restoration, as well as to promote the diversity of nature according to the UN Sustainable Development Goals. The achievement of these objectives is based on the generation of comprehensive information that will lead to the production of a set of geoscientific maps and detailed spatial/landscape plans in key areas of southern Ethiopia (Sidama region, Gedeo zone and Gamo zone of SNNPR). These outputs will enable the analysis of adverse geological phenomena (e.g. volcanic eruptions and seismic tremors, landslides and rockfalls, earth fissures, etc.) and will also contribute to the efficient and sustainable use of natural resources (groundwater, soil and minerals). The project also aims to develop the professional capacities of a wide range of experts in geoscientific mapping, pedology and the preparation of land use/landscape plans. In 2020, field geological, pedological and hydrogeological mapping of the Sidama and Gedeo area was completed and mapping outputs are currently being produced.

Geological and hydrogeological map compilation on a 1:1 000 000 scale for the entire terittory of Ethiopia

The main objective of the project (2020-2023) is to compile a national geological and hydrogeological map of Ethiopia at a scale of 1:1,000,000. These map outputs will help in addressing the acute increase in demand for potable water supply and for other practical purposes in various industrial sectors and building national infrastructure and sustainable agriculture. In addition, the capacity of professionals and government officials in the practical use of geoscience information will be enhanced. Furthermore, an interactive online mapping system will be developed so that the map outputs are freely accessible to all those interested in the use of geoscience data. The focus of activities in 2020 was the creation of a new topographic basis for the processing of map outputs, reinterpretation of geophysical and remote sensing data, creation of a new geological legend, regional geological zoning and stratigraphy.
