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.

Multiphase solid inclusions in orogenic peridotites as tracers of metasomatism in collisional orogens
Orogenic peridotites exposed in UHP terranes in collisional orogens record metasomatism by
fluids derived from the subducting slab. Multiphase solid inclusions (MSI) trapped in their peak
minerals, mostly garnet, provide information on physical and chemical composition of these
deep fluids. We focus on MSI in garnet peridotites and pyroxenites in the Variscan Bohemian
Massif to test the hypothesis that mantle metasomatism in hot UHP terranes is a multiphase
process, linked to crystallization of percolating melts of mixed crust-mantle origin. To achieve
that, we will reconstruct bulk chemical composition of MSI. We will also use high-resolution
analytical techniques to specify chemical composition of MSI constituents (silicates, graphite,
carbonates, apatite) including trace elements and C, O, Cl, resp. Sr isotope composition as
proxies for distinction of the source of metasomatizing agents. P-T-t constraints on formation
and metasomatism of peridotites will be provided using thermodynamic modelling and Lu-Hf
and in-situ dating (U-Pb garnet, U-Th-Pb Th,U-bearing phases).

Synthetic platinum-group minerals and their applications
Synthetic analogues of platinum-group minerals (PGM) will be experimentally studied in series
based on PGE carrier and according to principal ligands. A detailed crystallographic
investigation will be given to PGM with stoichiometry 1:1:1. Most abundant Pd-dominant
minerals (e.g. kotuskite PdTe) will be studied in terms of other element carriers (Ag, Bi, Cu, Sb,
Sn, Se, etc.) and its solubility dependence on temperature. PGM will be investigated in terms of
chemical and physical properties, crystal structure and thermal stability. The results should help
the understanding of formation of PGM assemblages in nature and their finding and processing.
Compounds of jacutingaite-family will be synthetised and studied in terms of their specific
properties with application to material science. Structural, thermodynamic and electronic
properties of PGM that can be considered as 2D materials will be studied. The detail knowledge
of physical properties will help to predict their potential application in new nanotechnologies.

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.

Petrogenesis and emplacement of deep-marine alkaline basaltoids: a case of Early Cretaceous magmatism in the northern Tethys region
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.

EuroGEO Showcases: Applications Powered by Europe
The Group on Earth Observation (GEO) is a partnership of 105 national governments, the European Commission and 127 participating organizations. GEO implements a Global Earth Observation System of Systems (GEOSS) and envisions a future where decisions and actions for the benefit of humankind are informed by coordinated, comprehensive and sustained Earth observations.
The EuroGEOSS initiative is the European regional GEO and will represent the European Caucus within GEO.
The EuroGEOSS vision is to significantly increase the benefits for Europe regarding its participation within GEO through improving user uptake of the data GEO assets generate and by harvesting the environmental information produced through the GEO flagships and initiatives. In this context, e-shape is funded by the European Commission in support of EuroGEO.

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.
