Abstract U–Pb dating and Hf isotopic analyses of detrital zircon grains from Cambrian-Devonian strata in the Moroccan Mesetas were undertaken order to constrain its Paleozoic paleogeographic evolution. In this work, we analyzed 12 Late Devonian-Late Carboniferous samples syn-collisional rocks Western Eastern Mesetas. All our present significant Ediacaran (ca. 620 Ma) Rhyacian 2.1 Ga) population...
The study evaluates the geothermal energy potential of two depleted oil and gas reservoirs representing different lithostratigraphic formations—the carbonate formation Visean age from basement Carpathian Flysch Rotliegend sandstone Eastern part Foresudetic Monocline, Poland. Advanced modeling techniques were employed to analyze studied formations’ heat, storage, transport properties. obtained r...
Based on new structural, petrological and U-Th-Pb geochronological data, a reappraisal of the Variscan tectono-metamorphic history Pelvoux Massif (External Crystalline Massif, French Alps) is proposed with aim to understand flow pattern kinematics partially molten crust Eastern Shear Zone. The consists high-grade metamorphic rocks middle lower crust, mostly migmatites, that record prominent syn...
In orogens, pinpointing the timing of mineralization is often complex due to superimposition magmatic, metamorphic and tectonic events. Unravelling tectono-metamorphic evolution deformed terranes essential for understanding formation orogenic mineralization. Bossòst dome Pyrenean Axial Zone, undated stratabound Pb-Zn previously considered be SEDEX-like devoid evidence significant remobilization...
Abstract The Finnmark Platform Composite Tectono-Sedimentary Element (CTSE), located in the southern Barents Sea, is a northward-dipping monoclinal structural unit. It covers most of Norwegian Sea where it borders mainland. Except for different age basement, CTSE extends eastwards into Kola Monocline on Russian part Sea. general water depth varies between 200 and 350 m, sea bottom influenced by...
