Abstract
New results of U–Th–Pb isotopic dating of detrital zircon grains from the sandstones of the Upper Tauric Formation of the Crimean Mountains, belonging to the Lower Jurassic part of the Tauric Group, are presented. Comparison of the obtained age sets of detrital zircon grains with similar data for the clastic rocks of both lower and higher stratigraphic levels of the Cimmerides of the Crimean Mountains shows a significant difference between them. This reflects radical changes in the sources of sediment supply for the studied strata, which took place at the Triassic–Jurassic boundary and at the beginning of the Middle Jurassic. During the Late Triassic–Jurassic time, the sedimentary basins of the Crimean Mountains were formed directly on the southern (in present-day coordinates) continental margin of the East European segment of Eurasia. During the Late Triassic, the vast Scythian–Tauric megabasin was located here. Mostly shallow-water sediments accumulated in its northern part, in the Scythian sedimentary basin, and flysch deposition took place in its southern part, in the Tauric deep-water sedimentary basin. The clastic components of the flysch are dominated by the products of destruction of the crystalline basement complexes of the Sarmatian segment of the East European craton (EEC), the equivalents of the crystalline complexes exposed at present within the Ukrainian Shield and the Voronezh crystalline massif. The clastic material was supplied to the Tauric basin in transit via the Scythian basin. At the Late Triassic and Early Jurassic boundary, detrital material from the EEC ceased flowing into the Tauric sedimentary basin. But detrital material, the primary sources of which were the crystalline complexes of Gondwana and the peri-oceanic complexes of the Rheic and Paleo-Tethys oceans, started to flow into it. This means that the paleogeographic situation on the southern margin of the East European segment of Eurasia changed dramatically during the Early Jurassic. The Scythian–Tauric megabasin as it existed during the Late Triassic disappeared. The Dobrogea–Crimea Uplift emerged in its northern part (Scythian sedimentary basin). However, no significant changes in the depositional environment took place in its southern part (Tauric sedimentary basin). Deep-water flysch accumulation continued there during the Early Jurassic. This inherited sedimentary basin is hereinafter referred to as Late Tauric to emphasize the difference of its sedimentary fill from the fill of the Tauric basin. At the boundary of the Early and Middle Jurassic or at the very beginning of the Middle Jurassic, sediment accumulation ceased in the Late Tauric sedimentary basin, and the Upper Triassic and Lower Jurassic strata, successively accumulated in the Tauric and Late Tauric basins, underwent deformations. Later, the system of subbasins of the Crimean Mountains formed on the basement composed of these deformed complexes during the Middle and Late Jurassic. The clastic material that accumulated in the system of subbasins of the Crimean Mountains during the Middle and Late Jurassic was mostly of local (regional) origin, but a new source of detrital material, which supplied Permian–Triassic detrital zircon grains to these subbasins, appeared in addition.

Fieldwork and isotope analyses were supported by the Russian Foundation for Basic Research (project no. 19-05-00284). Data collection and analysis for the Black Sea–Balkan–Anatolia region were supported by the MegaGrant MON RF (project no. 075-15-2019-1883, Orogeny: Formation and Growth of Continents and Supercontinents). The processing of the primary results of isotope analyses and the preparation of the publication were carried out as part of the research program for the Academy of Engineering, People’s Friendship University of Russia (project “5-100,” recipient N.B. Kuznetsov).
