Peri-Gondwanan Blocks in the Structure of the Southern and Southeastern Framing of the East European Platform

Synthesis of the results of U–Pb dating of detrital zircons (dZr) from the Uppermost Precambrian–Phanerozoic strata of the southern and southeastern framing of the East European Platform (EEP), the Uppermost Precambrian and Cambrian–Ordovician strata of the Southern Urals, Ordovician strata of the Cis-Caspian Sea region and Jurassic coarse strata, and Upper Triassic flysch strata of the Crimean Mountains is presented. The spectra of U‒Pb ages of detrital zircons from the above objects were correlated with similar dates obtained for sandstones of the Uppermost Precambrian and Cambrian–Ordovician strata participating in the structure of peri-Gondwanan terranes. It was shown that the belt of peri-Gondwanan terranes, known in the northern Appalachians, Western and Central Europe, Middle East, Northern Africa, and Arabia, stretches into the northern part of the Cis-Black Sea region, the Cis-Caucasus, and Cis-Caspian Sea regions, forming the basements of the epi-Paleozoic Scythian and Turan platforms, and is traced further eastward up to the Southern Transuralian region, being involved into the structure of the Paleozoids of the Southern Urals.
