The Paleoarchean and Mesoarchean TTGs of the western Azov area, the Ukrainian Shield

A large anticline structure occurs in the western part of Azov Domain Ukrainian Shield. It is composed rocks Mesoarchean (3.2-3.0 Ga) granite-greenstone association and relics an older basement. The divided into two parts by Bilotserkivka sub-latitudinal strike. northern includes Huliaipole Remivka blocks, southern comprises Saltycha anticline. U-Pb age plagiogneisses Lantsevo 3299 ± 11 Ma. In terms geochemical characteristics, they correspond to TTGs. structure, we previously identified quartz diorites having 3297 22 These data show that represents ancient Dislocated trondhjemites were studied Ivanivka area at eastern They contain numerous heavily altered amphibolites. zircons from trondhjemite 3013 15 are same as TTGs Shevchenko Complex cutting through sedimentary- volcanogenic greenstone structures Domain. share characteristics with biotite amphibole-biotite gneisses “Kainkulak beds” Zrazkove village located Mokra Konka river (3.1-3.0 lower reaches Kainkulak (2.92 Ga). Thus, actually represent Complex, transformed Paleoproterozoic time due dislocation metamorphism. late Paleoarchean (3.3 tonalites known West KMA domains; probably also occur basement Middle Dnieper domains, where detrital this have been reported. allow us assume existence a Late protocraton, which belts Shield formed.
