GEOCHEMICAL FEATURES AND GENESIS OF PALEOPROTEROZOIC PLAGIOGRANITOIDS OF CENTRAL AZOV REGION (UKRAINIAN SHIELD)

Language: Russian

Mineralogical Journal 2016, 38 (1): 73-83

Abstract: The Azov megablock is deeply transformed in the Paleoproterozoic Archean craton. Paleoproterozoic granitoids play important role in its structure. The earliest of them are plagiogranitoids of Karatyuk complex (2.13 ± 0.04 Ga), and later ones — the potassic granitoids of Anadol and Saltych complexes (2.08—2.09 Ga). Geochemical studies of Paleoproterozoic plagiogranitoids of the Karatyuk complex of Central Azov region have been performed. According to the geochemical data, they are of juvenile genesis and formed during partial melting of metabasites in the mantle- and lower crustal magmatic sources. By geochemical characteristics they correspond to high-SiO2 adakites. Formation of Paleoproterozoic intrusion of plagiogranitoids of the Karatyuk complex of Central Azov region may be associated with the processes of subduction at the boundaries of the Sarmatian microcontinent.

Keywords: Paleoproterozoic, plagiogranites, Central Azov region, Mangush synclinorium, Karatyuk complex, Sarmatian microcontinent, adakite, Usman complex.
