U-Pb LA-ICP-MS AGE OF DETRITAL ZIRCON FROM THE HLEYUVATKA SUITE OF KRYVBAS (THE UKRAINIAN SHIELD)

U-Pb LA-ICP-MS AGE OF DETRITAL ZIRCON FROM THE HLEYUVATKA SUITE OF KRYVBAS (THE UKRAINIAN SHIELD)

The 3.1-3.0 Ga tonalite-trondhjemite-granodiorite rocks of the Middle Dnieper craton were exposed in the provenance of meta-terrigenous rocks of the Hleyuvatka Suite, which forms the upper part of the Krіvоi Rog-Kremenchuk structure. In addition, 3,2; 3,3-3,4 and 3,5-3,7 Ga gneisses were also presen...

Description
Summary:The 3.1-3.0 Ga tonalite-trondhjemite-granodiorite rocks of the Middle Dnieper craton were exposed in the provenance of meta-terrigenous rocks of the Hleyuvatka Suite, which forms the upper part of the Krіvоi Rog-Kremenchuk structure. In addition, 3,2; 3,3-3,4 and 3,5-3,7 Ga gneisses were also present in the source area as well as the 2,87-2,85 Ga potassium-sodium granites. Among the Paleoproterozoic detrital zircons, five grains yielded an age of 2,14-2,09 Ga, which indicates the presence of Paleoproterozoic granites in the provenance. The maximum depositional age of the metamorphosed terrigenous rocks of the Hleyuvatka Suite is thus about 2,1 Ga. These data gives ground to distinquish the Hdantsivska and Hleyuvatka suites as a separate Series .
