It is determined, that two-feldspar granites of the Vishnevoe massif of the Slavgorod block are the most ancient crustal granites in the Middle-Dnieper granite-greenstone terrane. Their isotopic age for monazite — 2985 Ma. They are close in age with enderbites of the Slavgorod complex (3014 ± 7 Ma) and granodiorites of the Dnieper complex (2972 ± 6 Ma) on the Slavgorod block, indicating their formation within a short time interval, probably as a result of the plume rise about 3000 Ma ago. Plagiogranitoids were formed by the partial melting of a mafic source, and two-feldspar granites by the partial melting of the older gneiss basement.
