The subsequent crustal deformations that accompanied the formation of the Kirovogradsky, Lelekovsky, Subbotsk-Moshorinsky and other fault zones, as well as the Korsun-Novomirgorod pluton of gabbro-anorthosites and rapakivi-like granites were reflected in the structure of the massif. A detailed study of the Novoukrainian massif and its frame made it possible to establish the chronological sequence of stages and phases of deformation of the central part of the USh from the Archean to the Late Proterozoic. |
