Anorogenic granitoids of the Early Precambrian magmatism of the Ukrainian shield
The Early Precambrian magmatism of the Ukrainian shield evolved through regular changes in tectonic setting, composition and depth of formation of rocks of three magmatic associations: (1) granitic, (2) diorite-granitic and (3) anorthosite-granitic. They correspond to the S, I, A - gtanite types res...

| description | The Early Precambrian magmatism of the Ukrainian shield evolved through regular changes in tectonic setting, composition and depth of formation of rocks of three magmatic associations: (1) granitic, (2) diorite-granitic and (3) anorthosite-granitic. They correspond to the S, I, A - gtanite types respectively. The Early Proterozoic anorogenic granitoids of the Ukrainian shield are represented by the Korosten and Korsun-Novomirgorod rapakivi massifs, East-Peri-Asov complex of subalkaline granites, syenites and nepheline syenites, Perzhansk complex of subalkaline granites and rare-metal metasomatites. The anorogenic granitoids differ from magmatic rocks of the preceeding granitic and diorite-granitic associations by tectonic setting and composition. They are considered to belong to final stage of magmatic evolution and development of consolidated mature Early Proterozoic crust. The anorogenic granitoids of the Ukrainian shield are controlled by a major north-west linear magmatogenic structure, extending trough the whole Ukrainian shield to Poland. |
