Abstract

Two-mica granites are widespread in the Belomorian Belt but are not abundant. These rocks are typically restricted to aluminous kyanite–garnet–biotite and garnet–biotite plagiogneisses. In Mount Rikolatva on the southwestern Kola Peninsula, two-mica granites and migmatites compose the neosome of a large agmatite structure, whose fragment is shown in Fig. 1. In outcrops, the granites are fine-grained vaguely schistose or massive rocks, often with skialiths of plagiogneisses. In our earlier publications [1, 2], we considered the granTwo-Mica Granites in Northwestern Belomorie: Genesis of the Rocks and Rb–Sr Dating of the Granitization Process
