Abstract

Granites with monzonitic structure and granosienites represent early and late phases of intrusion development. Crystallization of granites takes place with deanortitization of plagioclase and incongruent formation of К-Na-feldspar. Granosienites are characterized with cotectic crystallization. Changes in granosienites at the acid stage lead to albitization of the K-Na-feldspar, chloritization of biotite and large-scale development of pyrite with Cu, Cd, Zn, Pb impurities. The late alkaline stage is characterized with sedimentation of Ca as calci-spar.
