Granite

Russia, Khabarovsk Territory, Yagdynya river. Biotite Granites. Form an massif of 850 square kilometers. Consist: oligolclase - 24-32%, microcline - 24-45%, quartz - 15-29%, biotite - 4-11%. Plagioclase forms sericite and albite (auto-metasomatism). Chlorite is formed by biotite. Accessory: sphene, zircon, apatite. Definitions of absolute age (K): 207, 230, 235 million years. Upper Triassic.
