massive texture

Russia, Khabarovsk Territory, river valley Ko. Grandiorite massif. Bachelazskiy complex. Granodiorites are medium-grained, gray. Consist: plagioclase - 37-54%, K-spar - 8-27%, quartz - 18-30%, biotite - 8-13%, hornblende - 4-12%. Accessory minerals: magnetite, apatite, ortit, zircon, monazite. Massive texture. Hypidiomorphic grain structure. Upper Cretaceous. Definitions of absolute age: 86-103 million years.

Dyke granodiorite porphyry. Sikhote-Alin series of Eocene subintrusions. Eocene. The dyke has a length of about 800 m. The maximum thickness is 150 m. It has a submeridional strike (Az. 350 degrees). Az pad. 80 degrees. Angle of 70-80 degrees. Wedges out on both flanks splitting into several small bodies. Pledged by a series of faults, traceable after wedging out of the dyke in siltstones. In the upper part, granodiorites are intensively weathered to a completely disintegrated weathering crust.

Medium fine-grained biotite-pyroxene gabbro-diorite. Pluton. Sikhote-Alin series of Eocene subintrusions. Eocene. Massive texture. Consist: plagioclase 60-65%, clinopyroxene - 15–20%, hornblende - 1-5%, biotite - 10-15%. Accessory: apatite. νδ₽₂
