Eocene

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

Gabbro-diorite pluton. Sikhote-Alin series of Eocene subintrusions. Eocene. Massive texture. Consist: plagioclase - 55-60%, clinopyroxene - 15–20%, hornblende - 10-15%, biotite - 5-10%, quartz - 1–5%. Accessory: apatite. νδ₽₂

Dyke diorite porphyrite. Sikhote-Alin series of Eocene subintrusions. Eocene. The thickness of the dikes varies from 1 to 20 m, sometimes reaching 70 m, the length rarely exceeds 500 m. The studied contacts of the dikes have steep angles (70-80 degrees) of incidence, and contact alteration are expressed in weak keratinization of rocks to a width of 5-10 cm. Consist: phenocrysts 20-25% - plagioclase, hornblende; the bulk 75-80% - plagioclase 30-35%, dark-colored mineral (hornblende?) 15-20%, quartz up to 1%. Accessory: apatite, sphene. δπ₽₂
