Russia, Perm region, Saranovskoe chromite deposit. Saranovskiy chromite-bearing gabbro-peridotite massif. Possesses large reserves of chromite ores. The outcropping area of ultrabasic rocks is only 0.22 km2, with a length of 1700-1800 m and a width of about 200 m. The maximum width of the massif in the middle part, including gabbroids, is about 400 m. Its strike is submeridional (0-345 °).
Russia, Khabarovsk Territory, village Krasnoselskoye. Pyroxene-olivine, olivine basalts. Form a cover. Gray, with a violet hue, dark gray, porous, with a porphyry structure. Phenocrysts are represented by: labrador, olivine, augite, hyperstene. Size from 0.5-1 to 2-3 mm. Epidote and chlorite are formed on pyroxenes. Iddingsite develops on olivine. The pores are usually filled with calcite, zeolites, chlorite and epidote. The age of the rocks is 15 million years. Kizinskaya series.

Russia, Subpolar Ural, Kozhim river valley. White, light gray marbled limestones. Include microlayers of quartz-mica composition, the content of quartz grains in them sometimes reaches 30–35%. Under the microscope of the rock, a granoblastic structure with relics of an uneven-grained - blastopsammite and blastoaleurite is found; layered, banded texture and consist of a calcite heterogeneous aggregate (70–99%) with intercalations of quartz grains (up to 25%) and microlayers of carbonaceous-chlorite-sericite, muscovite-chlorite composition.
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.
