Form a cover. Porous olivine, pyroxene-olivine basalts and basaltic andesites. Olivine forms idiomorphic crystals 0.2-1.5 mm in size, partially or completely replaced by iddingsite, rhombic pyroxene is in the form of tabular grains 0.5-1.5 mm in size. The age of the rocks is 15 million years. Sovgavanskaya series. Pliocene.

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.
