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.
