Russia, Khabarovsk Territory, village Sarapulskoye. The first and second photo, top-down: quaternary clay, sand, loam; basalt weathering crust; pillow lava; the lowest rocks are basalts. They are in the third photo. 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.

Russia, Magadan region, left side of the Duck river. Quartz-albite diorite porphyrite with quartz-albite veins. These are the famous Ducks dykes. Dyke №7. The dyke is a slab-like body with a capacity of 0.5 m in the East to 3.5 m in the West, accompanied by apophyses that run parallel to the sedimentary rocks (lower Jurassic siltstone). It is traced to a depth of 250 meters. Xenoliths are rare. Sometimes there are intersecting, until the disappearance of dykes.
