Russia, Primorsky Territory, Mount Pidan. Granodiorite massif. The massif has the shape of an oval elongated in a sub-latitudinal direction. Area 80 km square. Contacts with host rocks - 60-90 degrees. Granodiorites biotite-hornblende, gray, dark gray, medium-grained, fine-grained. Consist: plagioclase 50-60%, quartz 10-15%, orthoclase up to 10%, biotite 10-12%, hornblende 5-15%. Accessory: apatite, zircon, rarely orthite. Upper Cretaceous.
Russia, Khabarovsk Territory. Stock diorite porphyrites. Butakano-Churkinsky complex. Greenish-gray and dark gray with a greenish tint porphyry rocks with a different number of plagioclase phenocrysts in the microcrystalline bulk consisting of a plagioclase sheet, chlorinated biotite flakes and hornblende. Plagioclase phenocrysts are represented by zonal andesine tablets, sometimes albitized along cracks. The hornblende, also present in phenocrysts, is represented by idiomorphic grains 1 × 2.5 mm in size. In the second photo, magnification * 10. Upper Cretaceous.
