Granodiorite

Rock type: 
Age:

Russia, Khabarovsk Territory, river valley Ko. Grandiorite massif. Bachelazskiy complex. Granodiorites are medium-grained, gray. Consist: plagioclase - 37-54%, K-spar - 8-27%, quartz - 18-30%, biotite - 8-13%, hornblende - 4-12%. Accessory minerals: magnetite, apatite, ortit, zircon, monazite. Massive texture. Hypidiomorphic grain structure. Upper Cretaceous. Definitions of absolute age: 86-103 million years.

Russia, Amur region, Kolbachi Creek Valley. Contact granodiorites (light) and lamproite dike (dark). Porphyry biotite-hornblende granodiorites. Granodiorites form a large Haiktinsky massif. A characteristic feature of granodiorites is the greenish color of plagioclase and the rocks themselves, due to the processes of chlorination, epidotization and carbonatization, accompanied by co-securitization and seritization of plagioclase. Pozdnestanovoy complex. Paleoproterozoic. Lamproite dike - the third phase of the Amujikan complex. Upper Jurassic.

Russia, Amur region, Haikta river valley, Berezite gold mine. Porphyry biotite-hornblende granodiorites. Granodiorites form a large Haiktinsky massif. A characteristic feature of granodiorites is the greenish color of plagioclase and the rocks themselves, due to the processes of chlorination, epidotization and carbonatization, accompanied by co-securitization and seritization of plagioclase. Pozdnestanovoy complex.

Russia, Khabarovsk Territory. Granodiorite biotite-hornblende, fine-grained, medium-grained. Butakano-Churkinsky complex, second phase. Upper Cretaceous.

Rock type: 
Age: 
75 millions years

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.
