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.
