lamproite

Rock type: 
Age: 
153 millions 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.

Rock type: 
Age: 
300 millions years

Spain, Catalonia, Carrer Josep Ensesa. Episienites (the last phase of granodiorites, extremely depleted of quartz). Black dyke - lamproite. Upper Carboniferous - Low Permian.

Spain, Catalonia, Platja d'Aro. On the right is granodioorite porphyry. Left (reddish) - Episienites (the last phase of granodiorites, extremely depleted of quartz). Black dyke (right) - lamproite. Upper Carboniferous - Low Permian.

Spain, Catalonia, Carrer Josep Ensesa. On the left is granodioorite porphyry. On the right  and first plan (reddish) -  Episienites (the last phase of granodiorites, extremely depleted of quartz). Black dyke - I'm not sure, I read what it is tonalitic porphyry.... Big doubt. Maybe lamproite. Upper Carboniferous - Low Permian.
