Россия, Хабаровский край, долина реки Седьмая вторая. Кварцевый диорит. По всей видимости дайка. На геологической карте не обозначена. Возраст скорее всего - поздний мел. Мелкая равномерно рассеяная вкрапленность пирита.
Russia, Khabarovsk Territory, valley of the Seventh 2nd river. Quartz diorite. Most likely a dike. Not indicated on the geological map. The age is most likely late Cretaceous. Fine, evenly dispersed dissemination of pyrite.
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.
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.
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.
