Sardinia, Gola di Gorropu. Upper Jurassic succession of Easern Sardinia. Bioclastic limestones, oolitic cherty limestones and mudstones, of littoral-cricalittoral environment, with algae, benthic foraminifer and nerineids. Alternatively: Dogger-Malm.
Sardinia, Cala Luna. Upper Jurassic succession of Easern Sardinia. Karst cave in the gorge wall. Bioclastic limestones, oolitic cherty limestones and mudstones, of littoral-cricalittoral environment, with algae, benthic foraminifer and nerineids. Alternatively: Dogger-Malm.
Russia, Amur region, Haikta river valley, Berezite gold mine. Granodiorites in a pit wall with lamproite dikes (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.
