WebThe Kainuu schist belt has been deformed and metamorphosed under greenschist to middle-amphibolite facies (garnet-staurolite-kyanite) conditions (Korsman and Glebovitsky, 1999). In the Talvivaara area, almandine garnet, staurolite, chlorite, biotite, and in some samples, also late cordierite are common minerals in aluminous pelites. WebWikipedia

WebBy lithologic criteria, the Main Central Thrust is defined as the boundary between quartzite and phyllite, from the Lesser Himalayan Sequence; and the orthogneiss biotite-rich schist, which belongs to the Greater Himalayan Crystalline complex. By metamorphic isograd, the Main Central Thrust follows the kyanite isograd. Under this criterion ... WebKyanite is a blue to light-green, triclinic mineral that occurs in long, thin-bladed crystals and crystalline aggregates in gneiss, schist, and pegmatites.
