Explanation
It is also called blue diorite schist. A low-temperature high-pressure regional metamorphic rock. Blue green, fine-grained, fibrous balastic texture, porphyritic balastic texture, schistose structure. The main minerals are glaucophane, and other minerals are andalusite, aragonite, albite feldspar, chlorite, phengite, actinolite, hard chlorite, hard chlorite, chlorite or epidote. The rock type and mineral composition are closely related to the original rock: epidote and chlorite are abundant in the basic volcanic rock; From greywacke to sodium rich feldspar, quartze and siliceous muscovite; The chert metamorphist is rich in quartze. glaucophane schist is often associated with green schist and eclogite.
