Chlorite: Mineral description, properties and formation - Geology

Chlorite is a common mineral, found in metamorphic, igneous, and sedimentary rocks. It is an important rock-forming mineral in low- to medium-grade metamorphic rock formed by metamorphism of mafic or pelitic rock. It is also common in igneous rocks, usually as a secondary mineral, formed by alteration of mafic minerals such as biotite, hornblende, pyroxene, or garnet.
