Chlorite Schist

Chlorite schist is a metamorphic rock primarily composed of chlorite minerals. It is characterized by its foliated texture, meaning the minerals are aligned in parallel layers or planes, giving the rock a distinct schistosity. The presence of chlorite imparts a green color to the rock, though other colors may be present depending on the impurities. Chlorite schist forms under relatively low-grade metamorphic conditions, often from the alteration of other rocks like shale, basalt, or volcanic ash. The rock's appearance can vary, with some specimens displaying a well-defined schistosity and others appearing more massive.
