Chlorite Mineral description, properties and formation

Recognizing a mineral as a member of the chlorite group is usually easy. However, placing a specific name on it can be difficult. Detailed optical, chemical, or x ray analysis is usually required for positive identification. The name quot;chloritequot; is often used in classrooms and the field because the minerals are difficult or impossible to identify.
