Chlorite

 

This mineral occurs within a great range of compositions and is considered a group. It is characterized by its green color, micaceous habit, and cleavage, but its sheets are not elastic. It is a common mineral formed from alteration during low grade metamorphism. The name is derived from a Greek word meaning “green,” in allusion to the common color of the mineral.
