Description
A group of green silicate minerals containing aluminum, iron, and magnesium. Members of the chlorite group include chamosite, clinochlore, nimite, alushtite, and penninite. Chlorite is a soft, mica type mineral that occurs in irregular foliated masses. It has been found in Egypt, Middle East, western Asia, and the U.S. (New York, California). The opaque, flaky mineral was used in antiquity for seals and small decorative items.
