Green granular Chamosite with individual crystals less than 1mm in most areas o fthe specimen. Chamosite is a phyllosilicate but not a mica, but is a member of the chlorite group with mica sheets. It is also the iron analogue of Chlorite. The chrystal chemistry of Chamosite thus gives way to a micaceous habit, just not in large sheets like a mica group mineral. Chamosite was named for Chamoson, Switzerland, where it was forst home.
