A semi-crystalline Talc crust rests on the pale gray limestone base of this hand specimen. The Talc has no definite crystal form, but shows obvious crystalline tendencies. It closely resembles mica in both its platy form, green color and pearly luster. It is essentially translucent, though some sections are thin enough to show definite transparence.
