SOAPSTONE

Soapstone is massive Talc which occurs as a secondary mineral formed as a result of the alteration of olivine, pyroxene, and amphibole.

It occurs along faults in magnesium-rich rocks. It occurs less frequently as a result of thermal metamorphism of dolomitic limestone s.

It's distinguishing features are extreme softness, soapy feel, and greenish white colour. Because of its softness it has often been used for carving into artifacts such as figurines.
