nsaussuriteA fine-grained compact mineral of a white, gray, or green color. It has a specific gravity above 3, and in part is identical with zoisite; in many cases it can be shown to have been derived from the alteration of feldspar. It is found in the Alps at various points as a constituent of the rock gabbro (including euphotide), and also at other localities.
