CLINOZOISITE



Clinozoisite, a calcium aluminum silicate hydroxide mineral of the epidote group, is largely unstudied. It was reported from Franklin by Palache (1928a), but that material was later shown by Bauer and Berman (1930) to be chlorophoenicite. It was subsequently found in 1981 on the 1400 level in the Sterling Mine occurring as a green massive mineral, associated with amphibole, titanite, calcite, diopside, and a possible hydromica. Later that year it was again encountered at Sterling Hill, in the 935 stope, on the 500 level, as a pale violet mixture of clinozoisite and plagioclase, associated with diopside and calcite. There are no detailed studies of these occurrences. (Dunn, 1995)
