| Species: | Clinozoisite |
| Formula: | (CaCa)(AlAlAl)O[Si2O7][SiO4](OH) |
| Formation: | Secondary |
| Comments: | The "epidote" and "zoisite" reported by Gurlt, Hobbs, Shannon, Schairer and Sullivan in the amphibolite is actually clinozoisite. It is abundant in the altered amphibolite and at the quartz-rich contact with the marble associated with the scheelite and ferberite. Non-terminated acicular crystals typically found in small vugs where calcite dissolved out. Shannon's (1921b) wet chemical analyses and RI values fall into the clinozoisite range, even though he called the mineral epidote. Otherwsie he described them thus: "columnar ash gray to brownish gray or nearly white mineral in prismatic crystals imbedded in glassy quartz. There is a small amount of green hornblende in the quartz and patches of calcite occur as the last deposit in cavities. By dissolving out the calcite, clear brown to gray crystals of the prismatic mineral are obtained." (Shannon, 1921b). |
