|Location and accuracy||This occurrence is at sea level, at the west end of the town of Metlakatla. The site is in section 9, T. 78 S., R. 92 E., of the Copper River Meridian. It corresponds to loc. 24 in Berg (1972 [I 684]), loc. 148 in Elliott and others (1978), and loc. 47 in Karl (1992). The location is accurate within 0.1 mile.|
Geologic descriptionThe country rocks in the area of this site are schist, hornfels, and gneiss derived from an assemblage of undivided volcanic, sedimentary, and intrusive rocks of Silurian and Ordovician age (Berg, 1972; Berg and others, 1988). The rocks are polymetamorphic: the latest metamorphism, to greenschist grade, probably occurred in Late Cretaceous time. The occurrence consists of sparsely disseminated pyrite, chalcopyrite, and traces of malachite in schist (Berg, 1972, loc. 24).
