Geologic setting

Geologic description

This prospect is in amphibole-mica schist, and consists of a vertical layer, 18 inches thick of tremolite asbestos that strikes N 45 W and can be traced on the surface for 60 feet (Race and Rose, 1967; Wells and others, 1986). The deposit contains veins of cross-fiber asbestos 0.75 inch thick and 6 to 8 inches long (Cobb, 1978 [OFR 78-374]). Prior to 1930, the Alaska Asbestos Company, Inc. dug an opencut across the belt of tremolite schist, and constructed a road from the beach to the property (Roehm, 1943).
The rocks in the general area are mainly Ordovician and Devonian to Triassic clastic units, mafic-intermediate volcanic rocks, and subordinate limestone. The bedded rocks are intruded and locally metamorphosed by Cretaceous granodiorite (Gehrels and Berg, 1994).
