Capsule Geology

The Sku showing area is underlain by rocks of the Weaver Lake Member of the Lower-Middle Jurassic Harrison Lake Formation, comprised of a varied assemblage of basaltic to rhyolitic flows, tuffs and breccias. These flows and pyroclastics are intruded by a small quartz diorite stock described as Late Jurassic in age (Arthur, 1987). The Harrison Lake rocks are altered near the contact. Alteration is comprised of intense silicification and pyritization. Pyrite with minor chalcopyrite occur as disseminations or as fracture fillings in the contact rocks.
