Capsule Geology

The Top showing area is underlain by rocks of the Weaver Lake Member of the Lower-Middle Jurassic Harrison Lake Formation. The lithology is varied and consists mainly of acidic to intermediate volcanic flows and pyroclastics ranging from andesitic to rhyolitic in composition.

A zone of shearing or apparent faulting occurs along Top Creek. Blebs and narrow veinlets of galena, chalcopyrite, pyrrhotite and pyrite with associated quartz and calcite gangue occur within this shear zone. Alteration associated with this shearing consists of pyritization, potassic alteration and minor chloritization.
