Geology

Host rock:Sonoma Volcanics
Host type:Andesite,Rhyolite
Structure:Enderlin (1993) concluded that the ore bodies formed along dilational segments of NE-trending conjugate Reidel shears associated with the NW-trending right-lateral Yellowjacket fault zone. The bodies are confined to the northeast side of this zone. All appear to be less than one mile in length., Maacama Fault Zone
Tectonic:Collision transform fault
Alteration processes:As interpreted from Enderlin (1993) and Crutchfield (1953): Early Phase: Propylitic; chlorite, calcite, albite, epidote Late Phase: Argillic (no mineral phases reported by authors) Silicic; quartz, chalcedony, adularia Crutchfield (1953) reported marcasite, limonite, and selenite as supergene alteration. Laizure (1929, unpublished) reported oxidized ore in the upper mine levels.
