Geologic setting

Geologic description

A quartz vein in granodiorite can be traced for about 200 feet along the shoreline (Maas and others, 1991, 1995). The vein contains chalcopyrite, marcasite, pyrite, and pyrrhotite. A 0.5 foot sample contained 1,294 parts per billion gold and 11.23 ounces of silver per ton (Maas and others, 1991, 1995). The vein is at or near the contact between a Cretaceous granitic pluton and Silurian Heceta Limestone (Eberlein and others, 1983; Brew, 1996).

Mineral deposit model Polymetallic vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c
Age of mineralization Probably related to the emplacement of the Cretaceous granitic host rock.
