Geologic descriptionWells and others (1986) describe this occurrence as pyrite in spongy quartz, associated with a northwest-trending fault in sheared and serpentinized ultramafic rock. The occurrence is currently (2001) under control of Kennecott Greens Creek. 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).
