Geologic descriptionThis occurrence consists of a pyrite-rich dolomitic vein that cuts sheared volcaniclastic rocks of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). Samples of the vein and of nearby rhyolite were reported to be marginally anomalous in copper, lead, arsenic, and antimony (Wilson and others, 1988). | |
