|Location and accuracy||This occurrence is at an elevation of about 4,300 feet on a south-facing slope on the northeast side of West Fork Rainy Creek. It is in the SW1/4SW1/4 section 1, T. 19 S., R. 9 E., Fairbanks Meridian. The site corresponds to locality 9 of Rose (1965) and locality S68 in table 2 of Nokleberg and others (1991).|
Geologic descriptionMinor copper staining occurs in tactite composed of amphibole, epidote, and calcite containing local pods of pyrite (Rose, 1965). The tactite is adjacent to a gabbro dike that is probably an apophysis of an Upper Triassic ultramafic-mafic intrusion (Nokleberg and others, 1991).
