|Location and accuracy||This occurrence is at an elevation of 3,200 feet on the northeast flank of Paxson Mountain, 1 mile west of the south end of Mud Lake. It is on an east-flowing creek at the SE1/4SW1/4 section 1, T. 22 S., R. 11 E., Fairbanks Meridian. The occurrence corresponds to locality 2 in Rose and Saunders (1965) and to locality S94 in table 2 of Nokleberg and others (1991).|
Geologic descriptionThis occurrence consists of a quartz-epidote vein, 3 inches thick, that contains bornite partly oxidized to chrysocolla (Rose and Saunders, 1965). The vein is in altered and sheared pillow metabasalt of the Nikolai Greenstone of Late Triassic age (Nokleberg and others, 1991). The metabasalt locally is altered to epidote and chlorite and is cut by a dark aphanitic dike.
