|Location and accuracy||This occurrence is at an elevation of 3,600 feet on the northeast flank of Paxson Mountain, approximately one-half mile south of the Denali Highway. It is in the SE1/4NW1/4 section 35, T. 21 S., R. 11 E., Fairbanks Meridian. This occurrence corresponds to locality 6 in Rose and Saunders (1965) and to locality S92 in table 2 of Nokleberg and others (1991).|
Geologic descriptionThis occurrence consists of a 2-foot pod of chrysocolla and quartz in a highly altered vesicular basalt of the Nikolai Greenstone of Late Triassic age (Rose and Saunders, 1965). A massive non-vesicular hornblende basalt or andesite dike (?) is exposed about 3 feet above the copper-bearing pod.
