|Location and accuracy||This occurrence is between elevations 3500 and 3600 feet on the crest and south flank of the ridge that separates Eureka and Moose Creeks. It is about 1/4 mile east of the head of No Name Creek, in the NE1/4 NE1/4 of section 17, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 500 feet. The site corresponds to an unnumbered mineral occurrence east of number 42 of Bundtzen, Smith, and Tosdal (1976), to number 143 of Hawley and Associates (1978), and number 54 of Thornsberry, McKee, and Salisbury (1984).|
Geologic descriptionThe country rocks in the area of this occurrence are mainly quartz-feldspar schist and quartzite of the upper Precambrian Birch Creek Schist (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, v. 2, occurrence 54). Outcrop is poor. The occurrence consists of a boulder of quartz-garnet-actinolite (tremolite) schist that contains abundant sphalerite and lesser amounts of galena and chalcopyrite. Soil samples collected along the NW trend of the Birch Creek country rocks are anomalous in lead, zinc, antimony, and arsenic (Hawley and Associated, 1978).
