| Location and accuracy | Cobb (1972, MF-413), loc. 18, 19; NE1/4 sec. 8, T. 2 N., R. 1 E., of the Fairbanks Meridian. This prospect is on the ridge between Seattle Creek and Moose Creek No. 2, about 2.5 miles southwest of the summit of Pedro Dome. |
Geologic descriptionA 3-foot zone of scheelite was found in weathered schist; most was disseminated, but there were a few high-grade spots. The scheelite zone strikes N 44 E and dips 45 SE. The average tungsten tri-oxide content was estimated at 0.5 to 1% (Joesting, 1943). Byers (1957) reported that channel samples across 4.5 feet of the disseminated scheelite zone contained 0.48% tungsten tri-oxide. A fine-grained quartz diorite dike was found 8 feet below the surface in the bottom of a small pit sunk in the same trench where the scheelite was encountered (Joesting, 1943). Bedrock is quartz-mica schist and quartzite (Byers, 1957). | |
