Geologic setting

Geologic description

Hummel (1962 [MF 248]) identified this locality as a tungsten occurrence. The ore mineral is assumed to be scheelite, probably with quartz, in veins that cross-cut the metasedimentary rocks. It is one of several scheelite occurrences in the Christian Creek, Rocky Mountain Creek, and Nelson Gulch area on the east side of Nome River. This occurrence is apparently in metasedimentary schist near a contact with intercalated marble (Hummel, 1962 [MF 248]).
