Location and accuracy The Wiehl Mountain occurrence is low on the west flank of Wiehl Mountain approximately 3 1/4 miles southeast of the confluence of the Bettles and Middle Fork Koyukuk rivers (NE1/4 sec. 7, T. 32 N., R. 9 W., of the Fairbanks Meridian). The location was approximated from a 1:250,000-scale drawing in Dillon (1982) and is accurate within a 1-mile radius.

Geologic setting

Geologic description

This occurrence is described as a vein containing fine-grained pyrite, hematite, and possibly a little stibnite in a carbonate gangue (Dillon, 1982). No other descriptive information is available for this occurrence. The country rocks near the occurrence are Devonian to Silurian(?) marble overlying and in fault contact with Ordovician black phyllite and marble and Ordovician to Cambrian(?) marble (Dillon and Reifenstuhl, 1995). The host for the mineralization was not specified.
