Geologic setting

Geologic description

This occurrence is a brecciated, iron- stained sandstone of the Upper Cretaceous, Kuskokwim Group that contains quartz veins (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). Samples of the iron-stained breccia zones with quartz veins contained 70 parts per million (ppm) antimony, 850 parts per billion (ppb) mercury, and 50 ppm arsenic (McGimsey and others, 1988).
