Geologic setting

Geologic description

This occurrence is a zone of intense iron-oxide alteration in sandstone of the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). As exposed in rubble, veins of secondary hematite of uncertain extent and orientation crosscut the sandstone beds. Grab samples of the hematite-rich veins contain up to 150 parts per million arsenic, and trace amounts of antimony, mercury, silver, and gold (McGimsey and others, 1988).
