Geologic setting

Geologic description

At this occurrence, pyrite forms disseminations and coats fractures in Permian (?) metadacite intrusive rocks and in fragmental volcanic rocks of the Slana Spur Formation of Pennsylvanian age (Hanson, 1963). This occurrence is one of the four prominent areas of pyrite and chalcopyrite disseminated in dacitic tuff noted by Hanson (1963, p. 67, figure 5).
