Magmatic and Structural Framework of PGE and Other Mineralization in Northwestern Wrangellia, Central Alaska

Résumé du livre

This report summarizes the findings of a multiyear Alaska Division of Geological & Geophysical Surveys (DGGS) project to better understand the geologic context of mineralization hosted by the Wrangellia terrane in the eastern Alaska Range and Talkeetna Mountains, with particular emphasis on evaluating the area’s potential for hosting the strategic and critical platinum-group elements (PGEs) and cobalt (Co). Subeconomic concentrations of these elements are already known to occur together with nickel (Ni) and copper (Cu) in magmatic-sulfide-type deposits. We take a mineral systems approach, our goal being to understand the ore-forming processes in order to assess the potential for undiscovered, economically extractable mineralization to occur in the study area.
