Wrangellia geologic mapping

Project Details

  • Status:

    Active
  • Nickname/Abbreviation:

    Wrangellia
  • Description:

    Strategic and critical minerals assessment in the western Wrangellia terrane, south-central Alaska; a multi-year project to understand and improve the geologic framework of the Wrangellia geologic belt, with particular emphasis on evaluating the potential of the area to host magmatic-type nickel, copper, and platinum-group-element (Ni-Cu-PGE) deposits. Includes detailed geologic mapping in the Talkeetna Mountains Quadrangle, 2014 STATEMAP grant no. G14AC00167
  • Project Date(s):

    2014 - 2017
