Comments on the geologic information

  • Geologic Description = Scheelite occurs within a discontinuous idocrase-garnet skarn in interlayered calc-silicate schist and impure marble along a contact with a lower Tertiary granite pluton (Nokleberg and others, 1987, p. 34). The schist and marble are part of the middle Paleozoic or older Yukon-Tanana terrane (Nokleberg and others, 1987, p. 34).
