Geologic setting

Geologic description

The Muck Creek area is underlain by Upper Cretaceous granitic rocks that may contain uranium-bearing minerals (Gault and others, 1953). Two pan-concentrate samples of stream gravels contained 0.125 percent and 0.16 percent equivalent uranium. Heavy minerals from the concentrate include garnet, hornblende, augite, sphene, zircon, epidote, apatite, scheelite, powellite, ilmenite, hematite, limonite, magnetite, uranothorianite, and pyrite.
