Comments on the geologic information

  • Geologic Description = The area of this placer prospect is underlain by Upper Triassic calcareous shale and siltstone, cut by dikes, sills, and plugs of altered diabase and gabbro (Wilson and others, 1998). These rocks are intruded by LowerTertiary granite approximately 0.5 mile north of the prospect. The drainage basin contains two lode prospects (HE150 and HE151) as potential sources of placer gold.
  • Age = Quaternary.
