Comments on the geologic information

  • Geologic Description = A poorly exposed outcrop of Tertiary sedimentary rocks occurs at this locality. The outcrop consists of alternating 4-inch-thick beds of lignitic coal and black mudstone. The bedding strikes N. 50 E. and dips 40 SE. A sample of carbonaceous sandstone contained 213 ppm U3O8 and 26 ppm Th (Barker, 1985).
  • Age = Tertiary.
