Comments on the geologic information

  • Geologic Description = Patton and Moll (1983) noted barite concretions in shale of the Whirlwind Creek Formation of Dutro and Patton (1982). Age of mineralization is believed to be Latest Silurian to lower Devonian, based on the age of the host Whirlwind Creek Formation (Dutro and Patton, 1982). Patton and Moll (1983) reported up to 50 ppm copper, 1,000 ppm zinc, and greater than 5,000 ppm barium from the shale samples.
  • Age = Age of the syngenetic barite mineralization is believed to be Latest Silurian to lower Devonian, based on the age of the host Whirlwind Creek Formation (Dutro and Patton, 1982).
  • Age = Host rock is Early Devonian - Late Silurian.
