Comments on the geologic information

  • Geologic Description = The SOB occurrence consists of barite cobbles in an 11 by 24 meter zone on a hillside, surrounded by argillite of the Mississippian to Permian Siksikpuk Formation. The occurrence has been interpreted as a bedded barite deposit. A nearby drainage has blocks of ferricrete breccia (Cobb and others, 1981).
  • Age = Mississippian to Permian.
