Comments on the geologic information

  • Geologic Description = Small hill about 23-33 ft (7-10 m) high, 130 ft (40 m) wide, and 197 ft (60 m) long surrounded by tundra is made up of cobble and boulder size fragments of massive barite. The nearest bedrock exposure is 1640 ft (500 m) northeast and consists of low rubbly outcrops of Upper Mississippian black chert and shale in contact with Lower Cretaceous shale and wacke. Outcrops 1970 ft (600 m) southwest of deposit are Upper Mississippian volcanic rocks (K-Ar age 333 +17 m.y.) and sandy limestone of the Mississippian Utukok formation. Volcanic rocks probably were originally dacite or andesite. Utukok formation rocks mapped as part of a higher thrust sheet and unrelated to barite deposit.
  • Age = Late Mississippian
