• Occurrence and distribution of barite in the permo-triassic siksikpuk formation along the Brooks Range haul road

      Barite commonly occurs in Permian to Triassic age rocks along the north flank of the Brooks Range. The Siksikpuk Formation (Wolfcampian to lowest Guadalupian age) is noted for its barite and is well exposed in the vicinity of Galbraith Lake along the pipeline haul road (Figure 1). The proximity of these barite deposits to an existing road made them a logical selection for investigation. The study was designed to provide detailed stratigraphic information on barite quantity and quality, associated clay mineralogy, and relationship of barite to environments of deposition.
