Preliminary characterization of two coals from the upper Prince Creek Formation, Sagwon Bluffs, North Slope, Alaska

In July of 2018, the Alaska Division of Geological & Geophysical Surveys (DGGS) studied and sampled the coal beds within the upper section of the Prince Creek Formation at Sagwon Bluffs. Sagwon Bluffs lies 55 miles south of Deadhorse (Prudhoe Bay), Alaska, and approximately one mile east of the Dalton Highway, on the west side of the Sagavanirktok River. At Sagwon Bluffs, Upper Cretaceous to Paleocene rocks of the Prince Creek and Sagavanirktok Formations are exposed. The upper Prince Creek Formation at this location contains several distinct coal seams interbedded with fine-grained fluvial sandstone. A lower coal seam and an upper seam were channel sampled for this study. This Preliminary Interpretive Report presents results from coal quality (proximate and ultimate analysis), Rock-Eval, vitrinite reflectance, and kerogen microscopy analyses. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30556.
