N2 - Sedimentary facies analysis of the Upper Permian Bredehorn Member, Schuchert Dal Formation shows that it is composed of eight sand-rich facies that can be classified as Bouma sequences. The turbidites are grouped into six facies associations that form different parts of two lowstand fan systems in northern Jameson Land. The larger, Biskop Alf Gletscher-Oksedal fan extends for more than 30 km north-south. In the southern proximal part it is composed of channels and proximal lobe deposits with a composite thickness of 127 m. In the northern, more distal outcrops it consists of outer lobe deposits. Outcrops of the smaller, marginal Store Blydal fan are composed primarily of lobe sediments. Transport directions in both fans indicate north- and northeastward flow of the turbidites reflecting redistribution by axial turbidity currents of the transverse westerly infill. The northward tilting of the basin conforms with the data from the underlying Carboniferous fluvial systems but contrasts to the southward tilting of the Jurassic basin. Both fans are composed of three turbidite systems that can be correlated laterally. They are separated by shales. Each system represents deposition during sea-level lowstand, and the Bredehorn Member represents three events of lowstand fan deposition. The oldest part of the fan systems was deposited during latest Ravnefjeld Formation times and the sandstones are encased in organic-rich, source-prone shales.
