Upper Triassic to Lower Jurassic stratigraphy along the northeastern margin of the Sverdrup Basin, Axel Heiberg and Ellesmere islands, Nunavut : new data from measured sections / D. Midwinter, T. Hadlari,... : M183-2/8855E-PDF

"Two stratigraphic sections were measured through Late Triassic - Early Jurassic aged strata in the Blue Mountains map area (NTS 340-B/11) on Ellesmere Island and the Depot Point map area (NTS 049-G/7) on Axel Heiberg Island. These sections are subdivided in terms of established member and formation names based on previous mapping along the north-eastern margin of the Sverdrup Basin. The lowermost strata in the Heiberg Formation, the Romulus Member (510-575 m thick), is a coarsening-upward succession of mudstone to fine-grained sandstone from a prodelta to delta plain environment. The overlying Fosheim Member (317-425 m) is a coal-bearing and sandstone-rich interval from a mixed alluvial-marine environment, such as a delta plain. It is overlain by the Remus Member (100-112 m); a sandstone-rich unit representative of shallow marine deposits. The Heiberg Formation at Depot Point is of similar thickness (1009 m) to the Blue Mountains (1035 m) and may represent a marginally more distal basinal setting with a thinner Fosheim Member but a slightly thicker Romulus and Remus members"--Abstract, page 1.
