Sequence stratigraphy, conodont biostratigraphy and sedimentology of Lower Permian strata of the Fosheim-Hamilton sub-basin, Sverdrup Basin, Ellesmere Island, Canadian Arctic

Northern margins of the Fosheim-Hamilton sub-basin, Sverdrup Basin, Arctic Canada, were likely bounded by the West McKinley Bay High, a Franklinian successor structure modified by Carboniferous normal faulting.;Early Permian oceanic cooling in the Sverdrup Basin is characterized by retreat of the warm-water chloroforam carbonate association from middle to inner shelf depositional environments by Latest Asselian time. Last vestiges of the chloroforam association are restricted to lagoon shores by the Artinskian.;The Simpson Reef Tract, a collection of 11 reef-mounds of middle to late Asselian age, are likely good outcrop analogues for age equivalent subsurface reef-mounds in the Norwegian Barents Sea.;Conodont biostratigraphic age correlations for Sverdrup Basin strata are proposed with stratotype sections in the Russian Ural Mountains, based on the identification of species of genus Streptognathodus. Conodont zones P3, P4, P5 and P6a are correlated as middle Asselian to lower Sakmarian.
