dc.description.abstractThe stratigraphic nature, palynological constituents, and petroleum potential of the Kanguk Formation and contiguous strata have been assessed by combining palynology, sedimentology, and Rock-Eval/TOC pyrolysis. In the northeastern Sverdrup Basin the Kanguk is ?latest Cenomanian/early Turonian to Campanian in age. It constitutes a depositional sequence bounded by two major unconformities throughout the study area except at Remus Creek. The lower unconformity spans the Albian-?latest Cenomanian/Turonian interval whereas the upper unconformity includes the late Campanian-Paleocene interval. Both unconformities are diachronous. In the northeastern Sverdrup Basin the Kanguk Formation can be traced from coastal areas (Mount Bridgman) westward to offshore areas (Glacier Fiord). Marine and terrestrial palynomorphs are well-preserved and represented by 428 taxa, including 226 marine and 202 terrestrial species. One new marine dinocyst genus (Ibaidinium g. nov.), seven new marine dinocyst species (Chatangiella kangukensis sp. nov., Ibaidinium canadensis sp. nov., Ibaidinium inuitei sp. nov., Ibaidinium mertxei sp. nov., Luehndea brevispinosa sp. nov., Odontochitina octopusa sp. nov., and Trithyrodinium verrucosum sp. nov.) and a new terrestrial pollen species (Wodehouseia arctica sp. nov.) have been recognized. The genus Ibaidinium g. nov. and the species Odontochitina octopusa sp. nov. are age-significant and restricted to the latest Coniacian. Based on the palynological content, the Kanguk Formation can be subdivided into a lower marine dominated interval and an upper terrestrial dominated interval. The formation has been subdivided into four biozones. The upper three biozones roughly correlate with previously established hiozones for the Kanguk Formation or equivalent units. A combination of sedimentological and Rock-Eva1iTOC pyrolysis data supports the presence of three informal members in the Kanguk Formation, namely the "Mount Bridgman member", the " bituminous member", and the " Remus Creek member". The "Mount Bridgman member" and the " bituminous member" are, in part, laterally equivalent and represent coastal and offshore deposition respectively. The "bituminous member" was deposited in anoxic, offshore environments, and is correlative to the worldwide Cenomanian/Turonian anoxic event. It may represent a good source-rock for oil and gas, whereas only gas could be generated from the deltaic " Remus Creek member"and the coastal "Mount Bridgman member". The nature of the Kanguk Formation and the marked variations in thickness might be indicative of deposition in a tectonically active basin as suggested also by the abundance of bentonite beds. This tectonic activity would be linked with the Eurekan Orogeny.en
