Extensive Cretaceous-Paleogene sedimentary basins are known along the western side of Baffin Bay from southern Davis Strait to southern Nares Strait and it is hypothesized that the region may contain significant hydrocarbon deposits, particularly within the vast basin at the mouth of Lancaster Sound (Harrison et al., 2011) and along the continental shelf of eastern Baffin Island Moir et al. (2012). A persistent oil seep offshore of Scott Inlet, Baffin Island, demonstrates that petroleum systems are present in the region. Limited geological data exist for the offshore region in this area, with only a few shallow drill holes and dredge samples, and an ODP well near the Baffin Shelf. Understanding the correlative onshore sequences can serve as a ready analogue for the offshore deposits. Such onshore sequences are limited to only a few localities, however, including Bylot Island and adjacent areas of northern Baffin Island (Fig. 1).
Limited geological and paleontological surveys of the onshore strata were undertaken by industry and university personnel in the 1970s-1980s, and a preliminary, mostly unpublished, litho- and biostratigraphic framework was established at that time. Reconnaissance fieldwork undertaken under the GEM-1 program determined that the basic elements of a petroleum system are present in the Bylot Island region (Brent et al., 2013), but subsequent field studies necessary to fully describe the succession and to provide detailed insights into the geology of the offshore region were postponed. Undertaking these activities under GEM-2 will finally provide an extended data set valuable for better understanding depositional systems of Baffin Bay.
Summary(Plain Language Summary, not published)
The authors present a summary of their 2018 research activities studying sedimentary rocks preserved in onshore areas of Bylot Island and adjacent Baffin Island, northeast Nunavut, under the GEM2 geoscience research program. These rocks have equivalents in the offshore region of the Baffin Island continental shelf and understanding the nature of the sedimentary rocks preserved in onshore areas helps in interpreting the rocks preserved in the offshore areas.
