Abstract(Summary)
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 and along the continental shelf of eastern Baffin Island. A persistent oil seep offshore of Scott Inlet, Baffin Island, demonstrates that petroleum systems are present in the region. Only 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 Baffin Island.
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the onshore strata were undertaken by industry and university personnel in the 1970s-1980s, and a preliminary, mostly unpublished, litho- and biostratigraphic framework was established at that time.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, 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 have studied sedimentary rocks that formed during the Cretaceous-Paleogene period of geologic time, approximately 110 to 60 million years ago, and that are found today on Bylot Island and on adjacent areas of Baffin Island, northeast Nunavut. The objective of the authors' study has been to better constrain the succession of rock types found in this region, in particular to more precisely understand the ages of the rocks and the environments that they formed in, such as ancient river systems, or on the sea bottom. The authors will use this information to develop models of the changing geography of northeast Nunavut during the Cretaceous and Paleogene ages. This information is also useful in helping to formulate programs for assessment of the hydrocarbon potential of offshore regions of Nunavut, such as the Baffin Shelf.
