Abstract:Understanding the Mesoproterozoic and younger structural history of the Eclipse Sound/Pond Inlet area is essential for the interpretation of its Archean to Paleoproterozoic geological history and could have important implications for mineral and petroleum exploration models in the northern Baffin Bay area. The identification of potentially active faults is critical for understanding possible earthquake-related hazards in the area. The integrated interpretation of 1970s-vintage marine seismic data with hill-sha… Show more
The Northeast Canada Rifted Margin (NCRM) Composite Tectono-Sedimentary Element (CTSE) developed during a long and complex history that produced two tectono-sedimentary elements (TSEs): (1) the pre-rift TSE of pre-Cretaceous age; and (2) the syn-rift TSE of Early Cretaceous-Paleocene age. The pre-rift TSE includes the oldest and most poorly known offshore sedimentary accumulations which mainly evolved in a cratonic setting. In contrast, Cretaceous-lower Paleocene sedimentary basins of the syn-rift TSE are known from several wells, seismic data, outcrops, and seabed samples, and their extent and distribution are mapped in most parts of the margin. The syn-rift TSE is the most prospective part of the margin and hydrocarbon shows have been documented in some wells and offshore seeps studies. This review provides insights into the Paleozoic-Cenozoic evolution of the NE Canada rifted margin in the Labrador Sea, Davis Strait, and Baffin Bay. In this context, we discuss structural inheritance and rift development, and account for confirmed and potential hydrocarbon systems and plays.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
