5203 |a"During the Early Cretaceous, rifting began between the paleo-North American and Greenland plates, eventually resulting in the development of the Labrador Sea, Davis Strait, and Baffin Bay regions. Along the western side of the Labrador Sea, the Labrador margin includes the Hopedale Basin and southern portion of the Saglek Basin. The Saglek Basin continues northwards into western Davis Strait, extending along the southeast Baffin Shelf. These depocentres record sedimentation from the Early Cretaceous syn-rift phase, late rift phase in the Late Cretaceous, drift phase or period of seafloor spreading in the latest Cretaceous to earliest Oligocene, and in the post-drift phase from the earliest Oligocene to Pleistocene. A total of 28 wells intersect the Mesozoic–Cenozoic section in these basins and document an important stratigraphic record for the region. Studies of these wells have included lithostratigraphic, biostratigraphic, and paleoenvironmental analyses, some with a regional or semi-regional undertaking. However, more recent studies have provided new understandings of the age and distribution of the eight formations that make up the stratigraphic succession along the margin. The present study focuses on incorporating existing well data to develop comprehensive and consistent paleoenvironmental interpretations for the wells of the Labrador margin and southeast Baffin Shelf. Lithological, well log, fossil content, and core descriptions are presented and interpreted to produce a regional understanding of paleoenvironmental change through time. In addition, lithostratigraphic boundaries and respective type and reference sections are modified to better fit lithological changes, well-log breaks, biostratigraphic hiatuses, and/or abrupt paleoenvironment changes. This revised paleoenvironmental and lithostratigraphic framework will help to serve future basin history studies in the region"--Abstract, page 1.
