AbstractSedimentary basins within the Labrador-Baffin Seaway are the product of rifting between Greenland and the paleo-North American Plate. Rifting started in the Early Cretaceous, with seafloor spreading initiated in the Paleocene and ending near the Eocene-Oligocene boundary. A change in the spreading direction in the latest Paleocene resulted in transform offsets in the Davis Strait and along fracture zones in Baffin Bay, with deformation in northern Baffin Bay during the Eurekan Orogeny. Since the stratigraphy of western Baffin Bay is poorly constrained, analogues are used from the well studied Labrador and West Greenland margins and exposures on nearby Bylot Island. The generally northwest-trending basement structures are infilled with Cretaceous strata, which are overlain by a seaward-thickening wedge of post-rift Paleocene to Middle Miocene sedimentary rocks. Finally, a thick Middle Miocene and younger interval blankets the deep water and oceanic crust, with clinoforms locally developed on the shelf.
Summary(Plain Language Summary, not published)
This paper presents a detailed summary of previous work on the Baffin Island margin in regards to the stratigraphy. We further present new information by integrating recent studies with seismic mapping.
