Problems with plate tectonic models for Baffin Bay Nares Strait: evidence from the Labrador Sea

Plate tectonic models for the geologic development of Baffin Bay require major strike-slip displacement through Nares Strait. However, these models are based mainly upon observations made in other areas, such as the Labrador Sea, the North Atlantic, or the Arctic Ocean. This paper reviews a synthesi...
