Abstract

In the inner to middle Sable Subbasin, offshore Nova Scotia, a thick (~100-200 m) and areally-extensive (>20 km x > 100 km) sheet-like fluvial-marine succession has been identified at the top of the Missis-auga Formation using core, well log, and seismic (2D and 3D) data. Despite its relatively planar nature and significant width perpendicular to interpreted paleoflow (at least 20 km), the base of the fluvial sheet is interpreted to be a wide incised valley formed during slow relative sea level fall and lowstand. Deposition of the fluvial-marine succession has occurred during subsequent slow relative sea level rise, which was punctuated by several higher frequency relative sea level falls that episodically caused fluvial systems to bypass the shelf, allowing for continued shelf margin progradation.
