Late Cenozoic Evolution Of Sedimentation And Slope Stability Along The U.S. Atlantic Margin, Bradley Kevin Craig

Electronic Theses and Dissertations

The U.S. Mid-Atlantic margin,from the Norfolk Canyon south to Cape Hatteras, exhibits three major seafloor morphologies: elongated shelf-edge blowouts, the Currituck submarine landslide, and a large slope-sourced canyon failure. The late Cenozoic evolution of slope stability on the Middle Atlantic margin can be linked to the framework geology as well as spatial and temporal variations in sedimentation patterns across the margin. The framework geology impacts sediment pathways, while the shape of the margin influences the position of sediment depocenters across the margin. Changes in sedimentation rates and sediment source dictate the amount of sediment being delivered to each region and …
