Crustal Structure Of The Continental Margin Of The Eastern United States

Abstract

Gravity data from the Cape May region of the eastern United States was employed to determine the behavior of the crust-mantle interface in the transition region of the continental margin. By using the Talwani method of approximating two-dimensional structures with polygons, it was determined that the depth to the Mohovoricic discontinuity may decrease linearly from 25 kilometers depth 160 kilometers landward of the shelf break to 10 kilometers depth at the shelf break, More realistic results using this approach would require better data control in the shelf break region and near shore continent.
