The sequence of profiles showTi in this figure ilkistrates the transition from the typical continental shelf, continental slope, continental rise profiles of the north- eastern United States to the more complex profiles across the Blake Plateau and marginal basin of the southeastern United States.

Note the well-developed marginal escarpment and outer ridge on the lower three profiles. (After Heezen et al., 1959.) 1959). It can be safely predicted that if tectonic activity in the area diminishes, sedimentation will eventually completely fill the offshore basins of the con- tinental borderland one by one and produce a shelf-like feature which may eventually resemble a marginal plateau very similar to the Blake Plateau. The analogy seems rather good M^hen one compares the deeper structure revealed by results of seismic-refraction A\oi-k on the Blake Plateau with the modern to])o-
