Abstract

The assumption of absolute tectonic stability during Pleistocene time has influenced most previous attempts to map, name, and correlate relict shorelines and surficial deposits on the southern Atlantic coastal plain. This study is the first to correlate shorelines throughout the region independently of that assumption. Topographic shoreline features were mapped and differentiated into age groups on the bases of progradational discontinuities, contrasts in the state of preservation, and changes in coastal morphology. Three shoreline sequences are well preserved, permitting paleogeographic reconstructions. A combination of published and direct geomorphic evidence suggests that all three shoreline sequences have been deformed. Warping continued through Pleistocene time, following persistent Cenozoic structural features.
