Reprocessed COCORP southern Appalachian reflection data: Root zone to Coastal Plain

Abstract

COCORP (Consortium for Continental Reflection Profiling) seismic reflection data from the Atlantic Coastal Plain and eastern Piedmont in Georgia have been reprocessed and interpreted. Dipping events correlated with the master decollement root zone may be the only features that can be correlated with other reflection lines. Farther southeast on the Coastal Plain the shallow section is improved to produce reflections corresponding to the base of the Coastal Plain. A Triassic basin is confirmed to be more than 2 km deep and is the only major basin accurately revealed by the seismic lines. Improvement of the shallow seismic data is important to understanding the deep data. Some apparently deep reflections are probably produced from within the shallow Coastal Plain. Even though these shallow data have been improved, the Augusta fault is not interpreted as a major reflective feature.
