Tectonic geomorphology of the southeastern Mississippi Embayment in northern Mississippi, USA

摘要

We analyzed drainage-basin geometry in part of the southeastern Mississippi Embayment near the New Madrid seismic zone in order to detect areas of lateral stream migration that could indicate recent tectonism. Toward this goal, a field of drainage-basin asymmetry vectors was generated from a digital terrain model and compared to geologic structure, lithofacies, seismicity, remotely sensed lineaments, and major drainage divides.
