Along the shelf margin of the northern Gulf of Mexico, numerous late Quaternary deltaic systems occur where ancestral rivers encountered the shelf-slope break. These shelf-margin deltas are products of deposition during glacioeustatic fluctuations resulting from expansion and contraction of continental ice sheets. Lowered sea level shifts paralic environments seaward and creates widespread subaerial unconformities, well-defined drainage networks (incised valleys), and deltaic systems that prograded to the shelf margin. Shelf margin deltas are primary mechanisms for shelf margin and upper slope progradation, and serve as important conduits of sediment to deeper water environments.
