摘要：

Forty seven vibracores and fifteen radiocarbon dates have been obtained to outline the Holocene history of the North Inlet salt marsh basin. Marsh deposits date from about 3500 years BP and have transgressed over a Late Pleistocene beach-ridge terrain that was partly eroded by Late Holocene tidal channel meandering. Marsh mud also has prograded southward over shallow subtidal estuarine Macoma muds which date from about 4500 years BP and which are still accumulating in adjacent Winyah Bay. The southward migration of the marsh environment probably is due to the southward migration of both North Inlet and the mouth of Winyah Bay. The stratigraphy of the North Inlet basin offers no evidence for Late Holocene sea-level oscillations. Application of this model of marsh history to the study long-term ecosystem succession driven by slowly rising sea level is discussed.
