A Guide to the Geology of Delaware's Coastal Environments
註釋The low-lying Delaware coast includes the highly varied geomorphic elements of a major estuary; highlands undergoing erosion; spits; dunes, marshes; and a lagoon-barrier shoreline. Vertical sediment sequences and geomorphic patterns as interpreted in this study should form useful models in deciphering paleogeography an sedimentary processes of coastal change. The three major elements of coastal change identified include: (1) the relative rise in sea level (now proceeding at a rate of approximately 1/2 foot per century), (2) coastal erosion and deposition processes, and (3) the resultant sequences of sedimentary lithosomes which reveal the past history of coastal change. The physical elements of the coastal geology are illustrated with photographs comparing details on the surface and from the air. Many diagrams and cross sections interpret and project and structural information obtained in field surveys. (Author).
