    In this study existing wide-angle seismic transects from the central Atlantic passive continental margins are revisited, and regions of exhumed upper mantle, seaward dipping reflectors (SDRs), and thin oceanic crust are identified and mapped.

Because the continental margins surrounding the Atlantic Ocean and primarily passive, weathered pieces of land erode from the nearby continent to make a thick band of undisturbed sediments.

This synthesis covers stratigraphy, depositional processes, and geophysical interpretation of the major onshore and offshore marginal basins from Maine to the Bahamas, and includes an up-to-date review of thinking on regional tectonic history.

U.S. Atlantic continental margin: a typical Atlantic-type or passive continental margin -- Marine physiography of the U.S. Atlantic margin -- U.S. Atlantic continental margin: structural and tectonic framework -- History of studies of the Atlantic margin of the United States.

Stratigraphy, depositional processes, and depositional history. The U.S. Atlantic continental margin (Plate 2C, Fig.

1) is one of the best studied passive (Atlantic-type) continental mar- gins. As the U.S. margin evolved through compressional, exten- sional (rifting), and vertical (subsidence) tectonic phases, a distinctive set of deep crustal structures, basement stractures, and sedimentary features was created.

To the west, a short continental slope rises to a continental shelf. This Blake Plateau morphology characterizes the margin east of Florida and north of the Bahamas. North of Florida the margin merges into the typical shelf-slope-rise morphology.

The eastern North American passive margin includes the Atlantic continental margin from the Bahamas to Baffin Bay. Formed by the rifting, breakup, and drift of North America away from Africa and Europe, the margin′s thick sedimentary cover of Mesozoic to Cenozoic age lying over the Coastal Plain, continental shelf, slope, and rise straddles three distinct basement types:.

Atlantic-type continental margins have been studied most extensively in the North Atlantic, but a significant assemblage of data provides insight into the structure of the continental margin of west Africa, Argentina, and by: Baltimore Canyon Trough is the deepest depocenter for Mesozoic and Cenozoic sedimentary rocks along the U.S.

This subject was chosen for two reasons. One of the few attempts to date to map gas hydrate over a large area has been made on the Atlantic continental margin of the United States (Dillon et al., ). This work has resulted in the production of an extensive data base of seismic reflection lines including both single and multichannel lines, and complete GLORIA sidescan sonar coverage.

Regional tectonism on the Atlantic coastal margin is expressed in a variety of ways such as uplift, subsidence, tilting of the landmass, geomorphic features, seismicity, and faulting.

Of these features, faulting probably is the most definitive evidence of crustal deformation. This chapter summarizes the major findings of the foregoing chapters and highlights the critical factors in the geologic development of the U.S.

Continental margins on the trailing side of tectonic plates, like those around the Atlantic Ocean, are broad, with gentle continental slopes and well-developed continental rises. The adjacent land area is commonly a broad coastal plain that.

Continental margins have been the subject of increasing attention in recent years, an interest focused by a body of new data that has provided new insights into. A passive continental margin occurs where the transition from land to sea is not associated with a plate boundary.

The east coast of the United States is a good example; the plate boundary is located along the mid Atlantic ridge, far from the coast.

Instead of ending in a continental rise, the continental slope of this type of margin often plunges into a deep-ocean trench, which may be filled with sediment.
