The tectonic setting and depositional environments along the ancient margin during the Mesozoic of the East Coast of the United States may have been similar to those in the present Gulf of Elat (Aqaba). The Gulf of Elat (Aqaba) is the northern continuation of the Red Sea rift zone, where carbonates are accumulating contemporaneously with clastics under arid conditions. Clastics are deposited primarily in alluvial-fan complexes which spill out onto a narrow shelf. Carbonate deposits, including reef complexes, occur along the shelf break. In comparison, along the United States East Coast margin, Triassic to Early Jurassic rifting coincided with carbonate and clastic deposition. The Middle Jurassic and Cretaceous strata reflect the transition from synrift to postrift stages of tectonic evolution. Seismic and well data of the Jurassic and Cretaceous sections show an increase in the carbonate content approaching the United States East Coast shelf break. A discontinuous belt of carbonate buildups is inferred along the United States East Coast shelf and slope. The Gulf of Elat (Aqaba) represents an analogous model for the Early Jurassic East Coast margin of the United States. Beginning in the Middle Jurassic, the East Coast shelf-edge carbonate sequences were being deposited on a passive margin. Carbonate growth may have outpaced subsidence and may be similar stratigraphically to the Gulf of Elat (Aqaba) where carbonate deposits are prograding seaward.
