Chapter 17: Atlantic and Gulf of Mexico continental margins

Abstract: The U.S. Atlantic and Gulf of Mexico continental margins are thickly sedimented passive margins that formed when Pangea split apart during Middle Jurassic time to create the Atlantic Ocean and Gulf of Mexico. Keys to understanding the process of continental breakup and its relation to preexisting structure are found in the structure of the crust beneath the sediment-filled basins and adjacent platforms and embayments that outline the margins. Because of the great thickness of post-rift sedimentary rock in the … Show more

“…Geological and geophysical aspects of the Central Atlantic opening and the evolution of its margins have been reviewed in many excellent papers (including Manspeizer, 1981;Sheridan, 1989;Trehu et al, 1989) and the plate tectonic aspects have been summarized in Olivet et al (1984) and Klitgord and Schouten (1986). The plate kinematic framework advanced in the latter publication, including rotation parameters and spreading rates, have been used without any revision in the present study.…”

“…Three of the five faults investigated here are considered to be an eastward extension of the TBRFZ (Figures 2 and 3). The en echelon geometry of this fault zone follows the underlying Lower Cretaceous carbonate shelf edge margin and south flank of the Wiggins Arch (Montgomery, 2000;Tréhu et al, 1989). The margin (and the fault zone) separates two regional Gulf Coast provinces.…”

“…1960;Hales et al 1968;James et al 1968). During the 1970s, the US Geological Survey conducted seismic reflection surveys along the US Atlantic continental margin (summarized in Pakiser and Mooney 1989) to determine the crustal structure and tectonic framework along the margin (Klitgord et al 1988;Trehu et al 1989;Glover and Klitgord 1995). Cook et al (1979Cook et al ( , 1981 interpret seismic reflection profiles in terms of thin-skinned tectonics in the southern Appalachian Mountains.…”
