Title: The Red Sea analog for the early Gulf of Mexico: Salt basins on oceanic crust

Conference ·

  1. Excalibur Interpretation Co., Houston, TX (United States)

New geophysical data from the Red Sea and the Gulf of Mexico support the concept that the early Gulf closely resembled the modern Red Sea. Oceanic crust like that now forming along the axis of the Red Sea basin may underlie much of the continental slope offshore Louisiana and Texas. Original depositional thicknesses greater than 4 km characterize both salt depocenters. The thickest salt overlies oceanic crust, probably for isostatic reasons. Deep crustal detachment faulting in a simple shear model with ductile flow below 15 km and narrow zones (up to 50 km) of severely extended crust on the hanging wall characterizes the early tectonic development. The landward edge of thick (> 2--4 km) salt generally follows the edge of oceanic crust, but the seaward edge is localized by depositional factors, modified by subsequent gravity spreading.
