Abstract
Abstract: Salt Tectonics and Pleistocene Stratigraphy
on the Continental Slope of the Northern Gulf of Mexico
By
During a sparker and core drill program conducted by Shell, salt
was cored on ten prominent structures on the continental slope. Combined
with seismic data, results of this study confirm previous views that the
Gulf Coast salt basin extends into the Sigsbee deep. Broad salt swells and
pillows are typical structures of the continental slope. The Sigsbee scarp
appears to be the surface expression of a salt wall. A zone of active
down-to-the-ocean faults follows the Texas shelf edge. They appear to be
related to the flow of salt at depth away from the advancing clastic wedge.
Upper Cretaceous through Holocene deep-water sediments were
cored on the continental slope. East of Brownsville the salt is overlain by
red beds of unknown age. Core holes at the shelf edge encountered deltaic
and shoreline deposits of the Pleistocene low-sea-level stages. Submarine
slides and turbidity currents carried sediments down the slope and
filled deep synclinal basins between the salt uplifts. End_of_Record - Last_Page 16--------
