Basin 4 of the Brazos-Trinity Lowstand Systems Tract - Ultra-High Resolution 3-D Investigation of a Pleistocene Intra-Slope Basin, W. Gulf of Mexico

A028 BASIN 4 OF THE BRAZOS-TRINITY SLOPE SYSTEM Introduction 1 We have executed an ultra-high resolution 3-D investigation of the stratigraphy and basin fill history of a 200 km 2 Pleistocene intra-slope basin in the western Gulf of Mexico. This basin represents the southernmost portion of the Brazos-Trinity Slope System; a system of four basins linked by submarine channels (Basin 4; Winker 1998; Beaubouef and Friedman 2000; Badalini et al. 2000; Beaubouef et al. 2003a b c and references therein). This system is located down-dip of the ancestral Brazos and Trinity rivers and their associated deltas (Fig. 1a). These shelf
