Abstract
Examination of 2D seismic data in South Texas has identified what is now interpreted to be a large, rafted block of Eocene, Paleocene, and Cretaceous strata, analogous to rafts identified in the Kwanza Basin of Angola. Preliminarily named the “Wilcox raft” because of its association with the Wilcox depotrough, it has been identified in the subsurface extending from Starr County on the Texas–Mexican border, northward over 200 kilometers into Live Oak County, Texas. The actual extent of rafted material may extend farther to the north and/or south. The raft’s detachment surface is interpreted to be at the base of...
