Figure 27-Reconstruction (in sequence [animation]) of the southern Texas fault system above autochthonous salt (black). This end-member model assumes large extension during Wilcox deposition, but a continuum of models, trading the width of Upper Cretaceous salt walls for Tertiary extension, is geometrically possible. LK = Lower Cretaceous, UK = Upper Cretaceous, Uwx = Upper Eocene Wilcox. Sea water is stippled. Reconstruction is by the MESH method.
