Abstract: Regional Cretaceous Cross Sections--South Texas
D. G. Bebout, R. A. Schatzinger (2)
Regional studies at the Bureau of Economic Geology of facies distribution and depositional environments of Lower Cretaceous carbonate strata have emphasized the need for a network of regional cross sections. The following sections were constructed to meet this need and are meant only to show the general changes in lithology and thickness within and between formations. In order to show these changes more clearly, faults have been omitted from the sections. Similar cross sections which extend farther downdip and include primarily Tertiary formations have been published by the Bureau of Economic Geology (Bebout, and others, 1976).
Formation tops have been taken from many sources. The Tertiary tops are mainly from unpublished cross sections constructed for the Bureau of Economic Geology's geothermal project and from the tertiary cross sections cited above. The tops of Cretaceous units have been picked with the aid of published reports by Tucker (1962), Winter (1961), and Flawn (1961). Also consulted were unpublished cross sections provided by Exxon Company U.S.A., Tenneco Oil Company, and additional Bureau of Economic Geology sections.
