S. W. LOWMAN (Shell Oil Co., Inc., Houston, Texas): Mr. Chairman, Members of the Society, and Guests: The remarks I have to make are based entirely on a single province of deposition. Therefore it seems to be in harmony with the broader interest of this symposium to outline briefly the regional and world-wide setting of that province. The Louisiana and Texas Gulf Coast takes on a broader significance when it is viewed as the northwestern, clastic province of the American intercontinental region of deposition (Fig. 1). The shallow-water areas of the southeastern part of the region are the site of carbonate deposition. These extend from the continental shelves of Florida and Yucatan southeastward to the island-bordering shelves of the Caribbean and eastward to the Bahama banks. These clastic and carbonate provinces have been compared by Tercier (1939) to those in the Australasian intercontinental region that extends from the Malay Peninsula southeastward through the East Indies to Australia. The clastic province of that region also lies to the northwest. It is represented by the Sunda shelf that lies between Borneo on the north, Java on the south, Sumatra on the southwest, and Malay Peninsula on the west. The carbonate province is well represented by island-bordering shelves in such island groups as the Celebes and Maluccas and the bird’s head of New Guinea, and also by the Sahoul shelf where carbonates are being deposited between New Guinea and Australia, and west to Timor. There is a third depositional type in both regions
