Excerpt: ...with interbedded sands and more rarely sandstones, lying unconformably above the Hattiesburg clay, has been called the Pascagoula clay. This formation is locally fossiliferous and has furnished remains of marine or brackish-water invertebrates at Shell Bluff and Givhens Landing, on Chickasawhay River, Miss., and in numerous wells in the southern part of the State. A somewhat different fauna has been obtained from the formation at Pine Prairie and southwest of Alexandria, . La., and at Burkeville, Tex. The formation ranges in thickness from about 250 feet in Alabama to 450 feet near Mississippi River in Louisiana and along the Gulf coast in Mississippi. In western Louisiana and eastern Texas the thickness has not been accurately determined but it is thought to be about 250 Local Variations in thickness are to be expected, because the Pascagoula clay is overlain unconformably by sands and clays of Pliocene age and rests unconformably on the Hattiesburg clay. The Pascagoula clay differs from Johnson's Pascagoula phase or formation2 by including the portion of his Fort Adams or Ellisville phase extending from Tunica, La., to Columbia, Miss. The type locality is, however, the same, and the difference is largely due to a more thorough understanding of the distribution of the formation. West of Mississippi River the Pascagoula clay extends across southern Louisiana and eastern Texas and includes the upper portion of what Veatch' called the Fleming clay. CITRONELLE FORMATION. The Pascagoula and Hattiesburg clays and the Catahoula sandstone are in places overlain by sands, gravels, and clays that from their fossil flora (identified by E. W. Berry) are known to be of Pliocene age. These deposits, which heretofore have been called...
