Abstract
The Coastal Plain sediments of Fayette and Lamar Counties, Ala., are pre-Selma Late Cretaceous in age and are divided into three mappable units, from oldest
to youngest: (i) the Coker formation, (2) the Gordo formation, and (3) a unit composed of the McShan and Eutaw formations undifferentiated. The Coker formation as here defined includes the Cottondale, Eoline, and Coker formations of earlier workers; the name Gordo is used as previously defined. The Coker and Gordo formations constitute the Tuscaloosa group. Structure contours on formational contacts locally show marked irregularities that are partly the result of structural disturbances. Some of these disturbances were probably of post-Morreville (post-Austin) age.
