Goliad Formation. Clay, sand, sandstone, marl, caliche, and conglomerate; clay, commonly light shades of pink or green, calcareous concretions; sand and sandstone, medium- to very coarse-grained, locally well bedded, in part cross-bedded, light gray, mostly quartz, some black and red chert; marl and caliche poorly bedded to massive; conglomerate, black chert and dark siliceous granules and pebbles mostly at base. Thickness about 100 feet. Overlies Fleming Formation (Miocene); underlies Willis Formation (Pleistocene). Tertiary vertebrate and reworked Cretaceous invertebrate fossils fairly common. Age is Pliocene.
Mapped in De Witt and Lavaca Cos., southeastern TX. Is not mapped north beyond the Lavaca-Colorado Co. line.
