The Lingos formation, western Rolling Plains of Texas
Lingos strata (Figs. 1, 2) are well exposed at localities in Hall, Briscoe, and Floyd counties, Texas. Except where the formation is dissected or where remnants of bedrock project through it, the Lingos terrane is a smooth continuous geomorphic surface sloping southeastward approximately 80 ft/mi (15 m/km) near the escarpment and 40 ft/mi (7.5 m/km) farther east. The route between the Field Guide localities described here crosses this geomorphic surface, within the area covered by the Plainview sheet of the Geologic Atlas of Texas (Barnes, 1968). However, none of the deposits now recognized as the Lingos formation are shown on the atlas or other maps published before 1984. Topographic maps (7½-minute) covering the localities in this Field Guide are: Turkey, Folley, Quitaque and Lake Theo.
