Post-Pliocene movement along the Texas lineament is indicated by analysis of regional joint-fracture-fault systems in northwestern Chihuahua, Mexico, and on the southern High Plains, Texas.

The southern High Plains, Texas, show evidence of a regional force couple created by stresses along the Texas lineament on the south and the Wichita lineament on the north. Pleistocene to Holocene stresses along the Texas lineament have been right-lateral, but the Llano Estacado of West Texas exhibits evidence of both right- and left-lateral stresses along the Wichita lineament.
