The Meers fault has been in existence for most of the Phanerozoic. It may have begun as a rift margin fault in the Proterozoic-Cambrian associated with the Southern Oklahoma Aulacogen but its maximum activity took place during the Mississippian and Permian when the Wichita Mountains and the Slick Hills were offset along it by about and the Meers Valley formed along the fault. More fault movements occurred in the Permian and the Pleistocene although there are no post-Permian rock formations in the area that could allow an estimation of post-Paleozoic movements. However, Pleistocene sediments and Holocene alluvium have been offset, indicating fault movement during this time. Recent research has suggested that the whole fault may be of Quaternary age with little activity during the Pennsylvanian. During the history of the fault considerable uplift took place on its southern side while the recent movement has generated an opposite movement.
