...W. G. Brown Abstract With the application of plate tectonic concepts to southern Oklahoma, the structural style has more recently been characterized as a wrench fault system. In particular, the Washita Valley fault (WVF) is generally considered by many geologists to be a major left-lateral strike...

...J. Henry Tanner The Washita Valley fault is the most significant fault in the Arbuckle Mountain area of southern Oklahoma ( Fig. 1 ). It is traceable on the surface for approximately 35 miles. Its southeastern extension plunges beneath the Cretaceous overlap where it is traceable...

...Molly Turko; Bryan Tapp Abstract We propose that the Washita Valley Fault in the southeast Anadarko Basin originated when Precambrian-Cambrian preexisting rift-related faults became reactivated as a rotational stress field reached a favorable orientation for strike-slip displacement. During...

...Deanna L. Palladino Abstract The Washita Valley fault zone is one of the major northwest-trending structures in southern Oklahoma. This fault system is believed to have originated as a series of normal faults during the formation of the southern Oklahoma aulacogen by late Precambrian or early...

... and Marietta-Sherman basins are characterized by large northwest-trending strike-slip faults. The best examples of these are the Reagan and Washita Valley faults which bound the Tishomingo uplift on the northeast and southwest, and the Mannsville-Madill-Aylesworth fault which parallels the Washita Valley fault...

... in the Middle Pennsylvanian. Slides and faults were subsequently isoclinally folded in the Late Pennsylvanian. The tensional updip segment of the major folded slide fault now coincides with the trace of the Washita Valley fault. The compressional end of the slide coincides with the Reagan fault in the east...

... interpretation concerns the nature of the northwest-trending through-going faults, principally the Washita Valley fault, Reagan fault, and the Sulphur fault zone. These have been variously interpreted as normal, thrust, scissor, and rift faults. Dips observed or inferred on the outcrop, together with information...

...Bruce H. Harlton ABSTRACT The eastern prolongation of the Tishomingo horst in Atoka and Bryan Counties, Oklahoma, is bounded by two large northwest-trending faults. The Sulphur fault bounds the northeastern side and the Washita Valley fault-complex zone the southwestern side. The two faults, which...

... (Ramelli and Slemmons, in press). At least four fault zones in other parts of CEUS indicate that the Meers faulting event is not unique, including: (1) New Madrid epicentral region with three events of about M S = 8 in 1811 and 1812 with surface faulting and deformation (Russ, 1982), (2) Washita Valley...

... within the study area have trends and slip directions that are generally similar to those within the Reagan and Washita Valley fault zones in the Arbuckle uplift adjacent to the Anadarko basin. The difference in the style of deformation between the two uplifts relates to varied angular relationships...

... folded into generally parallel, overturned anticlines and synclines. Somewhat later the overturned folds were broken by many branching faults, and fold axes were displaced as much as a mile. All the faults probably are branches of the Timbered Hills-Washita Valley fault. Most are strike- or oblique-slip...
