Upper Pennsylvanian rocks bordering positive features near Bartlesville, Oklahoma, contain a variety of examples of preconsolidation deformation. The deformation can be attributed to anticlinal growth during deposition but, more specifically, some of the disturbance structures are consistent with, or best explained by, an earthquake origin. Fath proposed that anticlines and domes in the Mid-Continent grew during Pennsylvanian and Permian times through movement along fault zones in basement rocks. The evidence of earthquake deformation in the Bartlesville area supports this hypothesis.
