Abstract: Carter Knox Anticline, an Example of Inversion Tectonics and Fault-Propagation Folding Along the Ancestral Extensional Margin of the Oklahoma Previous HitAulacogenNext Hit, Anadarko Basin

Wendolyn Sumner, Dan L. Hansen, James B. Cearley

The Carter-Knox field, located in the southeastern portion of the Anadarko basin, has a complex growth history controlled by early positioning of the structure along the northeastern edge of the Oklahoma Previous HitAulacogenNext Hit. The Carter-Knox anticline formed by inversion of a bounding normal fault, localized along the ancestral Oklahoma Previous HitAulacogenTop. Northeast-southwest oriented compression, during the post-Hunton Orogeny, caused reverse faulting along the pre-existing basin bounding normal fault, and the development of a moderate relief fault-propagation fold. Subsequent compression during the post-Wichita Orogeny resulted in a high-relief, reverse faulted anticline, with over 8000 ft of vertical separation between the hanging wall and the footwall in the Springer section. Reconstruction of the st uctural growth history was undertaken by sequential subtraction of isopach surfaces in GEOGRAPHIX. Additionally, a series of balanced cross-sections based on well and seismic control was developed and analyzed to determine the sequential growth history of this predominantly compressional structure. Results of this study may serve as an analog for additional exploration along inverted rift margins in compressional settings.
