Geometry of Late Paleozoic Thrusting, Wilburton and Damon Quadrangles, Arkoma Basin, Southeast Oklahom

Abstract

This study was aimed at determining the structural geometry of the transitions zone between the Ouachita Mountains and the Arkoma Basin, and better understand the subsurface geometry of the triangle zone in the Wilburton and Damon Quadrangles, Arkoma Basin, Southeastern Oklahoma. Five structural cross-sections, two structural contour maps, two cumulative gas production maps, and a topographic map were constructed. From the study, it was determined that a duplex structure composed of three horses marked the structural geometry of the transition zone in the Wilburton and Damon Quadrangles. To the west of the study area, the south dipping Choctaw fault and the north dipping Carbon fault form a triangle zone. A lateral ramp causes an offset in the duplex structure, and a possible displacement of the triangle zone.
