Paleozoic structural styles and the influence on Early Permian sedimentation in the Midland and Delaware Basins
The influence of basement‐involved fault propagation folding on Early Permian sedimentation patterns can be easily overlooked because faults that caused uplift or base‐level change are often blind thrusts that do not propagate to the intervals they influence. Without the kinematic framework of compressional structures formed during the Wolfcampian and Leonardian intervals, a fundamental control on sedimentation is missed. Furthermore, this requires interpreters to “think regionally, interpret locally” meaning that consideration of the regional structural context is required to better interpret stratigraphic changes within different areas of the basin. The objectives of this presentation are to: (1) highlight structural styles that are common to the Permian Basin and correlate these structures to the timing of key tectonic events; (2) determine the youngest stratigraphic interval that the deeper structures influence; and (3) develop preliminary relationships between the structures and sedimentation patterns within both the Delaware and Midland Basins.
