Basement Influence on the Structural Geology of Southern Oklahoma Inferred from Residual Aeromagnetic Maps

THOMPSON, THOMAS L., Geo Discovery, Inc., Boulder, CO, S. PARKER GAY, Applied Geophysics Inc., Salt Lake City, UT, BRONSON HAWLEY, No affiliation, and JAMES R. HOWE, Consultant, Boulder, CO

This poster display illustrates magnetic basement control on the structural pattern of southern Oklahoma with a few examples of its influence on petroleum accumulation, including potential fracture reservoirs (i.e., Arbuckle, Viola-Bigfork, Woodford-Arkansas novaculite formations, etc.). Exploration for fractured petroleum reservoirs requires knowledge of structural dynamics, structural mechanics, and present state of stress as well as paleostress.

High-resolution residual aeromagnetic mapping provides a particularly useful display of areal continuity of basement block pattern that, when considered in context of tectonic plate movements, allows predictions of specific fault reactivation, timing, and sense of displacement. Study of aeromagnetics often provides better understanding, downward and lateral projection of known faults, support for suspected faults, and inference of previously unrecognized faults.
