Using Landsat Thematic Mapper Data for Structural Analysis of Slick Hills Area, Southwest Oklahoma

Steven J. Wilhelm, Ken M. Morgan

In this study, we used Landsat Thematic Mapper (TM) data to identify structural lineaments in the highly deformed Slick Hills area of southwestern Oklahoma. These low-lying hills represent a sequence of Cambrian-Ordovician rocks (primarily carbonates) that were intensely folded and faulted during the Pennsylvanian and Early Permian.

Our analysis of Landsat TM computer-generated images (scale, 1:70,000) revealed two major lineament orientations from rose diagram plots. One set of lineaments trends N30°-60°W and is associated with left-lateral, thrust, and high-angle reverse faults. These faults, as well as fold axes and fracture patterns, dominate the study area and are well documented in the literature.
