Field investigations in the Lake Classen-Turner Falls, Oklahoma, area of the northern Arbuckle anticline, on the southeastern margin of the Anadarko basin, indicate that transpressional (oblique compressional) deformation of Late Pennsylvanian age dominated the structural development of this area. The Arbuckle anticline is detached along the NW -trending, SW -dipping, left-reverse Arbuckle fault and is thrust obliquely onto the margin of the Tishomingo block to the east. Paleostress analysis of slip lines on mesoscopic faults along the northeastern limb of the Arbuckle anticline, associated in style and geometry with oblique Arbuckle thrusting, indicates compression directed N. 35-60° E.
