  3. Tectonics of the Wolf Creek Fault Zone, southern Illinois: A consequence of Late Paleozoic transpression and transtension at the southeastern end of the Ste. Genevieve Fault System

    The Ste. Genevieve Fault System (SGFS) is a 118-mile-long (190 km-long) belt of WNW-trending faults that extends from southwestern-most Illinois, across the Mississippi River, and into southeastern Missouri, in the central (Midwest) United States. East of the Mississippi River, in an area that lies …
