The Ouachita Mountains located on the eastern side of the North American within the Appalachian Mountains is a continental crust against a continental crust formation that exhibits large thrust faults with horizontal breaks. These compressional thrust faults create folding in the sedimentary rock. Layered waves of sedimentary rocks to include sandstone, shale, and chert show evidence of when Gondwanaland collided with the southern edge of ancient North America to form the Ouachita Mountains.
