The Ouachita Mountains record the late Paleozoic Laurentia-Gondwana orogenic event along southern Paleo-North America during Pangea supercontinent formation. This data release contains a digital compilation of geomorphic-structural information from the Ouachita Mountains of southeastern Oklahoma and southwestern Arkansas as previously published by Arbenz (2008). The geodatabase, presented herein, contains feature classes that include contact, fault, fold, and cross section lines with map unit polygons characterized by predominantly siliciclastic material with primarily Paleozoic depositional ages. Spatial data are also disseminated as shapefiles, accompanied by applicable non-spatial tables detailing the data sources, glossary of terms, and description of map unit information.
