A Midwestern Province: Abstract
One of the most important tectonic features of the Southwest United States is the Ouachita Structural Province. The known length of the folded eugeosyncline is 1350 miles, with much of the Pennsylvanian and Mississippian prism of sediments which comprise it buried, although extensive outcrops occur in the Ouachita area of Oklahoma and in the Marathon area of Texas. A regional gravity assembly delineates the trend of the bast feature, and regional magnetic maps assist in further interpretation. The feature has had a controlling effect on the subsequent deformation of overlying sediments; the rocks of the Ouachita feature are complexly faulted and folded and constitute a productive province.
