Van Buren and Lavaca quadrangles cover an area of about 488 sq miles in E.-central Oklahoma and W.-central Arkansas. Rocks of Middle Pennsylvanian age and unconsolidated alluvial deposits of Quaternary age are exposed at the surface, and rocks of Ordovician to Middle Pennsylvanian age have been penetrated by wells drilled in the area. The rocks have been folded into E.-trending broad, gentle folds whose limbs have been broken by N.- or S.-dipping normal faults. Displacement across the faults is generally less than 1,500 ft, but may be as much as 2,500 ft. The Atoka, McAlester, and Savanna formations contain coal beds. The Lower Hartshorne coal bed, near the base of the McAlester Formation, and the Charleston coal bed, near the base of the Savanna Formation, have been the most economically important. Natural gas has been found in rocks of Silurian, Devonian, Mississippian, and Pennsylvanian age. Most of the gas is in rocks of Pennsylvanian age, in the Atoka Formation. The gas in Pennsylvanian rocks is lithologically entrapped, and structure appears to have had little influence on the location or extent of gas accumulation. (30 refs.)
