HALEY and THOMAS A. HENDRICKS ABSTRACT coal beds, and to present estimates of coal resources Van Buren and Lavaca quadrangles cover an area of about where data permit; (4) to provide geologic data and the 488 square miles in east-central Oklahoma and west-central authors' interpretations of these data relevant to the Arkansas. Rocks of Middle Pennsylvanian age and unconsoli- accumulation of natural gas; and (5) to provide infor dated alluvial deposits of Quaternary age are exposed at the mation about the availability of building stone, gravel, surface, and rocks of Ordovician to Middle Pennsylvanian age have been penetrated by wells drilled in the area. sand, and clay. The rocks have been folded into east-trending broad, gentle This report together with added lithologic descrip folds whose limbs have been broken by north- or south-dipping tions of rocks penetrated by selected wells and shallow normal faults. Displacement across the faults is generally less holes is also published, under separate cover, as Arkansas than 1,500 feet but may be as much as 2,500 feet across the fault Geological Commission Information Circular 20-1. that separates the Arkansas Valley section from the Ozark Plateaus province. Folding and faulting started on a major scale The Van Buren quadrangle (lat 35°15' and 35°30' N., during the deposition of the Atoka Formation and continued long 94°15' and 94°30' W.) has an area of about 244 until after deposition of the youngest Pennsylvanian beds. The square miles, of which about 60 square miles is in Le structural relief in the report area, as measured on the base of Flore and Sequoyah Counties, Okla., and about 184 the Hartshorne Sandstone, may be as much as 4,450 feet. square miles is in Sebastian and Crawford Counties, The Atoka, McAlester, and Savanna Formations contain coal beds. The Lower Hartshorne coal bed, near the base of the Ark. The Lavaca quadrangle (lat 35°15' and 35°30' N., McAlester Formation, and the Charleston coal bed, near the base long 94°00' and 94°15' W.) adjoins the Van Buren quad of the Savanna Formation, have been the most economically rangle on the east. It has an area of about 244 square important. miles in Sebastian, Franklin, and Crawford Counties, Natural gas has been found in rocks of Silurian, Devonian, Ark. (fig. 1). Mississippian, and Pennsylvanian age. Most of the gas is in rocks of Pennsylvanian age, in the Atoka Formation. The gas Generalized geologic reports pertaining in part to the in Pennsylvanian rocks is lithologically entrapped, and structure Van Buren and Lavaca quadrangles have been made by appears to have had little influence on the location or extent of Winslow (1888), Smith (1914), Croneis (1930), and gas accumulation. Haley (1960) for the Arkansas part, and by Drake Building stone and road metal have been obtained from the Atoka, Hartshorne, McAlester, and Savanna Formations. Gravel (1897), Taff and Adams (1900), Taff (1905), Snider and sand are obtained from the alluvial deposits, and the shale (1914), Smith (1914), and Shannon and others (1926) in the McAlester Formation has been quarried for brick and tile. for the Oklahoma part.
