  <dc:description>Three major lithofacies have been identified within the Morrow (Pennsylvanian) and Springer (Pennsylvanian-Mississippian) units, in core from 30 drill holes ranging from the Oklahoma Panhandle to the southwestern portion of the Anadarko basin. The study included inspection of ~6,500 ft of core, examination of ~100 thin sections, and a scanning-electron-microscope study of butts of the material used for thin-section preparation. The lithofacies identified are (1) fluvial-influenced coastal, which includes the deltaic facies described by Swanson (1979), (2) tidal-influenced nearshore, and (3) mixed, which shows mixed tidal and nontidal marine influence. Our interpretation is supported by the investigations of Moore (1979), Haiduk (1987), and Swanson (1979). The fluvial-influenced coastal facies is restricted to the northwestern (Panhandle) portion of the Anadarko basin.</dc:description>
