The Delaware Basin is the larger of the two major lobes of the Permian Basin within the foreland of the Ouachita–Marathon thrust belt separated by the Central Basin Platform.
The basin contains sediment dating to Pennsylvanian, Wolfcampian (Wolfcamp Formation), Leonardian (Avalon Shale), and early Guadalupian times.
The eastward-dipping Delaware basin is subdivided into several formations (Figure 2) and contains approximately 25,000 feet (7,600 m) of laminated siltstone and sandstone.
Aside from clastic sediment, the Delaware basin also contains carbonate deposits of the Delaware Group, originating from the Guadalupian times when the Hovey Channel allowed access from the sea into the basin.
