Fan deltas prograded repeatedly onto a shallow, carbonate-shelf environment in the Anadarko basin during Late Pennsylvanian (Missourian) time. These fan-delta sandstones were part of a thick wedge of coarse clastics which were derived from the Amarillo uplift. Similar fault-bounded basement uplifts found throughout the west-central United States at this time formed an intracratonic tectonic setting in which alluvial-fan and fan-delta sedimentation was common. Missourian reservoirs at Mobeetie field consist of three alternating limestone and sandstone units. Limestones accumulated along strike in elongate, phylloid-algal mounds that separated the open shelf from a more restricted lagoonal environment. Algal-mound cores consist of a algae-foraminifer wackestone and packstone, and mounds are capped by coral boundstone and encrusting algae-foraminifer wackestone. Progradation of coarse-grained terrigenous clastics onto the carbonate shelf halted carbonate production. Braided streams breached low areas along the algal-mound trend and deposited fan-delta sediments on the shelf basinward of the mounds. Distal-fan-delta deposits in the two younger sandstones were reworked along strike into spits and bars. Carbonate deposition recommenced following waning of clastic influx and subsidence of the fan-delta sediments. Algal mounds were reestablished preferentially on shallow platforms formed by terrigenous clastics of the previous cycle. 22 figures, 1 table.
