Conclusions
Mudstones to sponge spicule wacke-packestones were deposited in T-R cycles on a shelf to shelf margin setting in a series of shallowing upward cycles
Early silicification, inter- and post-Mississippian subaerial exposure resulted in sponge spicule dissolution, vuggy porosity development in moldic rich rocks, and autobrecciation
Areas of increased diagenesis can be correlated with basement lineaments and recurrent block movement
Meteoric water influx, or the range of the mixing zone controlling diagenesis, appears to have been limited in depth below the exposure surface and in depth downdip into unaltered cherty Cowley Formation facies
Combination of block fault movement, sponge spicule concentration, and possibly thickness of overlying bioclastic wacke-grainstones resulted in variable reservoir properties and the creation of pods of production separated by non-productive cherty dolomite mudstones
These events also resulted in alteration of the depositional cycles to produce a series of lithofacies which each exhibit relatively unique petrophysical properties
