However, the secondary porosity seen in most ancient sandstones is the product of burial diagenesis. Permeability measures the ease with which a fluid flows through sediment or rock. The flow of fluid from one part of a rock to another, or from an aquifer to a bore hole, depends on the connections among pores and fractures.

The lower Muddy sandstones are preserved as infill of a dendritic channel system which was incised into the Skull Creek Shale during an earlier period of emergence. The sand was supplied from the delta to the northeast and transported to the south by longshore currents.
