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.Structureless sandstone facies are apparently massive and predominantly fine- to medium-grained, although some are coarse-grained.
