WebThe primary texture and detrital compositions of sandstones, sand body geometry, and architecture, ultimately controlled by depositional environment, are of decisive importance in determining the rate and pathways of fluid flow affecting the extent and distribution of early diagenetic alterations in sandstones [7–12]. WebThe depositional strike paralleled the axis of the basin. The stratigraphic section thins downslope from the fall line, located near what is now Philadelphia. This “tectonic” dispersal system deposited orthoquartzitic conglomerates and lithic sandstones (protoquartzites).

Web(1) Delta-plain sands were moderately sorted and well washed. Original porosity was thus high. (2) Currents also destroyed many mechanically unstable lithic grains, and the resulting sediment became quartz-rich. Consequently, during shallow burial the sandstone suffered just a moderate degree of compaction and porosity loss.
