From an analysis of the distribution of the types of detrital quartz grains in the Pilliga Sandstone, Arditto (1980) concluded that most of the quartz grains were derived from granitic rocks, and that quartz grains sourced from low- to medium-grade regional metamorphic rocks are of secondary importance.

The 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].
