The Hawkesbury Sandstone is an important groundwater reservoir in the southern part of the Sydney Basin, Australia. However, its diagenesis and provenance and its impact in reservoir quality are virtually unknown. The present study aims to reconstruct the parent rock assemblages of the Hawkesbury Sandstone, their tectonic provenance, and the physiographic conditions under which these sediments were deposited. Samples from the EAW 18a and EDEN 115 field representing the Middle Triassic Hawkesbury Sandstone were studied using a combination of petrographic, mineralogical, and geochemical techniques. The Hawkesbury Sandstone is yellowish brown in color, siliceous, and partly calcareous; it originated as sands …

Petrographic and major and trace element compositions of Tanis sandstones from Tall San Al Hagr, Al Sharqiya Governorate, Egypt, have been investigated to determine their source, provenance, intensity of paleoweathering of the source rocks, and tectonic setting. Tanis sandstones are yellowish brown in color, siliceous, partly calcareous, and originated from sands deposited in fluvial channels. Texturally, Tanis sandstones are medium- to very coarse-grained, mature, and moderately sorted. Scarcity of feldspars indicates that the sandstone is extensively recycled from a distant source. Their average modal composition (Q99.75F0.03L0.22) classifies them as quartz arenites (quartzite), which is consistent with the geochemical study. Chemical …
