Geochemical Characteristics and Implications of The Provenance of Abu-Shaybah Formation Sandstones Wadi Greem Area in Al-Khums City

الملخص

The Abu-Shaybah Formation (Late Triassic) is separated into the lower and upper sections and has an unconformable relationship with the Alaziziya Formation. We looked into the main components of the formation in this study. The samples had moderate concentrations of SiO₂ and Al₂O₃, with average values of 87% and 8.7%, respectively, according to the Sandstone geochemical data. and greater amounts of Fe₂O₃ (3.1%), TiO₂ (0.21%), and the element's contents of MnO, K₂O, MgO, Na₂O, and SO₃ were around (0.1%), with P₂O₅ (0.05%) having the lowest value. Because calcite is used as a cementing agent, the CaO content of these sandstones is approximately 0.8%. Relevant geochemical element plots show that the majority of the sandstones in Abu-Shaybah are Quartz arenite kinds.
