| Abstract | ||
| Extensive Quaternary deposits are exposed in the Kafr El Gebel region, situated south of the Sphinx in Giza, Egypt. A selection of stratigraphic sections has been made for examination and sampling. To look into the mineralogical and sedimentological features of the Quaternary sediments, samples were gathered. The examined sands are primarily medium to coarse, very well sorted to poorly sorted, and mostly near symmetrical skewed with mesokurtic to leptokurtic features, according to the statistical grain size parameters. The textural features strongly imply that the braided river's fluvial conditions were most likely the primary determinants influencing the movement and accumulation of the sediments under investigation. The majority of the light minerals in the sand under investigation are quartz, with a trace proportion of feldspar. The Quaternary sediments' non-opaque heavy mineral assemblages are typified by the prevalence of pyroxene, rutile, garnet, amphiboles, epidote, zircon, tourmaline, staurolite, and kyanite. A few samples contain andalusite, titanite, and monazite. The ZTR index's low values indicate that these sediments are mineralogically immature. These sediments' rich mineral assem blage suggests a range of likely source rock types, including volcanic, metamorphic, and sedimentary rocks. | ||
