Abstract
Two groups of granitic rocks are exposed in the Wadi El-Rahaba area: the older of which is chemically metaluminous, depleted in Nb and subduction related, whereas the younger is metaluminous to peraluminous, enriched in Nb and intraplate, an orogenic granite formed through partial melting of lower crustal materials.
