The collected wadi deposit samples (24 samples) from Gabal El-Dob area, at the northern part of the Eastern Desert of Egypt are subjected to mineralogical and chemical analyses. Generally, they are classified into light and heavy minerals. The light minerals are mainly quartz and feldspars. The heavy minerals are divided into magnetic and non-magnetic minerals. The magnetic minerals are represented mainly by magnetite, however the non-magnetic ones are classified into metallic and non-metallic

However, the non-metallic minerals are represented by zircon, apatite, monazite and garnet with addition to mafic minerals (biotite, hornblende, epidote and chlorite). The occurrence and distribution proved also that they had been formed by weathering action of fresh water (rivers) rather than beaches, nearby the outcrops of rock sources.
