Abstract
Sixty-six bottom samples were collected from Khor El-Ramla, Khor Kalabsha, Khor Wadi-Abyad and Khor Allaqi of Lake Nasser. Variations in their grain-size parameters are attributed to the characteristics of the surrounding Precambrian basement rocks and Upper Cretaceous Nubia Sandstone.
The quartz surface texture reflects fingerprints of the original aeolian environment of some grains in spite of the diagenesis effect.
The heavy mineral suite illustrates the prime control of provenance.
The clay fraction is composed mainly of kaolinite and smectite. Illite occurs in traceable amounts. Their distributions suggest a detrital origin.
Geochemical analysis of the clay fraction for SiO2, Al2O3, Fe2O3, CaO, MgO, K2O, Ni, Cu, Pb and Mn content was carried out.
