Geochemical studies of some granites from the South Western Desert, Egypt
The present work is the first detailed petrochemical and geochemical studies done on some 18 granitic rocks collected from the south Western Desert of Egypt. The petrochemical work includes complete chemical analyses of these rocks beside calculation of the CIPW norms,- NIGGLI values, D. I. , F. I....

| 520 | 3 | |a The present work is the first detailed petrochemical and geochemical studies done on some 18 granitic rocks collected from the south Western Desert of Egypt. The petrochemical work includes complete chemical analyses of these rocks beside calculation of the CIPW norms,- NIGGLI values, D. I. , F. I. and M . I. Thirteen trace elements are quantitatively determined, these are: Ba, Rb, Sr, Y, Zr, Nb, La, Ce, Nd, Cr, Ni, Zn and Cu. These chemical studies established the presence of five rock types: grey granite, Aswan-type granite, normal pink-red granite, strongly fractionated pink-red granite and syenite.'It is concluded that the basement rocks of Egypt developed in the Eastern Desert and Sinai peninsula are extended across the Nile, mostly subsurface, in the southern parts of the Western Desert. To the first time, Aswan coarse granites are proved to occur in the south Western Desert. This makes them of much wider aereal distribution than previously known. On account of their peculiar chemical composition, Aswan plutonites can be grouped in a separate plutonic cycle. | |
