Tartalmi kivonat:The granitic plutonism in the area around Wadi El-Sheikh, southwestern Sinai, Egypt is mainly represented by the Older and Younger Granitoid Rocks. The younger granitic rocks comprise in turn, two granitic phases, distinguished on field basis. Morphological characters of zircon concentrates from the examined rocks have been statistically studied. Zircon populations in the Older Granitoids contain a wide variety of crystal shapes while in those of the younger granitic rocks, zircon crystals become prograssively more uniform in morphology. Distinction between zircons of the Older and Younger Granitoids is based mainly on their dimensional parameters. Similarity of the dimensional parameters of zirkons in the younger granitic phases renders their separation difficult. The significance of zircon as a guide to the pedogenesis of Wadi El-Sheikh granitoids is ascertained.
