ABSTRACT
The petrochemical and geochemical characteristics of seventeen granitic masses occurring in the Southeastern Desert of Egypt are presented. The average composition of the granite masses accords reasonably well with that of low calcium granite of Turekian & Wedepohl
(1961). The granites have in general pronounced potassic character with some sodic tendencies. Magmatic origin is evident for fifteen granite masses and is based on experimentally studied systems and Ca, Na and K proportions of the analyses.
