Abstract.

 

Twenty one new chemical analyses of the granitic rocks of Umm Naggat, Eastern Desert, Egypt, are presented and discussed. Chemical data are processed into several parameters which indicate that these rocks show pronounced potassic characters with some sodic tendencies. The granitic rocks are calcic to calc-alkaline with a suite index between 1 and 3, and a calc-alkali index of about 60. These rocks show chemical variation trends suggesting a highly differentiated magma. It is argued that the Umm Naggat pluton is possibly of magmatic origin. A chemical classification of the granitic rocks based on their normative feldspars is also advanced.
