%X Biotites from the granitoid rocks of El-Imra, Eastern Desert, Egypt have been examined. The chemical data of 8 new analyzed biotites are presented. The behaviour of major and trace elements in the examined biotites are discussed according to different variation diagrams. The chemical composition of biotites has proved a reasonable guide to the magmatic origin of the host granitic rocks.
