Abstract
The granitic masses of Um Huqab, Garf and El-Mueilha Southeastern Desert, Egypt, and belonging to synorogenic, late- and post-orogenic cycles are examined. Petrochemical characters based on major elements data of 13 newly analysed samples are clarified. Behaviour of major elements is discussed and chemical and modal classifications are presented based on normative feldspars and modal composition. Petrographical and petrochepiical data suggest a magmatic origin for the examined granitic rocks. El-Mueilha granitic mass suffered along the peripheral parts, as well as along faults leading to albitization
