The Gattar granites are composed mainly of quartz and feldspars as essential minerals and biotite hornblende, zircon, apatite and sphene as accessory minerals, some secondary minerals as epidote, chlorite and sericite are found. The Gattar granites originated from calc-alkaline magma and tectonically it is volcanic arc granites. The study includes some mineral as feldspars, biotite and, amphiboles from Wadi Balli under Environmental Scanning electron Microscopy (ESEM) attached by Energy Dispersive E-ray analyses (EDX) in nuclear Materials Authority (NMA), gave that the feldspars composed under temperature 850ºC and biotite in Wadi Balli originated from magmatic origin.
