[en] The exploration activities carried out by the nuclear materials corporation in gebel gattar area revealed the presence of some uranium mineralizations within the gattar granite. The present work deals with the mineralogic studies of some mineralized surface samples of this granite. X-ray diffraction indicated the presence of a wide variety of uranium minerals, namely uraninite, clarkeite, zippeite, umohoite, carnotite as well as uranophane, soddyite, kasolite and becquerelite. Further more detailed work concerning the mineralogy of deeper samples from this promising uranium occurrence is recommended
