| Abstract | ||||
| Abu Dob monzogranitic pluton occupies the northeastern part of Kadapora batholith which locates in the Central Eastern Desert. Several pegmatitic bodies of different shapes and sizes cut into this pluton. The mineralogical investigation of the monzogranite and pegmatite varieties revealed that the encountered radioactive and strategic minerals can be grouped into; uranium and thorium minerals (uranophane, betauranophane, kasolite, thorite and uranothorite), uranium- and thorium-bearing minerals (samarskite, allanite, monazite, columbite and zircon) and non-radioactive minerals (fluorite, titanite and iron-minerals). On the other hand, the radiometric and chemical investigation of the rocks indicated that the uranium content was affected by addition and removal processes caused the radioactivity disequilibrium and mostly led to the uranium redistribution into the investigated rocks with probable limited migration outside Abu Dob pluton. Also, the recorded uranium mineralization might be of epigenetic origin due to the hydrothermal activity. Both the uranium and thorium elements were not preferentially hosted in the accessory minerals. | ||||
