Abstract
The uranium occurrence in Gebel El Missikat has been the subject of several exploration programs since it discovery in 1972 with no consolidated results to evaluate this prospect. The present study is a trail to aooly systematic intergated work to decipher the U-potentiality of El Missikat-Gidami granite pluton and surrounding Nubia Sandstone contacts. The area is located in the centeral Eastern Destet of Egypt, South of Quena- Quseir road , between longitudes 33˚15’ -33˚ 28’E and latitudes 26˚ 24’_26˚ 30’N. The study includes, besides revising the previous works, geological re-mapping , ground gamma spectrometric mapping of the radioelements, geochemical. petrographical, and mineral chemistry diagnostic studies The area is evaluated taking into consideration the successful exploration concepts and recent scientific criteria of U-fertile granites applied in the Central Massif of France and in Canada. This work comes• out as a part of the exploration studies programs of the Studies , Dept. at the Nuclear Materials Authority of Egypt (NMA) and the conjunction Model Project ”EGY/3/014” sponsored by the NMA and the International Atomic Energy Agency (IAEA) for U-resources in the Eastern Desert of Egypt. The geologic study, presents a new geologic map of the area. It indicate that the area is composed of circular outcrops of younger granite (EI Missikat-Gidami YG pluton, 580Ma) with NE-SW trending aploporphyry dike swarm at its northwestern periphery intruded into older country rocks of mainly granodioritic older granitoids (OG) and some metavo1canics. These basement rocks are unconformablly overlain to the west by ”Nubia Sandslone ” of Early Cretaceous age. Phologeological and field observations separate EI Missikat-Gidami YG in the area into four magmatic phases. These phases start by the aploporphyry dike swarm at the northwestern contacts of the pluton and three concentric phases in the pluton; MG1 peripheral phase followed by MG2 which form the bulk of the pluton and MG3 at the core.
