英文摘要 | Wadi Murrah area is located in the extreme south Eastern Desert of Egypt. The area comprises four distinct tectono-stratigraphic units beginning with the oldest as follows: ophiolitic assemblage (dismembered ophiolitic rocks and ophiolitic melange), arc assemblage (metavolcanics, metagabbros, and older granites), post-collision granitoids (monzogranite, syenogranite, and alkali feldspar granite), and associatedwith dykes and quartz veins. The identifiedminerals in the samples taken from the anomalous sites of syenogranite and alkali feldspar granite in the northern part of the study area are represented by uranophane, autonite, meta-autonite, uranothorit, columbite, zircon, fluorite, monazite, xenotime, sphene, allanite, and apatite. The anomalous samples have U and Th average contents for syenogranites and alkali feldspar granites 82 and 104.4 ppm and 209 and 115.2 ppm, respectively. The high radioactivity in the anomalous sites is controlled lithologically and structurally. The secondary processes played a main role in uranium enrichment (uranium added to these granitic sites post-magmatically). |
