| Abstract: |
| Wadi Aidib lie at southern part of the Eastern Desert of Egypt, between 22o 15' - 22o 21' N and Longitudes 36o 20' - 36o 30' E, covering an area of about 30km2. It is covered by basement rocks dissected by several wadies, Wadi Aidib as a main wadi with several tributaries. Constant of channel maintenance showed the dissection of the studied basin by lineaments, fractures and joints, dissection is minimized in wadi Aidib. Landsat ETM+ false color composite image (bands 3, 2, 1) The rock types wide spread out at Wadi Aidib area contains metavolcanics, alkali feldspar granites, quartz diorites, biotite granites metasediments. Heavy liquid separation and magnetic separation techniques in addition to microscopic examination for the studied stream sediment samples were applied. The mineral resource tonnage for each concerned economic mineral 171.315 ilmenite; 93.150, magnetite; 25.110, zircon; 9.720, total rutile; 7.695, garnet; 1.215, monazite and 810.000 green silicates, in thousands of tons. The studied stream sediments are measured radiometrically using gamma-ray spectrometer for determination the radionuclides contents. U concentration varies between 1 and 2 ppm with 1.69 as an average, Th from 3 to 7 ppm with an average 4.92 ppm. |
