Mineralogical Studies and Radioactivity on Stream Sediments Around Wadi Aidib Area, South Eastern Desert, Egypt

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