Abstract

The area of Wadi Umm Gheig-Umm Naggat is located at the central part of the Eastern desert, Egypt, 50km south to El-Quseir city at the Red Sea coast. The area is dominated by metavolcanics, Older Granites, Dokhan Volcanics, intrusive cumulate gabbro and Younger Granites. This works focuses on heavy minerals distributed in dry stream sediments of Wadi Umm Gheig and Gabal Umm Nagat. The study has followed up the traditional methods for sample collection from the stream sediments and the plane study for investigation and prospecting, as well as evaluation of heavy mineral deposits. The studied bed rocks are represented mainly by monzogranite, alkali feldspar granite, syenogranite and alkali granite. The investigated heavy minerals dominating the stream sediments are given by magnetite, ilmenite, rutile, leucoxene, zircon, fluorite and apatite which are arranged in decreasing order as percentages of abundances. Few trace minerals are detected in some samples like thorite and monazite, and xenotime as well. The evaluation of heavy minerals concentration reveals higher concentration of magnetite, ilmenite and zircon at the western sector, while fluorite show random distributions within the stream sediments area.
