Comprehensive geological study on recent surface sediments of a small North African reservoir, Egypt

The present paper is devoted to throw more light on the geological study of recent surface sediments of a small North African reservoir, as well as, the influence of mother country rocks on these sediments which hasn't been thoroughly studied before. The studied sediments have been confirmed to be mostly derived from Ethiopian sources as indicated by the calculated mineralogic indices, where higher pyroxene index (IPyr = 62.07) was recorded. The Ethiopian Plateau and the local contribution from the surrounding country rocks (Aswan granites, Nubia Sandstone, basement rocks and some volcanic basaltic islands) played the principle role on the distribution of heavy and clay minerals to such sediments.
