The geological mapping, landstat images, and detailed sedimentological analysis through measurements of 10 stratigraphic columnar sections, have revealed the presence of four facies associations among the Pre-Eonile and Eonile sediments along the Egyptian Nile west of Sohag. These reflect the co-effect of local and regional tectonics, changes of the catchment areas and paleoclimatology, and were related to four successive tectono-sedimentary ... Read more

In this study, mine tailings located in different climatic regions were studied for their mineralogical, geochemical, physical properties and the tailings discharge techniques used to understand the process affecting hardpan formation. This was combined with column experiments for monitoring the transport/precipitation processes. Thickened tailings discharge in Egypt did not allow grain-size/mineral segregation and therefore the critical amount of reactive mineral ... Read more
