Distribution and properties of placer ilmenite in Damietta-Port Said beach sands, Egypt [elektronikus dokumentum] / Wassef Samir N. University of Szeged, Department of Mineralogy, Geochemistry and Petrology Szeged 1985 131-138 Acta mineralogica-petrographica 27 This work deals with a comprehensive study of ilmenite distribution in the sands of DamiettaPort Said beach which is a part of the African Coast on Mediterranean Sea. This area extends for about 36 km to the east of Damietta Nile branch estuary, and of about 11 km2 The sands come out of the estuary and subjected to northwesterly winds, and a current parallel to the beach line from west to east. These conditions cause the accumulation of heavy minerals bearing ilmenite on the eastern side of Damietta estuary. Systematic withdrawal of 116 auger samples distributed regularly on the beach stretch have been analyzed for ilmenite. The tenor of ilmenite was found to vary between 5.82% and 15.328% and concentrates in three main locations. The upper meter showed a reserve of about 1.23 million dry tons of ilmenite. Ilmenite is characterized by the presence of hematite, rutile, magnetite as exsolutions and decomposition into different alteration products is recorded. The presence of ilmenite besides zircon and rutile is suggesting the Precambrian and basic plutonic rocks provenances drained by the highlands of the River Nile in Africa. The high chromium content in ilmenite relates its origin to the basaltic rocks in Ethiopia, Sudan and Upper Egypt.
