مستخلص المنشور

In an attempt to study the reversal application of the uniformitarianism and use of shell
chemistry to emphasize the environmental impacts, chemical analysis of some elements and
oxides for Nerita (Theliostyla) albecil/a, Turbo (Batil/us) radiatus, Cypraea staphylaea,
Clanculus (C.) pharaonius, Conus virgo, Chama pacifica and Amphistegina lessonii in
Pleistocene and Recent sediments along the Red Sea coast, indicated a strongly enrichment of
P,Q, and Zn and relative enrichment of Pb, Cu, Co, Cd, Ni and Mn in Recent sediments of EIHamrawein
area, in comparison with the Pleistocene sediments in the same area, as well as in
Gemsha and Gebel Zeit areas.
The enrichment in concentration of the above mentioned traces and oxides in the study
area were related to the shipping and proccessing of phosphorites, harbor activity, sewage
sludge discharge to the sea and oil industry. As well as the high concentrations of Mn, Ni, Co
and to a lesser extent Cu, which supplied from the mafic rocks of the coastal foreland as a
weathering products.
