Abstract  

Fourteen clay samples separated from calcareous, lacustrine, Nile alluvium and desert alluvium soils of Egypt were analyzed by pure instrumental neutron activation analysis. Elemental composition was determined by high resolution gamma-spectrometry on samples irradiated with reactor neutrons using the monostrandard technique. This was carried out in the nuclear research center of Karlsruhe, West Germany. As many as 17 trace elements, beside Ca, K, and Na, were quantitatively determined. The spectra of chosen activated clays are given. Data reveal that the content of the trace elements As, Cs, Hf, Sb, Sc, Sm, Yb, Th and U were found within a narrow range despite location and depths of clay samples. Nevertheless, the contents of some elements mainly Ce, Cr and La had a wide range. In brief, the presence of any elements in higher or lower levels in certain clays is contingent on the occurence of its bearing minerals, nature of parent sediments and depositional environments of these sediments.
