The method produced a very wide spectrum which cannot be obtained by any other methods. About 20 trace elements have been estimated against the standard Wl. Before activation analysis of the sample an infrared spectrogram was obtained in order to confirm its purity. The studied ilmenite sample was found to contain high chromium content. This could reveal in a decisive way its origin from the basaltic rocks of Ethiopia, Sudan, and Upper Egypt.
