Analysis of Egyptian Geological Survey and Mining Department samples by rapid rock and atomic absorption procedures

A suite of 165 samples from the Egyptian Geological Survey and Mining Department was analyzed for several elements in the Branch of Analytical Laboratories (BAL) of the U.S. Geological Survey by M. Iskander and S. Holyle during training here that focused on rapid-rock analytical procedures and on atomic-absorption spectrometric analyses. Because the training period was too brief to complete all required analyses on these samples, members of the BAL did additional determinations. These materials will serve as control samples when the newly learned techniques are implemented at the Cairo laboratory by M. Iskander and S. Holyle.
