Elemental analyses of 10 geological samples from Morocco and some Standard Reference Materials were performed by Energy Dispersion
X-Rays Fluorescence, Wavelength Dispersion X-Rays Fluorescence and Neutron Activation Analysis techniques in order to assess
the accuracy and sensitivity of the concentrations determined with regard to requirements in geochemical exploration. The
possibilities of utilization of EDXRF as an appropriate and economic technique for the analysis of various elements which
are important in interpretation of geochemical data were evaluated.
