We present an accurate method for determining the concentrations of the major and minor elements in iron-rich and other geological samples using the X-ray fluorescence analysis. A fusion method was used for sample preparation. We used theoretical alpha coefficients which we calculated in order to correct for any matrix effects. For an on-line analysis, we re-calculated the theoretical alpha coefficients using transformation formulas. The analytical results show that the theoretical alpha
