The amount of material usually required for X-ray fluorescene analysis of briquetted rock powders is of the order of 2 to 3 g. By reducing the diameter of the pellets and the cross-section of the incident X-ray beam, it is possible to analyse a small quantity of material (about 40 mg) reliably. The results obtained from the analysis of about 40 mg of powder for the major components (MgO, Al2O33, SiO2, P2O5, K2O, CaO, TiO2, MnO, Fe2O3) and for 12 trace elements (Cr, Ni, Cu, Zn, Ga, Rb, Sr, Zr, La, Ce, Ba, Pb) in 6 standard samples of rocks (US Geological Survey Standards: G-2, GSP-1, AGV-1, BCR-1, DTS-1 and PCC-1) are reported. These data are compared with those obtained from standard pellets and from literature values.
