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, Al 2 O 3 3, SiO 2 , P 2 O 5 , K 2 O, CaO, TiO 2 , MnO, Fe 2 O 3 ) 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.
