Popis: An X-ray fluorescence spectrometer (Philips PW1404) equipped with a scandium anode tube was tested for major element analysis of rock samples. Rock powder, five times flux (Li2B4O7), and 20 to 30mg of LiBr・H2O were mixed and fused to make a glass bead. The calibration lines were determined from 13 rock standards of GSJ and USGS and 14 synthetic standards by using a software X44 for the PW1404. The synthetic standards were useful in estimating of the matrix correction factors, and adequate calibration lines were provided for a wide range of composition. The analytical errors of the calibration lines were enough small for the purpose of petrological investigations. Using an automatic sample changer PW1500 and a software X44 for XRF, more than 80 rock samples can be automatically analyzed in a day. This method is suitable for the routine work of major element analysis of rock samples.
