Abstract Research was carried out under the special conditions of the Tibetan Plateau, with the consideration of the time-costing feature of regional geochemical follow-up. The portable XRF spectrometer was used in the research, and the instrument was calibrated and checked for the stability. The sample particle size of -160 mesh for sample processing and powder samples was determined. The result of in-situ experiment, which was conducted in Yazhuo anomaly follow-up zone, is basically in accordance with the conclusion of laboratory analysis. This is an in-situ analytical method, which can quickly provide analytical results and effectively shorten the work period for anomaly follow-up.
