摘　　要：随着X荧光测量技术的发展,产生了土壤X荧光测量、岩石X荧光测量、钻孔X荧光测量和微区X荧光测量等多种多样的工作方法。笔者将土壤X荧光测量、浅钻X荧光测量和微区X荧光测量等快速获取异常信息手段应用于航磁异常查证,查明特克斯航磁异常主要由富含磁铁矿、褐铁矿的接触带安山岩所引起。对航磁异常查证,乃至找矿勘探工作的高效开展起到了良好的指导意义。As a radiation sampling method,X-ray fluorescence measurement is widely used in ore prospecting for extracting anomaly information in situ. With the development of X-ray fluorescence measurement technology,varied working methods are proposed,such as soil XRF,rock XRF,shallow drill XRF and micro-area XRF. In this paper,soil XRF,shallow drill XRF and micro-area XRF were used for aeromagnetic anomaly survey. The result shows that magnetite and limonite-rich andesite in the contact zone are the main factors responsible for aeromagnetic anomaly in Tekesi,and this result is of good guiding significance for rapid and effective aeromagnetic anomaly verification and ore-prospecting work.
