摘　　要：结合单人背包式钻机简单便携、对地形要求低与野外X射线荧光测量现场化、快速化、低成本的特点,对西天山航磁异常查证过程中发现的矿化点进行了剖面测量,获得了地表以下4～5 m的矿化信息。与传统槽探相比,该方法没有庞大的工作量,更高效,更经济,并且反应矿化信息深度更深,为野外发现矿致异常并及时追踪和现场异常评价提供了高效的、便利的勘查手段。Since the one-man back rig is simple and portable,it has a low requirement of the terrain and makes the field X-ray fluorescence measurement be on-site,rapid and low cost.The profile survey of the mineralized area is made by field X-ray fluorescence analysis during the process of aeromagnetic anomaly inspection in west Tianshan,obtaining the mineralization information under the surface of 4 to 5 m.Unlike the traditional investigation pit,it is not only more efficient and economic without heavy workload,but also able to gain deeper mineralization information.An efficient and portable exploration method is provided for tracking and evaluating the ore-caused anomalies which are detected in the field work.
