摘　　要：异常查证的方法种类很多,在查证过程中不可能一一实践,方法选取以及合理综合应用十分复杂并且有严格的特性,需同时考虑地质因素和经济性因素。本文将地面高精度磁法、野外X荧光测量、γ能谱测量等便携、快捷、低成本的方法综合应用于新疆托逊地区航磁异常的查证,发现了三处综合异常区,其中两处是以Cu、Zn为主的多元素异常,均产于负磁异常区并沿断裂带分布,异常强度高、套合好,为矿致异常,对多元素异常区进行踏勘和剥土验证,发现了矿化,对航磁异常查证具有良好的指导意义。There are many kinds of methods for anomaly inspection, and it is impossible to use all of them. Method selection and reasonable usage is a complex process, and has its own rigorous character, which requires considering geological and economic factors. This work integrated applications of the ground high-precision magnetic method, field X-ray fluorescence measurement, and spectroscopy measurement in aeromagnetic anomaly inspection, all of which are portable, fast and low-cost methods, to verify aeromagnetic anomalies in the Tuoxun area, Xinjiang. And three integrated anomaly areas were discovered. Two of them are Cu, Zn-based multi-element anomalies along the fault and neaT＂ the negative magnetic anomaly zone. They are significant a- nomalies because of their high anomaly intensity and perfect anomaly superposition. Reconnaissance and simple engineering verification were conduced in the multi-element anomaly areas, leading to discovery of mineralization. It is of important guidance to aeromagnetic anomaly inspections in other regions.
