祁门地区航磁异常特征及找矿方向

利用祁门地区1:10高精度航磁资料,结合区域地质背景分析了该区航磁异常特征,并结合物性,分析了航磁异常的地质成因及其对地质构造和成矿的反映。通过对祁门地区航磁异常筛选,提出重点异常查证,发现了1处大型斑岩钨矿及多处有色金属、贵金属矿点,在此基础上总结了本区航磁异常与成矿之间关系,提出了今后利用航磁异常在本区的找矿方向。

Characteristics of Aeromagnetic Anomalies in Qimen Area and the Prospecting Direction

With the 1：10 high precision aeromagnetic data from Qimen area, combined with regional geological background, this paper analyzes the characteristics of aeromagnetic anomalies, and expolres the geological origin of and its reflection to geological structure and mineralization by combining with the physical properties. Through the screening of the aeromagnetic anomalies in Qimen region, it proposes the key anomaly inspection, finds one large porphyry tungsten and multiple nonferrous metal, noble metal mine, on the basis sums up the relationship between aeromagnetic anomalies and mineralization, and puts forward the future prospecting direction by the use of aeromagnetic anomalies.
