航空磁测在喀达塔木地区的应用

The application of aeromagnetic survey in Kadatamu area

西南天山地区地质环境复杂,缺乏全局性、宏观性、系统性的地质工作,物化探工作程度比较低,通过航磁工作结合地面异常查证工作,能够快速的圈定找矿靶区。通过航磁及地面工作,新发现了很多矿化异常区,本文主要介绍其中一处铜铅锌多金属矿异常,航磁异常特征表现为呈平缓波状、两翼对称、梯度变化慢的正异常。

The geological environment of Southwest Tianshan area is complex, lack of overall and geological work macroscopic, systematic, geophysical and geochemical exploration degree is relatively low, the aeromagnetic anomaly survey combined with ground work, can quickly identify the ore target. The aeromagnetic and ground work, found a lot of mineralization anomaly area, this paper presents a Cu Pb Zn polymetallic ore anomaly, aeromagnetic anomaly features a gentle wave, wings of symmetry, gradient slow positive anomaly.
