西藏藏东地区某航磁异常查证效果

The Verification Effect of Aeromagnetic Anomalies in Eastern Tibet

摘要:

阐述了地物化综合剖面法在西藏藏东地区某航磁异常查证的效果,首先从区域上分析了航磁异常所处的地质背景及其地球物理特征，然后利用地质、物探以及化探综合方法对异常进行了查证，发现了具有一定规模的地表出露铜矿点1处，经定性解释与定量计算，该矿点地物化对应较好且物化探异常明显，表明地物化综合剖面法在该区航磁异常查证中具有良好的找矿效果。

Abstract:

In this paper, the verification effect of aeromagnetic anomalies in eastern Tibet has been introduced by using comprehensive profile method. From regional analysis, geological backgroundand and geophysical characteristics of aeromagnetic anomaly have been analyzed firstly. Combining with geology in anomaly area, aeromagnetic anomalies have been studied furtherly. Then, from the aspects of geology, geophysics and geochemistry, direct ore prospecting results obtained in this verification have been introduced. Qualitative explanation and quantitative calculation of the anomalies have been carried out. It is showed that comprehensive surface profile method has a good effect in verifing the aeromagnetic anomalies.
