| 摘 要： | 中国冶金地质总局地球物理勘查院在青海巴颜喀拉地区开展了1∶5万高精度航磁测量,项目组通过总结测区内的岩(矿)石磁性规律,分析磁场特征及研究区域成矿模型,精选了部分航磁异常来开展地面查证,取得了较好的金矿找矿效果。本文研究了在青海巴颜喀拉地区、利用高精度航磁测量成果快速高效找寻金矿及有色金属矿的技术方法,总结出不同区域的磁场背景与岩(矿)石磁性特征,其构造破碎蚀变带引起的磁异常并不相同,可能是负磁异常,也可能是正磁异常,并认为研究一个地区的磁异常特征,首先要研究区内的岩(矿)石磁性参数特征。

| Abstract: | This work examined the effect of gold prospecting using aeromagnetic anomalies from high - precision aeromagnetic survey in east BayanHara, Qinghai Province. It is based on magnetism of rocks (ore), features of the regional magnetic field and the mineralization model. The purpose is toexplore how to quickly and efficiently prospect gold and nonferrous metals by applying aeromagnetic survey results in the study area. Summing up differentregional magnetic field backgrounds with different rock magnetic characteristics, this work notes different magnetic anomalies caused by structural alteration zones, which may be negative or positive. Therefore, to study the characteristics of magnetic anomalies in a region, we should first clarify the magnetic parameters of the rocks (ore) in the area. |
