摘要
本文通过对桂滇黔地区高精度航磁资料研究,尤其是对已知微细粒型金矿区的磁场特征分析,发现在多数金矿区及附近存在航磁异常。结合物性等资料认为磁异常主要是基性岩的反映,因此金矿与基性岩的关系密切。利用航磁并结合其他资料,可以间接圈定寻找金矿的靶区。
Based on an investigation of high-precision aeromagnatic data of Guangxi-YunnanGuizhou region and, especially, an analysis of magnetic field characteristics of micro-grained gold districts, the anchors have found that there exist aeromagnetic anomalies in or near most gold districts. Such a phenomenon combined with phwical property data has led to the understanding that magnetic anomalies are mainly reflections of basic rocks, ac hence gold deposits are closely related to basic rocks. Using aeromagotic data together with some other data, one may indirectly delineate target areas for gold deposits.
