摘要
文章在综合甘肃阳山金矿区物化探方法已有成果基础上,选择可控源音频大地电磁测深(controlled source audio-frequency magnetotellurics,CSAMT)、大功率激电(induced polarization,IP)、地面高精度磁法及构造叠加晕等方法在主要成矿地段开展应用研究,对各方法应用效果进行了分析评价,建立了矿区深部勘查方法组合及应用流程。研究成果可为矿区深部和外围勘查以及类似地区金矿勘查方法的精准实施提供参考。
In this paper,based on the previous results of geophysical and geochemical survey methods for the mining area of the Yangshan gold belt in Gansu Province,the methods of controlled source audio-frequency magnetotellurics(CSAMT),high power induced polarization(IP),ground high precision magnetic survey and structural superimposed halo are selected to carry out application research in the main metallogenic areas.The application effect of each method is analyzed and evaluated.On this basis,the combination and process of deep prospecting methods for the mining area are established,which provides a reference for the deep and peripheral prospecting of the mining area and accurate implementation of prospecting methods for gold deposit in similar areas.
