摘要
本文介绍了可控源音频大地电磁测深法(CSAMT)在秘鲁某矿区水文地质勘察中的应用。通过在矿区开展的5条平行CSAMT剖面和1条垂直CSAMT剖面测量,大致划分了沉积岩地层、火山侵入岩体及复合基底等地层的界线,查明了研究区构造体系和地下水分布特征。本区开展的CSAMT成果与已知地质资料吻合较好,一方面验证了该方法在本矿区水文地质勘察中的有效性和准确性,另一方面揭露了更多深部地球物理信息,对深部找矿具有重要意义。
The paper presented the specific application case of applying CSAMT in hydrogeological survey of a mining area in Peru.Through five parallel CSAMT profiles and one vertical CSAMT profile measurements in the work area,the boundaries of strata such as sedimentary rock strata,volcanic intrusive rocks and composite basement were roughly delineated,while the tectonic system and the characteristics of groundwater distribution in the area were identified.The results of CSAMT in this area were in good agreement with the known geological data,which verified the effectiveness and accuracy of this method in hydrogeological investigation of this mining area.On the other hand,the research results revealed more deep geophysical information,which may be of great significance for deep ore prospecting.
