云南镇康芦子园铅锌铁矿床位于西南三江保山—镇康成矿带南段，地质构造复杂，多期次构造岩浆活动发育，成矿地质条件优越。经矿区重力、航磁及地质等综合资料分析，认为芦子园地区存在隐伏酸性岩体。为查明隐伏岩体的分布特征、起伏形态及埋深，本次研究使用了大地电磁法（AMT）和重力三维反演方法。通过重力三维反演图可以看出芦子园地区隐伏岩体的分布情况及其形态；通过 AMT 二维反演反映出深部地质构造及隐伏岩体形态及埋深。结合地质资料，综合研究了岩体与地表、近地表的铁铅锌矿化关系，为深部找矿指出了方向，进一步指导勘查区的深部找矿工作。

Located in the southern part of the Baoshan-Zhenkang metallogenic belt, the Zhenkangluziyuan lead-zinc and iron ore de?posit of Yunnan possesses a complex geological structure, well?developed multi?stage tectonic magmatic activity, and an excellent met?allogenic conditions. Years of comprehensive study and gravity, aeromagnetic and geological exploitation indicate that there exists a con?cealed rock body in the Luziyuan area. To identify the distribution, undulating shape and depth of the concealed rock body, the authors used the magnetotelluric method (AMT) and three?dimensional gravity inversion method. The distribution and undulating shape of the concealed rock body can be detected by the three?dimensional gravity inversion. The AMT dimensional inversion reflects the deep geo?logical structure and the undulating shape and depth of the concealed rock body. Combined with geological data as well as a comprehen?sive study of the relationship between the concealed rock body and the lead and zinc iron mineralization at surface and in near?surface place, the authors point out the deep prospecting direction, which provides further guidance for deep prospecting in the exploration are?a.
