| 中文摘要: |
| 个旧超大型锡多金属矿床开采历史悠久，成矿作用和矿化类型复杂多样。随着浅部资源的消耗，如何寻找深部接触交代矽卡岩型锡多金属矿和层间硫化物型锡多金属矿，成为个旧高松矿田亟待解决的重要课题。为推动高松矿田中深部找矿突破，本文将广域电磁法应用到高松矿田进行深部探测，查明了深部地质体的分布形态；综合分析了矿田成矿地质特征，总结了矽卡岩型矿体和层间硫化物型矿体的矿床地质特征；同时结合广域视电阻率特征，建立了高松矿田两种主要矿床类型的地质-地球物理模型，以此模型进行成矿有利区预测，可为个旧地区及国内其他类似多金属矿的地球物理勘探提供参考和借鉴。 |
| 英文摘要: |
| The super large tin polymetallic deposit in Gejiu has a long mining history， the ore-forming process and mineralization type are complicated and varied. With the comsumption of shallow resources， the deep resources need to be urgently searched in this ore field， which including contact metasomatic skarn tin polymetallic ore and interlayer sulfide tin polymetallic ore. In order to promote the breakthrough of deep prospecting in Gaosong ore field， the wide-field electromagnetic method is applied to this area， and through this method ascertained the distribution of deep geologic body. At the same time， this article comprehensively analysed the metallogenic geological characteristics， and summarized the geological characteristics of different types of ore bodies. Meanwhile， combined with the wide-field apparent resistivity characteristics， the geologic and geophysical model of two main deposit types in Gaosong ore field are established. According to this model， the potential ore bodies in deeper can be effectively prediction， which can provide reference for geophysical exploration in the Gejiu and other similar polymetallic ores in China. |
