| [摘 要]野外采用高精度磁法与双频激电法相结合的方式对蒙古国中戈壁省某铁-锌多金属矿区进行地球物理勘查评价，圈定出多个低磁、高视幅频率、低视电阻率异常区，经工程验证该异常由多个铁-锌金属矿体引起，矿体赋存于花岗岩与大理岩接触交代所形成的矽卡岩带内，矿床成因类型为接触交代矽卡岩型，矿床规模为中型。该矿区研究结果表明，高精度磁法与双频激电法的联合应用，可以快速圈定深部铁锌多金属矿化异常体，并为后期探矿工程部署提供指示，是寻找同类型矿床的有效方法之一。 |

| Abstract: This paper utilized a combination of high-precision magnetic and dual-frequency IP methods to carry out a geophysical evaluation on an iron-zinc polymetallic deposit in Middle Gobi Province of Mongolia，and delineated several anomaly areas with low magnetic, high apparent amplitude frequency and low apparent resistivity. Engineering verification suggests that these anomalies are caused by several iron-zinc metal orebodies. These orebodies occur in the skarn zone formed by the contact metasomatism between granite and marble. Genetically, this deposit belongs to a contact metasomatic skarn type, and its scale is of medium size. The results show that a combination of high-precision magnetic and dual-frequency IP methods is effective for seeking the same type of these deposits, which helps to quickly delineate the deep iron-zinc polymetallic mineralization anomalous bodies and provide guidance for later deployment of prospecting. |
