| 摘 要： | EH4连续电导率剖面仪是利用人工电磁场源与天然电磁场源测量大地电阻率的一种频率域和时间域相结合的大地电磁测深系统,兼有单点测深和剖面测量的双重功能。文章以广东河台金矿、安徽桃冲铁矿EH4电磁测深应用为例,在分析区域地质情况、综合前人研究成果的基础上,详细进行了测量剖面成果的解译。测量结果表明,EH4电磁测深系统在成矿预测和控矿构造解译方面的应用效果好,对深部矿体形态、延深及控矿构造的展布反演清晰,对2个矿床进一步的找矿工作意义重大,也进一步证实了EH4电磁测深技术在地质勘查方面的应用前景广阔。 |

| Abstract: | Stratagem EH4 system is a magnetotelluric sounding system combined with time domain and frequency domain by means of measurement of earth resistivity with artificial electromagnetic field source and natural electromagnetic field source. Not only it can sound depth of a single point but also measures profile. Taking Hetai gold deposit and Taochong iron deposit as examples, the profile measurement is interpreted with good result. Morpholgy and extension to depth of the ore body and distribution of ore-control structure are clearly displayed by reversion and is of significant for further ore prospecting in future. |
| Keywords: | Stratagem EH4 system ore-controlling structure ore prediction |
