| 中文摘要: |
| 为了寻找厚覆盖层深部找铁多金属矿的有效综合物探方法,在鄂尔多斯台坳的河东断凹与桑汾地堑系的临汾断陷交界处勘查中深部铁多金属矿应用高精度磁法、可控源音频大地电磁测深法(CSAMT)、重力测量和天然场音频大地电磁测深法(AMT)、大地电磁测深和频谱激电测深等物探方法的组合研究。研究表明高精度磁测和天然场音频大地电磁测深法为该区域中深部寻找铁多金属矿床最为适用的物探组合方法。 |

| In search of effective comprehensive geophysical prospecting method for finding the iron polymetallic deposit under the deep covering layer,this paper conducted research on the application of various of geophysical prospecting methods including high precision magnetic method, the controlled source audio-frequency magnetotelluric sounding (CSAMT), gravity survey and natural audio magnetotelluric sounding (AMT), magnetotelluric sounding and spectrum IP sounding in the exploration activities for deep iron-poly metallic research at the junction of the Hedong fault sag of Ordos basin and Linfen rift of Sangfen graben system. It has been found that the effective methods for the search of iron polymetallic deposits in deep covering layer are high precision magnetic survey and natural audio magnetotelluric sounding method, so this paper plays a guide role in selecting a suitable geophysical method for the regional mid-deep detection. |
