| 中文摘要: |
| 研究区位于华北地台北缘赤峰-朝阳金矿化集中区，成矿地质条件优越。自上世纪四十年代在该区发现矿化露头以来，一直没有找到主矿体。为了解决该区的找矿问题，在充分研究工作区的地质、地球物理特征前提下，采用了大功率激发极化中梯装置扫面和EH4连续电导率测深相结合的方法进行勘查，达到了良好的找矿效果。激电中梯扫面结果表明，矿致异常表现为中高电阻率、中高充电率异常，异常连续性好，呈近南北向展布，延长超过850m，未封闭；EH4连续电导率测量结果表明，异常向深部连续、清晰，异常产状近于直立，宽度约100m，延深超过600m。上述异常均与已知矿体具有良好的对应性，显示了矿区具有良好的深部找矿潜力。 |

| The work area located in the Chifeng-Chaoyang gold concentration region on the northern margin of North China block has good mineralize condition. Since the day when mineralization outcrop be found in 1940s, there is less production. According to the geologic and geophysical characteristics in the study area，we chose appropriate methods and technique which including high-power intermediate gradient IP and the Stratagem EH4 system, obtaining a relative ideal result for mine prospecting. The results of the intermediate gradient IP measure indicates anomaly which caused by mineralization body puts up mid-high apparent resistance rate and mid-high apparent charging rate. And the anomaly extends to a depth of more than 800m nearly along longitude direction, continuous and not close down. The results of the Stratagem EH4 system show the anomaly extends to a width of about 100m and nearly vertically more 600m, consecutively and clearly. The anomaly has good corresponding with foregone ore spot, and reveals that there is a good metallogenic prospect in the depth. |
