| 中文摘要: |
| 卡拉塔格矿集区处于荒漠戈壁景观区,区内发育有大面积盐碱层。低电阻率背景与高接地电阻降低了传统电法的勘探深度和对异常的分辨能力,影响了其在深部找矿方面的应用效果。广域电磁法采用大功率、全域视电阻率测量,理论上可增加勘探深度,测量由于不受远区条件限制,较传统的CSAMT测量效率也大大提高。为了探索卡拉塔格矿集区电法深部探测问题,2019年在矿区将广域电磁法与CSAMT、激电测深等方法进行了应用对比,结果吻合度较高,探测深度有了很大的突破,在以往资料的基础上发现了更多的深部找矿线索。 |
| 英文摘要: |
| The Kalatge Ore Concentration Area is located in gobi desert landscape where massive saline formation is distributed. The background of low resistivity and high grounding resistance reduced the exploration depth and anomaly resolution of the traditional electrical method, and affect its application in deep prospecting. The wide-fied electromagnetic method(WFEM)uses high-power and apparent resistivity measurement in all-area, which can theoretically increase exploration depth. Compared with traditional CSAMT, the measurement efficiency of WFEM is greatly improved because it is not limited by remote conditions. In order to explore the deep detection problem of the electric method in Karatage, the WFEM method was applied to compare with CSAMT, IP sounding and other methods in the mining area in 2019. The results proved to be reliable while the prospecting depth was promoted. More deep prospecting clues had been found depending on previous information. |
