| 摘 要： | 自七十年代后期大功率短导线激电法推广以来,激发极化法的使用迈进了小比例尺普查阶段,成了区域找矿评价的重要方法之一。近几年来,区域激电普查成果不仅在成矿带的找矿远景评价上得到了广泛应用,而且在基础地质研究中的效果也日益显著。无论在地质构造填图上,还是在开展间接找矿方面都收到了不同程度的成效。

ROLE OF HIGH-POWER INDUCED POLARIZATION INGEOLOGICAL MAPPING AND INDIRECT EXPLORA-TION OVER DAHEISHAN AREA IN JILIN |
| |
| Abstract: | This paper is adapted from the results of 1:25,000 high power IPreconnaissance over Daheishan district, in central Jilin Province. Based on the macroscopic characteristics of the polarization field with special reference to the geological data available, fairly good results were achieved in geological mapping, e. g., in defining fracturel, features and stratigraphical conditions as well as in discriminating strata, and intrusives etc. The general geological picture constructed on IPinformation furnishes a better insight into the ore-controlling geology, helps to locate the favorable areas of mineralization, thus reduceing the target area for prospecting, and, according to the actual geological conditions, sifting out the best anomalies for follow-ups so as to provide prospective areas for further exploration. |
