摘要

随着地电化学测量技术向“轻便化”方向的不断发展,中小比例尺地电化学测量已成为可能。笔者在内蒙古风成砂浅覆盖洛恪顿热液型铅锌多金属矿区约40 km²范围内开展了1:5万地电化学测量与土壤测量效果对比试验,结果表明:①地电化学测量可圈定与已知矿体元素组合相同的Pb-Zn-Ag-As-Bi-Cd等多元素综合异常,且异常位置与已知矿(化)体空间分布范围较一致;②与土壤测量结果相比,地电化学异常范围、衬度及连续性均远优于土壤测量,土壤测量异常仅在小山头残积土出露区呈点状分布;③在试验区西北部风成砂浅覆盖区发现多元素组合地电化学测量异常,根据此异常部署开展了1:1万激电中梯扫面及钻探验证工作,在540余m深处发现6 m厚富Ag、Cu矿体,实现找矿突破。以上试验结果表明,在风成砂浅覆盖区开展1:50 000地电化学测量能有效圈定找矿靶区,可在今后工作中加以推广应用。

Abstract：

With the electro-geochemical survey technology becoming more and more "portable", it is possible to conduct electro-geochemical survey of small or medium scales. In this paper, an effect comparison test of electro-geochemicalsurvey and soil survey at the scale of 1:50,000 was carried out within 40 km² of the hydrothermal type lead-zinc polymetallic ore district in the aeolian sand shallow covered area of Luokedun, Inner Mongolia. The results are as follows: ①Electro-geochemical survey can delineate comprehensive anomalies of Pb-Zn-Ag-As-Bi-Cd, which have the same composition as the known orebodies. The locations of the anomalies are consistent with the known orebodies/ore spots in spatial distribution. ② Compared with the soil survey results, the results of anomaly range, contrast and continuity from the electro-geochemical survey are more superior in that soil soil survey can only find anomalies of spotted distribution in the outcropping area of the hill residual soil. ③The electro-geochemical survey also finds comprehensive anomalies of multiple elements in the aeolian sand shallow covered area in the northwest of the survey area. Based on these anomalies, the 1:10,000 induced-current middle-gradient survey and drilling verification test was carried out. A 6-meter-thick Ag-Cu rich orebody was discovered at the depth of about 540 meter, which seems to have been a breakthrough in ore prospecting. The above test results show that the electro-geochemical survey at the scale of 1:50,000 can effectively delineate the prospecting targets in the shallow covered area of aeolian sand. The electro-geochemical survey can be popularized and applied in future work.
