地电化学提取技术在青藏高原干旱荒漠区的参数对比研究及找矿预测——以拉陵高里河西地区为例

Comparative study on the parameters of geo-electrochemical extraction technology and prospecting prediction in the dry desert region,Qinghai-Tibet plateau:A case study on Lalinggaolihexi region

通过对拉陵高里河西地区多金属矿床地质特征的研究,结合其已有的地质、物化探等工作,开展了找矿新技术——地电化学提取技术的找矿试验研究。为了研究该技术方法在拉陵高里河西地区的找矿应用效果,首先在矿区内进行了地电化学工作参数对比试验,从而得到了适合拉陵高里河西地区的最佳技术参数,之后利用该套技术参数在找矿未知区进行了地电化学提取,最终圈定了5处地电化学异常找矿预测靶区,建议重点对BQ4号甲类异常靶区进行查证工作,有望实现找矿上的突破。

On the basis of studying geological characteristics of polymetallic ore deposits in the Lalinggaolihexi region, in combi- nation with the known geological, geophysical and geochemical information etc., the experimental study of new prospecting technology, namely, geo-electrochemical extraction technique was carried out.In order to study the application effect of geo-electrochemical extrac- tion technique in the Lalinggaolihexi region, first the comparision experiment was carried out to obtain the best technical parameters. Then using the obtianed technical parameters, geo-electrochemical extraction was carried out in unknown area. Finally the five prospec- ting target areas were outlined. It is recommended that the anomalous verification should focus on BQ4 target area in order to achive the prospecting discovery.
