大功率激电在张家口地区石墨矿勘查中的应用

Application of High-power Induced Polarization to Exploration of Graphite Ore in Zhangjiakou

张家口地区位于河北省石墨矿成矿远景重点勘探区,为了圈定石墨矿重点勘探靶区,为后续详查工作提供指导,开展了激发极化法测量工作,并结合地质资料进行了分析解译。通过以上工作圈定了两处有利异常,并推断了与异常相关的两处构造。后续槽探与钻孔资料表明,激发极化法在该区石墨矿勘探中是合理有效的。

Zhangjiakou area is located in the key prospecting area of graphite ore in Hebei province.In order to delineate the key exploration targets of graphite ore and then to guide the follow-up detailed survey,induced polarization surveying work is carried out and the analysis and interpretation are achieved combined with geological data.Two favorable anomalies are delineated and two structures related to them are inferred by the above work.Subsequent trenching and drilling data show that the induced polarization method is reasonable and effective in the exploration of graphite ore in this area.
