河北省石墨矿产地质特征与找矿概述

Geological Characteristics and Prospecting of Graphite Minerals in Hebei Province

为了进一步解决我国矿产资源稀缺问题,河北省国土资源局和地质勘探局将石墨矿产作为下一阶段主要的找矿目标。近年来,使用物探法在寻找石墨矿产工作中取得了一定进展。为了进一步提高找矿效率,针对石墨找矿过程中存在的问题,采用激电中梯法和自然电位法对具有高极化低电阻属性的石墨矿进行探测,并取得非常良好的效果。通过具体案例,对这2种物理探测法在石墨找矿中的应用进行分析。经论证,物探方法在石墨找矿工作中取得了良好效果,可以作为未来石墨找矿工作中的主要探测方法。

In order to further solve the problem of scarcity of mineral resources in my country,the Bureau of Land and Resources and the Bureau of Geological Exploration have made graphite minerals the main prospecting target in the next stage.In recent years,some progress has been made in the search for graphite minerals using geophysical methods.In order to further improve the prospecting efficiency,aiming at the problems existing in the process of graphite prospecting,the geophysical prospecting methods of in⁃duced polarization gradient method and natural potential method are used to detect the graphite ore with high polarization and low resistance properties,and very good results are achieved.Through specific cases,the application of these two physical detection methods in graphite prospecting is analyzed.It is proved that geophysical prospecting method has achieved good results in graphite prospecting work and can be used as the main detection method in future graphite prospecting work.
