　　[摘 要]自然电场法是一种圈定含墨岩系范围和寻找石墨露头较简单和方便的物探方法[1]，尤其对地表露头或浅部异常，作用较好[2]。本文通过实例，采用自然电场法，研究区内石墨矿的分布情况，对区内石墨矿潜力进行综合评价，圈定出一处重点成矿靶区，对该地区后期槽探和钻探工作提供了重要的实际意义，阐明了该方法在石墨矿普查应用中的可行性。

　　[Abstract]Natural electric field method is a simple and conventient geophysical method for delineating graphite bearing strata and finding graphite outcrops[1]，especially having a perfect effect on the outcrop and shallow part of the surface[2]. in this paper，through a case ，adopt the natural electric field method to synthetically study the distribution in workplace， to comprehensively evaluate the potential of graphite ore in the area. Finally a key metallogenic target area is delineated，provides important and practical significance for late trenching and drilling work，expounds the feasibility of the method in the survey and application of graphite ore.
