物探方法在赣东北岩山钨锡矿调查区中的应用

Application of Geophysical Prospecting Method in Yanshan Tungsten-Tin Mine Investigation Area in Northeast Jiangxi Province

研究区地质工作程度较低,利用高精度磁测、激电中梯剖面测量两种物探方法,结合已有的地质分析,推测区内花岗岩体向东南部侵入,区内存在两处明显的激电异常,均与地下含钨破碎带有关。经钻探验证与物探推断的花岗岩体情况相吻合,为下步工作提供了找矿方向。

The geological work in the study area is relatively low.Using high-precision magnetic survey and IP radder,combined with the existing geological analysis,inferring the granite intruded into the southeastern part of the study area.Two obvious IP anomalies are all related to the underground tungsten-bearing fracture zone.The drilling verification coincides with the situation of the granite body inferred by geophysical prospecting,which provides the prospecting direction for the next work.
