江西北武夷某多金属矿区复电阻率法勘查效果

THE EFFECT OF APPLYING COMPLEX RESISTIVITY METHOD TO THE EXPLORATION OF A CERTAIN POLYMETALLIC DEPOSIT IN WUYI,NORTHERN JIANGXI PROVINCE

利用V8仪器在江西北武夷某多金属矿区进行金属矿产勘查,着重分析了矿区0线实施复电阻率(CR)法所获电性参数异常与剖面地电结构特征,结合区内地层分布和成矿条件,充分利用CR资料勾绘出深部矿(化)体的平面投影形态。物探推断成果与钻探结果基本吻合,对后续详查施工起到了积极的指导作用。

Based on a brief description of the geological background of the ore district,his paper mainly analyses electrical anomaly properties and ground electric profile features along No.0 line in the ore district by using the complex resistivity method.The horizontal projection shape of ore（mineralized） bodies in the depth are illustrated by application of data from complex resistivity method in combination with a discussion of stratigraphic and metallogenic conditions.Geophysical interpretation played a guiding role in subsequent detailed exploration and was consistent with the drilling results.The complex resistivity method proves to be a practical and efficient technique.
