激发极化法在山东牟平某金矿区的应用

Application of Induced Polarization Method of a Gold Mine of Muping,Shandong Province

为查明山东牟平某金矿区矿化体的分布特征以及深部发育富集情况,进一步优选找矿靶区,开展了激发极化法测量工作。通过激电中梯扫面圈定了4处激电异常,在这些异常重点部位开展了激电测深工作。通过结合区内地质资料、岩(矿)石特征及实地踏勘情况对取得的测深剖面进行了分析解译,推断本次激电测量工作圈定的异常主要反映黄铁矿化石英脉和黄铁矿化蚀变岩,深部发育富集情况较好,这些异常发育区域为矿区内有利的金成矿部位,是后续详查工作和找矿重点区域。此次激发极化法在该金矿区的应用取得了较好的找矿效果。

In order to find out the mineralization distribution characteristics and the deep development of a gold deposit located in Muping of Shandong Province and to definite an optimal prospecting target area,Induced Polarization （IP） method is applied in measuring work.Depth sounding of induced polarization method is carried out in the mining area where four induced polarization anomalies are defined through the middle gradient area measurement.Combining with the geological data in the area,rock ore characteristics and field reconnaissance,the sounding profiles are analyzed.It can be inferred that the delineation of four induced polarization abnormalities are caused by pyrite quartz vein and pyrite mineralization alteration rock, and the mineralize development well in deep, they are favorable gold metallogenic area in this area.The IP survey helps to identify follow-up survey work and find the key area of the mine, and good results have been achieved in the application of this gold mine.
