时间域激发极化法在内蒙古镶黄旗某锌钨多金属矿的应用

寻找隐伏矿产是当今地质工作者面临的一项重要任务。隐伏矿产埋藏深度大,矿床地质特征复杂,因此寻找隐伏矿产不仅需要地质成矿理论的指导,也需要依靠地球物理手段求取深部信息。本文介绍了利用时间域激发极化法在内蒙古镶黄旗某锌钨多金属矿区找矿的效果。通过激电中梯扫面和测深工作,发现了高极化率异常与锌钨多金属矿体具有良好的空间对应关系,大致圈定了与成矿有关的金属硫化物富集体范围。结合地质资料与钻探验证,证实了矿体的存在。

Application of the time-domain induced polarization method to the Zn-W polymetallic deposit in Xianghuang Qi, Inner Mongolia

Prospecting concealed deposits is one of significant tasks of geologists.Such deposits are usually buried deeply with complex geological features.Thus prospecting these deposits depends on the guidance of metallogenic theories as well as the deep deposit information derived from geophysical exploration.This paper presents the application of time-domain induced polarization method to a Zn-W polymetallic deposit in Xianghuang Banner,Inner Mongolia.The intermediate gradient induced polarization measurement and electrical sounding by the induced polarization method have found high polarization anomalies corresponding to the distributions of Zn-W polymetallic deposits,delineating the rough distribution of metallic sulfide related with mineralization.The results verify the existence of ore bodies in combination with geological and drilling data.
