| 中文摘要: |
| 本文以大功率激电方法在新疆金岭金属矿勘查为例,金岭矿床的铜锌矿体受凝灰岩层位控制,以黄铁绢英岩化为特征,显示低阻高极化的地球物理特征。而金矿体受断裂构造控制,呈局部富集,以硅化为特征,具有相对高阻高极化特征。为解决金岭深度找矿问题,采用大功率激电中梯和激电测深进行勘探,发现多处高极化异常,其中IP2-1低阻高极化异常,综合分析用激电剖平面和测深断面异常特征,查明矿(化)体赋存位置、分布规模等,进一步明确找矿范围。 |
| 英文摘要: |
| This paper adopts the exploration for Jinling polymetallic desposit in xinjiang as an example. The Cu-Zn ore body of the Jinling deposit is controlled by tuff horizon, characterized by yellow iron shale lithology with geophys- ical characteristics of low-resistance and high-polarization. While the Au orebody is controlled by fault structure and locally enriched, with quartz alteration and characterized by geophysical signature of high resistivity and high polarization. In order to solve the problem about how to search the deep orebodies of the copper-gold mine of Jinling.,application of the methods of High-power induced polarization intermediate gradient and IP souding found several anomalies of high-polarization, one of which named IP2-1 was low-resistivity, and high-polarization. Meanwhile,the ore features in IP plane for both IP intermediate gradient and IP sounding methods are summarized,these features are critical for identifying prospecting area and locating the occurrence position of ore bodies. |
