摘 要本文根据四川省会东县野租铅锌矿区的地质特征，在全面收集区内已有地质资料的基础上，设计了 1：5000 中间梯度装置激发极化测量方法。简单介绍了该工区地质概况、地球物理特征、激发极化法的基本原理，讨论了其参数选择和测线布置等野外工作方法及技术要求、质量评述和数据处理方法与图件编制等方面的内容，详细地论述了数据处理和对异常区的解释，分别绘制了视极化率和视电阻率的等值线异常图。其目的是通过物探普查工作，寻找矿区的激电异常并对其分析解释，从而为地质找矿提供钻孔具体分布位置。关键字:激发极化法；中间梯度装置；极化率；铅锌矿；激电异常 AbstractAccording to the geologic character of the lead_zinc ores area of Yezu in Huidong county of Sichuan province and the geologic data which collected all-around in the work area, It is introduced a design that go on 1:5000 defy Middle Gradient Instrument Induced Polarization Method in this paper. It is described the geological situation and physical geography characteristic, discussed the working and require of technology which included preferences and the laid geodesic, the method which deal with the original data, the weave of chart, the fee in the work area, the manage and organize, the harvest which is prospective and the time that put in the harvest, and so on. Through physical prospecting detailed survey, it can look-over and check the importance of unusual characteristic and the mine.Key word: Induced Polarization Method; Middle Gradient Instrument; polarizability; lead_zinc ores; induced polarization anomaly 目 录绪 论.....................................................................................................................................１1 工作区地质概况及地球物理特征...................................................................................３1.1 自然地理概况..........................................................................................................３1.2...
