毕业论文：激发极化法在找矿中的应用.doc

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AbstractAccordingtothegeologiccharacterofthelead_zincoresareaofYezuinHuidongcountyofSichuanprovinceandthegeologicdatawhichcollectedall-aroundintheworkarea,Itisintroducedadesignthatgoon1:5000defyMiddleGradientInstrumentInducedPolarizationMethodinthispaper.Itisdescribedthegeologicalsituationandphysicalgeographycharacteristic,discussedtheworkingandrequireoftechnologywhichincludedpreferencesandthelaidgeodesic,themethodwhichdealwiththeoriginaldata,theweaveofchart,thefeeintheworkarea,themanageandorganize,theharvestwhichisprospectiveandthetimethatputintheharvest,andsoon.Throughphysicalprospectingdetailedsurvey,itcanlook-overandchecktheimportanceofunusualcharacteristicandthemine.Keyword:InducedPolarizationMethod;MiddleGradientInstrument;polarizability;lead_zincores;inducedpolarizationanomaly目录TOC\o\f\h\zHYPERLINK\l"_Toc136695594"绪论PAGEREF_Toc136695594\h１HYPERLINK\l"_Toc136695598"1工作区地质概况及地球物理特征PAGEREF_Toc136695598\h３HYPERLINK\l"_Toc136695599"1.1自然地理概况PAGEREF_Toc136695599\h３HYPERLINK\l"_Toc136695600"1.2地质概况PAGEREF_Toc136695600\h３HYPERLINK\l"_Toc136695601"1.2.1地层PAGEREF_Toc136695601\h３HYPERLINK\l"_Toc136695602"1.2.2构造PAGEREF_Toc136695602\h６HYPERLINK\l"_Toc136695603"1.2.3岩浆活动PAGEREF_Toc136695603\h７HYPERLINK\l"_Toc136695604"1.2.4矿体及围岩蚀变PAGEREF_Toc136695604\h８HYPERLINK\l"_Toc136695605"1.2.5矿床成因PAGEREF_Toc136695605\h８HYPERLINK\l"_Toc136695606"1.3地球物理特征PAGEREF_Toc136695606\h９HYPERLINK\l"_Toc136695607"2工作方法及技术要求PAGEREF_Toc136695607\h１１HYPERLINK\l"_Toc136695608"2.1主要仪器设备PAGEREF_Toc136695608\h１１HYPERLINK\l"_Toc136695610"2.1.1发射机PAGEREF_Toc136695608\h１１HYPERLINK\l"_Toc136695611"2.1.2接收机PAGEREF_Toc136695608\h１１HYPERLINK\l"_Toc136695609"2.2测
