目录学号：HEBEIUNITEDUNIVERSITY毕业论文GRADUATETHESIS论文题目：冀东马城铁矿矿床地质特征分析学生姓名：xxx专业班级：xxxxx学院：矿业工程学院指导教师：xxxx副教授2013年06月17日摘要ⅠⅡ摘要在实验和现场调查的基础上，对马城铁矿的地层、构造、混合岩化作用、矿体特征、矿石矿物等方面进行分析研究，总结马城铁矿的矿床地质特征。查阅资料表明，马城铁矿地层为双层结构，基岩为太古界单塔子群白庙子组变质岩，上覆第四系。矿体形态复杂，矿石类型主要为磁铁石英岩，矿体由单层或多层铁矿层组成，呈层状、似层状、大透镜状。浅部多夹石，具有分枝自然尖灭、膨胀收缩现象。镜下观察得出其变质岩主要为黑云变粒岩和黑云角闪变粒岩夹磁铁石英岩。通过与司家营、石人沟、水厂铁矿等典型沉积变质型铁矿床的对比，得出马城铁矿成矿年代相对较新，混合岩化作用强烈，并且破坏矿体的完整性、连续性；变质程度较高的结论。关键词马城铁矿；沉积变质；矿床地质特征AbstractAbstractBasedontheexperimentandfieldsurvey,foranalysingtheMachengironorestrata,migmatization,orebodycharacteristicsandoreminerals,summarizingMacheng’sgeologicalcharacteristicsofdeposit.AccordingtoinformationindicatesthattheMachengformationfordouble-layerstructureofironore,MasuburbanminingQuaternarycoveralargearea,Archeanbedrockofasingletowersubgroupbaimiaozigroupmetamorphicrocks.Theorebodyshapeiscomplex,theoretypesaremainlymagnetitequartzite.Ironorebyasingleormulti-layer,layered,layered,largelenticular.Moreshallowwithstone,withapinchofnaturalbranches,expansionandcontractionphenomena.Lithologyismainlybiotiteandbiotitegranuliteamphiboliteleptynitefoldermagnetitequartzitethroughmicroscope.BycomparisonwiththeSijiaying,Shirengou,ShuichangIronMineandothertypicalsedimentary-metamorphismirondeposit,theMachengironoreintherelativelynew,migmatizationstrongly,anddestroytheorebody’sintegrityandcontinuity,alsothedegreeofmetamorphismishigher.KeywordsMachengironore;Sedimentary-metamorphism;Geologicalcharacteristicsofdeposit目录目录ⅢⅣ目录TOC\o"1-3"\h\uHYPERLINK\l_Toc1691摘要PAGEREF_Toc1691IHYPERLINK\l_Toc22538AbstractPAGEREF_Toc22538IIHYPERLINK\l_Toc30517第1章综述PAGEREF_Toc305171HYPERLINK\l_Toc148481.1沉积变质型铁矿床概述PAGEREF_Toc148481HYPERLINK\l_Toc165571.2冀东沉积变质铁矿概述PAGEREF_Toc165572HYPERLINK\l_Toc285861.3马城矿区的勘查历史及现状PAGEREF_Toc285863HYPERLINK\l_Toc187081.4研究思路和研究方法PAGEREF_Toc187084HYPERLINK\l_Toc152041.4.1研究思路PAGEREF_Toc152044HYPERLINK\l_Toc50501.4.2研究方法PAGER
