1、毕业论文题目新疆白杨河铀－铍矿田成矿规律及预测英文题目XinjiangPoplarRiveruraniumberylliumorefieldmetallogenicregularityandpredictionof学生姓名学号专业资源勘查工程系别资源勘查工程系指导教师职称讲师二零一二年六月摘要雪米斯坦火山岩带是新疆规模最大的铀－稀有金属成矿带之一，成矿带长约120km，由白杨河铀－铍矿田及雪米斯坦工区、七一工区、十月工区、阿尔肯特矿点和一批异常点组成，区域上主干大断裂控制了矿床、矿点、矿化点的分布，次级断裂及岩体界面、熔岩层面是具体矿化的赋存部位，成矿特征
2、具一定的相似性，而其中的白杨河铀－铍矿田是铀－铍矿化最集中的地区，研究其成矿规律，对区域找矿具一定的借鉴意义。白杨河矿田主要铀、铍矿体受次火山岩体顶、底界面控制，呈似层状，与铀矿化有关的蚀变主要为赤铁矿化、紫黑色萤石化和锰矿化，与铍矿化有关的蚀变主要为萤石化、碳酸盐化和硅化，成矿期至少经历了铀矿化、铀－铍矿化、铍矿化三个阶段。通过成矿规律研究，认为白杨河铀－铍矿田寻找800m以上深部矿体的主攻地区为四号工地东部，白杨河以东地区找矿要从地表受裂隙控制的次要矿体入手，重点寻找深部受熔岩控制的层状矿体。关键字：雪米斯坦火山岩带；白杨河铀－铍矿田；成矿预测ABST
