摘　　要：经昆仑区域成矿地质背景、成矿地质环境与成矿标志分析 ,认识到花岗岩、花岗闪长岩内、外接触带受断裂控制的热液脉型矿化特征是明铁盖地区的首选找矿目标。经野外实际调研 ,在花岗闪长岩外接触带找到了罗布盖子沟多金属矿化区。对罗布盖子沟多金属矿化区地质特征、化学分析、野外调查等综合分析 ,形成明铁盖地区 Pb- Zn、Cu、Au矿化综合成矿模式。经过野外验证 ,系统采样测试 ,和 Pb、Zn、Cu、Ag、Au趋势面分析图揭示了矿化强度的空间变化 ;由元素趋势面图分析和研究区内矿化特征综合分析建立了明铁盖地区的已知矿产成矿模式 。By analysis of regional geological background,mentallogenic geological environment and mineralization mark in Kunlun region,it is recognized that the contact zone between granite and granodiorite which controlled by fault zone heat mineralization is the first mineral survey location in Mingtiegai region The multi mental metallogenic province was found at the outer contact zone of granodiorite after site investigation The Pb,Zn,Cu Au multi mental granodiorite pattern was set up according to geological characteristics,chemical analysis and site investigation The mineralization degree and the change tendency in space was understood by site experiment,samples analysis and Pb,Zn,Cu,Au distribution tendency analysis The mentallogenic pattern of Mingtiegai region was established according to the element distribution tendency and mineralization characteristic analysis; and the results have a great guideline function to the minerals investigation
