摘　　要：本文在全面总结以往地质和勘探报告等资料的基础上,重点对赋存于下元古界布伦阔勒群地层中的沉积变质型铁矿进行研究,从成矿地质背景分析入手,以区域成矿学理论和典型矿床剖析为指导,总结成矿规律,在GIS软件平台上对多元化信息进行成矿有利分析,运用证据权重法结合网格单元法的矿产预测方法,对西昆仑塔什库尔干地区沉积变质型铁矿资源进行成矿预测研究。对沉积变质型铁床圈定了A类远景区3处,B类靶区5处,C类远景区2处。Based on a comprehensive summary of previous geological and prospecting reports,this paper focuses on the study of sedimentary metamorphic iron ore in the Bulunkuole Group of the lower Proterozoic Erathem in Xinjiang. It begins with the analysis of the geological background of mineralization and summarizes the metallogenic regularities. On the platform of GIS software,it makes an analysis of diversified information related to mineralization and uses the metallogenic prediction methods of weights of evidence combined with the finite element method to conduct prediction of the metallogenic sedimentary metamorphic iron ore resources in the Taxkorgan area of the West Kunlun. The results include 3 places of A-class,5 places of B-class,and 2places of C-class targets,which would play some rule in mineral exploration of this region in the future.
