| 中文摘要: |
| 通过对西天山二牧场一带1：5万水系沉积物测量工作测试分析的16种元素地球化学分布特征、异常组合进行总结，发现二牧场一带的Au、As、Pb、Zn、Y、Mo、W、Sn等元素与西天山背景相比较富集，而Au、Ni、Co、Cr、Cu相对亏损； R型聚类分析以0.4为界，全区元素可分为四组；在对重要异常进行查证时发现铜矿点2处，铅锌矿点1处，铁矿点1处；对该地区的矿床类型及找矿方向进行了探讨，并圈定2处找矿远景区，提出3种矿床类型：火山热液改造型铜矿、中基性岩类磁铁矿、构造（热液）蚀变型铅锌矿。 |
| 英文摘要: |
| Stream sediment survey at scale 1:50000 was completed in Ermuchang area of the west tianshan mountain and 16 elements are analyzed. Elements of Au、As、Pb、Zn、Y、Mo、W、Sn are relatively more concentrated than the background values of the area, Ni、Co、Cr、Cu relatively depleted. Demarked by 0.4 of R-type cluster analysis value the working area there are 4 element anomly combinations, i.e. Cr-Ni-Co-Cu-Zn、Au-As-Sb、Bi-Pb、Sn-Y-Nb. During check of anomlies aere encountered 2 copper ore occurrences, 1 Pb-Zn ore occurrence and 1 Fe ore occurrence. Ore deposit types and ore prospecting directions are discussed. There are 3 types of ore deposit, i.e. the volcaic hydrothermal reworked copper deposit, the intermediate-basic rock-related magnetite ore deposit and tectonic (hydrothermal alteration type of Pb-Zn ore deposit then two targets are put forward. |
