| 摘要: |
| 通过对雪莎地区开展1∶5万水系沉积物测量、样品采集和数据综合处理，圈定了Au、As、Sb、Hg、Ag等16种元素的单元素异常和35处综合异常。依据元素地化特征、元素相关性分析以及异常评序查证结果，划分出4个找矿远景区。重点分析了界米拉综合异常，结合查证结果，初步探讨了测区的找矿方向，为该区今后地质找矿部署提供了依据。 |

| Abstract: |
| By carrying out 1:50,000 stream sediment survey, we have located geochemical anomalies of 16 elements such as Au, As, Sb, Hg and Ag in Xuesha area, Tibet, respectively. At the same time, We have fixed 35 multi-elements geochemical anomalies in the studied area. Based on correlations of elements and geological verification in the field, we suggest that four metallogenetic prospective areas are potential for ore deposits of gold and antimony in Xuesha area. |
