| 朱溪特大型钨铜矿床的发现，使大游山地区W-Cu多金属的成矿潜力受到广泛的关注。本文依据1：5万水系沉积物测量成果，探讨大游山地区成矿元素含量、分布、组合以及综合异常等特征。结果显示，朱溪地区与长源坞地区异常强度高，规模大，元素套合好，朱溪地区为W-Cu多金属找矿远景区，长源坞地区为W-Bi多金属找矿远景区。 |

| Abstract: |
| Dayoushan area has become a focus of potential ore-finding areas since the discovery of Zhuxi tungsten-copper deposit, a super-large-scale tungsten-copper deposit in the region. Based on the geochemical survey data of stream sediments at the scale of 1:50000, this paper discusses the content, distribution, assemblage, and comprehensive anomalies of ore-forming elements in the Dayushan area. The results show that the Zhuxi area and Changyuanwu area are potential for ore-finding of tungsten and copper, and both areas are with large scale intensive geochemical anomalies which are related to ore-forming of tungsten and copper. We believe that Zhuxi area is a prospective area for W and Cu and Changyuanwu area is a prospective area for W and Bi. |
