Stream Sediment Geochemical Characteristics and Prospecting in Diqia Area of Qinghai Province

Publish Date: 25 December 2015

摘要: 对青海迪恰地区1/5万水系沉积物测量结果进行初步分析,发现迪恰区以Au、Ag、Sb元素异常为主,伴有As、Hg、Bi、Cd、Cu、Sn等多元素组合异常,其形态主要受NW和近东西向断裂构造控制.对元素分布特征,相关性分析,因子分析,异常展布特征进行了探讨,认为Au、Ag、Sb为区内具有一定找矿潜力的元素,进而优选出滑日以金找矿远景区,龙特金锑多金属找矿远景区,鲁干隆哇银砷多金属找矿远景区.

Abstract: Based on 1/50 000 stream sediment survey in the Diqia area of Qinghai Province, we find an anomaly combination of multiple elements dominated by Au、Ag、Sb and accompanied by As、Hg、Bi、Cd、Cu、Sn. It is sug-gested that the anomaly is controlled by a number of NW-EW trending fracture zones. The study included the characteristics of element distribution, cluster analysis, factor analysis and anomaly distribution. The result re-veals that the Diqia area might be a prospective area for Au、Ag、Sb. Three ore prospecting areas are chose:the Huariyi area with Au anomaly, the Longte area with Au-Sb multiple metal anomaly, and the Luganlongwa area with Ag-As multiple metal anomaly.
