对西藏自治区昌都县昂青矿区地质特征及成矿原因分析

Geological characteristics and metallogenic cause analysis of ang Qing mining area in Changdu County of Tibet Autonomous Region

昂青矿区位于西藏自治区昌都地区昌都县妥坝乡,地处昌都县三河一江地区(昂曲、扎曲、色曲、澜沧江),属中深切割区。工作区最高海拔5078m,最低4412m,相对高差660多m,地表多为基岩裸露或被坡积、残积、冰积砾石、碎石流所覆盖,植被较少,山麓局部地带,零星分布有草甸及灌木。海拔在4500m以下的地区多为灌木和草甸所覆盖。本文对昂青矿区地质特征及矿床成因进行了研究探讨。

Ang green mining area is located in Changdu County of Changdu Tuo BA Xiang Tibet autonomous region, is located in Changdu County Sanhe river area（ang Qu, Zhaqu, color song, Lan Cangjiang）, is a deep cutting area. The highest elevation 5078 m, minimum 4412 m and relative elevation difference of more than 660 m were found in the working area. The ground surface was mostly exposed to bedrock or covered by slope, residual, ice gravel and gravel flow, with less vegetation, and there were scattered meadows and shrubs scattered in the foothills. Most of the areas below 4500 m are covered by shrubs and meadows. In this paper, the geological characteristics and ore genesis of ang Qing mining area are discussed.
