东昆仑地区二道沟石英脉型白钨矿矿床地质特征及找矿前景分析

Geological Characteristics of Erdaogou Quartz-vein Type Scheelite Deposit in East kunlun Area and Its Prospecting Prospect

二道沟钨矿床是目前青海省内发现的规模较大前景较好的石英脉型白钨矿矿床,通过进一步工作,有望成为大型乃至超大型白钨矿床。对二道沟白钨矿成矿地质背景、矿体特征及围岩蚀变进行了分析探讨,结合勘探工作成果初步认为该矿床成因类型为石英脉型白钨矿,并初步分析了二道沟地区该类型矿床的找矿前景,认为该区是寻找与岩体有关的石英脉型钨矿的有利地段。对于区内及邻区白钨矿的找矿工作有一定的参考价值。

province. about the Erdaogou tungsten deposit is a quartz-vein type scheelite deposit with great prospects in Qinghai It is expected to become large and super large scheelite deposit by the further work. This paper discusses mineralization geological background, including orebody characteristics and wall rock alteration of Erdaogouscheelite deposit. Combining with the exploration results, it suggest that the genetic type is quartz-vein type scheelite deposit. We also analyzed the prospecting prospect in this area to consider its favorite area for quartzvein type tungsten deposit. The above research results will have certain reference value for the scheelite prospecting work in this region and its adjacent area.
