摘要
西藏察隅县那阿钨矿是发育于冈底斯基底岩系中的矽卡岩型白钨矿床。本文从矿区地层、构造、岩浆岩方面分析了矿区的成矿地质背景,总结了矿床地质特征,根据实际勘查工作归纳了矿区的成矿模式,包括三个阶段:第一阶段为区域变质作用形成矿源层阶段,第二阶段是热液交代富集成矿阶段,第三阶段是构造改造阶段。
The Na'a scheelite deposit in Zayu, Tibet, is Skarn type deposit developed in the basement rocks of Gangdise. This paper analyzes the metallogenic geological background of the mining area from the aspects of strata, structure and magmatic rock, summarizes the geological characteristics and the metallogenic model of the deposit according to the actual survey work, this model includs three stages: regional metamorphism formed the source stage; hydrothermal metasomatism enrichment stage and Tectonic transformation stage.
