摘要
文章在介绍革命沟矿床区域地质成矿环境、矿床特征、热液蚀变、元素地球化学、含铀矿物学特征的基础上,分析了成矿物质来源、热液活动及成矿物质迁移途径,论述了硅质脉型铀矿床成矿机制。认为革命沟矿床的形成是地层-岩体-构造-热液活动共同控制的特定时空域内的客观产物,区域含铀建造是成矿的物质基础,成矿热液源自幔汁(HACONS),岩浆及期后热液是铀迁移的载体,铀成矿模式强调了硅质脉后期热液沉淀过程是成矿物质的富集过程。
This paper analyzes the ore-forming material source,hydrothermal activity,migration path of the ore-forming material,and discusses the ore-forming mechanism of siliceous vein-type uranium deposit after introduce the regional geological metallogenic environment,deposit characteristics,hydrothermal alteration,elemental geochemistry and uranium-bearing mineralogy of Geminggou deposit. Geminggou deposit is thought to be the objective product in special time-space domain collectively controlled by strata-rock mass-structure-hydrothermal activities. Namely,the regional uranium-bearing formation is the material basis for mineralization,the ore-forming hydrotherm was derived from the mantle ichor（ HACONS）,while the magma and postmagmatic hydrotherm served as the carrier for uranium migration. The metallogenic model of uranium emphasizes that the precipitation process of later siliceous vein hydrotherm is the concentration process of ore-forming material.
