    Indicator of Fluorite Sr and Nd Isotope to Mantle-Derived Ore-Forming Fluids in Maoniuping REE Deposit, Sichuan Province, China

    • 摘要: 萤石是四川牦牛坪稀土矿床主要的脉石矿物之一, 其形成贯穿了整个稀土成矿过程, 因此同位素的研究对探讨萤石和稀土成矿流体的来源具有重要的价值.矿区6件萤石样品的Sr、Nd同位素组成没有明显差异.结合围岩(碳酸岩-正长岩, 花岗岩)同位素组成特征研究表明, 不同颜色、来自不同矿石类型、具有不同REE类型的萤石为同源产物, 稀土成矿流体来源于富集地幔, 与区内碳酸岩-正长岩岩浆活动密切相关.
