摘要

荧石是在 Maoniuping REE 存款的主要脉矿物之一,四川省,中国。有不同颜色的荧石发生在各种各样的矿体以内不仅,而且在矿石地的墙岩石中。把地球化学基于 REE,矿石地里的荧石能作为 LREE 富有、 LREE 扁平、弄空 LREE 的类型被分类。三从一样的热水的液体来源在不同阶段形成的荧石打字,与在在最近的阶段的相对早的阶段,在中间的 LREE 扁平的荧石,和弄空 LREE 的荧石形成的 LREE 富有的荧石。证据的各种各样的线证明荧石的 REE 内容的变化不显示出关系到颜色。Maoniuping REE 存款的矿化作用空间地被联系,有 carbonatite 正长岩岩浆酌和形成矿石的液体的速度集合主要从碳酸岩被导出,正长岩融化。

Fluorite with different colors occurs not only within various orebodies, but also in wallrocks of the orefield. Based on REE geochemistry, fluorite in the orefieid can be classified as the LREE-rich, LREE-flat and LREE-depleted types. The three types of fluorite formed at different stages from the same hydrothermal fluid source, with the LREE-rich fluorite forming at the relatively early stage, the LREE-flat fluorite in the middle, and the LREE-depleted fluorite at the latest stage. Various lines of evidence demonstrate that the variation of the REE contents of fluorite shows no relation to the color. The mineralization of the Maoniuping REE deposit is associated spatially and temporally with carbonatite-syenite magmatism and the ore-forming fluids are mainly derived from carbonatite and syenite melts.
