| 摘 要： | 对与辉锑矿共生萤石的稀土元素地球化学特征研究表明，所有萤石均具有Ce负异常，其稀土配分模式存在3种类型：Eu弱亏损型、Eu正常型、Eu富集型。从成矿早期至晚期，萤石的稀土配分从Eu弱亏损型向富集型演化，稀土总量逐渐降低，并由中稀土富集向轻稀土富集演化。成矿流体可能主要属于盆地流体，具有十分低的稀土总量，在成矿作用过程中，成矿流体由早期的还原条件转化为晚期的氮化条件，由中稀土富集向轻稀土富集演化。 |

| Abstract: | Based on the study of REE geochemistry of fluorite coexisted with antimony, negative Ce anomaly and three types of the REE distribution patterns such as negative, normal and positive Eu anomaly for fluorite were recognized. Total REE content decreased gradually and the REE evolved from enriched MREE to enriched LREE as the REE distribution pattern evolved from depleted Eu to enriched Eu from early to final mineralisation stage. The ore fluid was from basin fluid and changed from reduced condition to oxidized condition during mineralization. |
| Keywords: | fluorite fluid REE geochemistry |
