山西交口‐汾西地区王润‐西崖底铝土矿床是山西省地质调查院近年来发现的大型铝土矿床。本文通过对王润‐西崖底铝土矿的研究，分析铝土矿样品的稀土元素含量特征，研究铝土矿床稀土元素分布特征以及与铝土矿床的关系，探讨稀土元素对于本区铝土矿成因和环境的指示意义。研究表明：该区铝土矿体的ΣREE总量较大，轻稀土元素相对富集，具有明显的Eu负异常；利用稀土元素图解大致反映出铝土矿成矿物质的来源于上地壳，底板碳酸盐岩为铝土矿床源岩，铝土矿形成于海相或海陆过渡相弱氧化环境。铝土矿床ΣREE与Al2 O3含量存在正相关性。

The bauxite deposits in Shanxi Wangrun‐Xiyadi region ,which was found by Shanxi Institute of Geological Survey in recent years ,it is a large‐size deposits .Through the research of bauxite deposits , analyze the content of the rare‐earth elements in samples of deposits ,and research the relationship between the characteristics of rare‐earth elements and the deposits ,discuss the significance of the genesis and environment of bauxite deposits from the rare‐earth elements .This study shows that the ΣREE of bauxite deposits is large in this region ,light REE relative enriched ,with Eu negative abnormality ;using the diagram of REE ,we know that the metallogenic source material comes from the upper crust .The carbonate rock of bottom plates is source bed .The bauxite deposits occur on the weak oxidation environment of Marine or Transitional facies ,there was positive correlation between the ΣREE and Al2 O3 in deposits .
