中文摘要：

四川某地硫磷铝锶矿中除含主要元素磷、铝、铁、硫、锶、钛外,还含有丰富的稀土元素。利用等离子质谱分析（ICP-AES）、扫描电镜及能谱（SEM-EDX）、电子探针（EMPA）等分析手段查明了硫磷铝锶矿中主要元素及稀土元素分布规律及赋存形式。实验结果表明,77%的磷元素、97%的铝元素及大部分锶及稀土元素都分布于硫磷铝锶石中,黄铁矿中稀土元素富集低,铁、钛元素集中于独立矿物黄铁矿、锐钛矿中。

英文摘要：

A svanbergite ore in Sichuan contains abundant rare earth elements in addition to major elements of phosphorus, alu- minum, iron, sulfur, strontium and titanium. The distribution law and occurrence status of the major elements and the rare earth elements in the svanbergite were studied by ICP-AES, EDX-SEM and EPMA and other means. The experimental results showed that 77% of phosphorus, 97% of aluminum elements and most of strontium and REE elements occur in the svanhergite ore, there are low enrichments of rare earth elements in pyrite and the occur rence of iron and titanium elements are concentrated in independent pyrite and anatase.
