云南省永平卓潘碱性岩体中稀土元素赋存状态研究

Study on The Occurrence of Rare Earth Elements in Zhuopan Alkaline Rock Body in Yongping,Yunnan Province

永平过碱性杂岩体因有利的成矿条件,形成了风化壳型磷灰石稀土(砂)矿床。稀土元素的主要赋存形式有离子吸附型和类质同像两种类型,重砂矿物主要为磷灰石、磁铁矿等,还见少量独居石。磷灰石作为主要的赋矿矿物,稀土氧化物含量较高。

The Yongping super-alkaline complex has formed weathering crust type apatite rare earth(sand)deposit because of favorable ore-forming conditions.The main occurrence forms of rare earth elements are ion adsorption type and ISOMORPHISM type.The heavy placer minerals are mainly apatite,magnetite and a few monazite.As the main ore-bearing mineral,apatite has high content of rare earth oxides.
