摘要
文章阐述了岑溪糯垌稀土矿床地质特征及其矿石特征、矿石有用组分含量及变化规律、矿石化学成分、矿石浸取率及稀土元素配分类型等,认为岑溪糯垌稀土矿床属黑云钾长(二长)花岗岩风化壳离子吸附型稀土矿床,稀土元素配分类型为低铕富镧钕轻稀土型,矿层主要赋存于花岗岩全风化层中。
This paper elaborates on geological characteristics,ore characteristics,content of useful component in ore and its variation regularity,ore chemical composition,ore extraction rate and types of REE partitio-ning.The author believes that Nuodong rare earth deposit of Cenxi is a kind of biotite moyite (adamellite) weathering crust ion adsorption type rare earth deposit,and REE partitioning is light rare earth element with low europium and rich lanthanum and neodymium.The ores are mainly occurs in fully weathered layer of the granite.
