| 为了研究古风化壳型铝土矿中稀土元素的含量及地球化学特征,探讨稀土元素对古风化壳型铝土矿的成因及成矿环境的指示意义。本文以山西沁源县高家山铝土矿、贵州修文小山坝铝土矿、广西靖西县念寅铝土矿、河南申家沟铝土矿为例,并结合前人的研究成果,认为铝土矿的成矿物质来源可能来自底板碳酸盐岩。根据《矿产资源工业要求手册》风化壳型稀土矿边界品位REO>0.07%,上述四个矿床铝土矿中稀土含量大多达到或超过标准,具有巨大的潜在经济价值。 |
| 英文摘要: |
| In order to study the content and geochemical characteristics of rare earth elements in Paleo-weathered crust-type bauxite, the significance of rare earth elements to the genesis and metallogenic environment of Paleo-weathered crust-type bauxite is discussed. This paper takes Shanxi County of Qinyuan Gaojiashan xiaoshanba bauxite bauxite, Guizhou, Guangxi Jingxi County read Yin bauxite, Henan Shen Jia Gou bauxite as example and combined with previous research results, that the ore-forming material sources of bauxite from bottom of carbonate rocks. According to the Manual of Industrial Requirements for Mineral Resources, the rare earth content of bauxite in the four deposits studied in this paper mostly meets or exceeds the comprehensive utilization standard, which has great potential economic value. |
