摘要
为研究豫西地区铝土矿床中伴生稀土元素的品位及地球化学特征,讨论稀土元素在本地区铝土矿中的赋存状态及价值.本文以豫西地区铝土矿床中五门沟铝土矿、关底沃铝土矿、黄漫铝土矿为研究对象,运用基本分析和光谱半定量分析方法开展分析,以及δEu负异常研究,发现关底沃、五门沟和黄漫δEu平均值分别为0.63、0.54、0.57,∑REE平均含量分别为732.91×10-6、648.24×10-6、540.86×10-6,认为稀土元素以分散状态赋存于水硬铝石和高岭土等含铝矿物中,推测豫西地区的铝土矿中蕴藏着大量的轻稀土资源,勘查开发潜力巨大,具有很高的开发价值.
Abstract
The research focuses on evaluating the quality and investigating the geochemical traits of intercon-nected rare earth elements located within the bauxite of western Henan Province.Further,the symbolic importance of these elements in the context of bauxite formation and the generation of a mineral-rich environment in the same region is also explored.This article takes the Wumengou,Guandiwo,and Huangman Bauxites in the western Henan province as the research objects.Through basic analysis and semi quantitative spectral analysis methods,the study suggests that the formation of bauxite is closely related to the carbonate rocks on the floor.The rare earth content in some areas of bauxite has exceeded the ore boundary grade,which has enormous development value.
