| 摘 要： | 风化壳型稀土矿层的发现在河南省尚属首次,其w（ΣREO）平均值为0.12%,已达到现行规范中轻稀土矿床的一般工业指标。该稀土矿层（体）与铝土矿密切共生,组分中有高铈,中镧、钕,低铕、钇的特点,初步认为该矿层属古风化壳吸附型轻稀土矿床。本次发现对以后在河南省本溪组中稀土成矿研究和找矿工作具有一定指导意义,并随着该稀土矿层的开发,将共同推动河南省铝土矿资源全面综合利用。 |

| Abstract: | It is the first time to discover palaeo-weathering crust type REE deposit in Henan province. The average content of Y.REO is 0.12%, reaching the present industrial standard of LREE deposit. The deposit is closely associated with bauxite and characterized by high Ce, moderate La and Nd, low Eu and Y content. It is considered to be the palaeo-weathering crust absorption-type LREE deposit . The discovery is of significance to future REE ore-forming study and mineral reconnaissance in Bengxi Group, and will promote the comprehensive utilization of bauxite deposit in Henan province,along with the exploitation of REE deposit. |
