REE Zoning Characteristics of Yuechengling Pluton and Its Significance to the Genesis of Rock Mass
Based on the project"Investigation and Evaluation of Rare and Rare Metal Mineral Resources in the Yuechen-gling Area of Hunan Province",more than 500 rock and soil samples in the area were statistically analyzed through data com-parison,graphical analysis,and other methods.The content characteristics and distribution patterns of rare earth elements in different lithofacies zones and vertical soil zones were analyzed,and the indicative significance of rare earth elements on the genesis of the Yuechengling rock mass was discussed.The research results indicate that there are significant differences in the content of rare earth elements in various lithofacies zones of the Yuechengling rock mass,and the zoning is obvious;Rare earth elements are more abundant in soil compared to rocks;The distribution curve of rare earth elements in this area leans to the right;Light rare earth elements are relatively enriched compared to heavy;The Eu medium negative anomaly is common;The characteristics of rare earth elements indicate that the rock mass has the characteristics of remelted granite.
