稀土元素广泛用于岩浆起源、岩浆演化和岩石学领域，用于矿床成因研究和指导找矿只是近几年来的事。笔者通过对河南蒲塘、毛堂金矿不同类型矿石、岩石稀土元素研究，认为在氧化和热液作用下轻稀土元素淋失，重稀土元素相对富集，ΣLREE／ΣHREE比值和ΣREE降低，热液和表生氧化作用对稀土元素的影响是通过斜长石的形成与分解实现的。研究表明，矿化强度与δEu和ΣLRE／ΣHRE有一定的相关关系，这一关系可作为矿床评价的标志之一。
Rare earth elements are widely used in magmatic origin, magmatic evolution and petrology, for the study of deposit genesis and ore prospecting only in recent years. By studying the different types of ore and rock rare earth elements in Pu Tong and Mao Tang gold deposits in Henan Province, the author thinks that the light rare earth elements are leached under the action of oxidation and hydrothermal fluids, and the heavy rare earth elements are relatively enriched. The ΣLREE / ΣHREE ratio and ΣREE decrease, The effect of liquid and superficial oxidation on rare earth elements is achieved by the formation and decomposition of plagioclase. The results show that mineralization intensity has a certain correlation with δEu and ΣLRE / ΣHRE, and this relationship can be used as one of the indicators of deposit evaluation.
