摘要
通过对某铀矿床各构造地球化学带的稀土元素特征参数和球粒陨石标准化配分曲线的分析和研究,结果表明此矿床矿石与岩浆岩有着相同的稀土元素特征,铀主要来自于矿区内富铀花岗岩岩体.稀土元素相关的特征值变化表明该矿床在成矿过程中,成矿环境从相对还原环境向相对氧化环境改变,成矿温度逐渐降低.
Analysis and research are based on REE geochemical parameters and chondrite_normalized REE distribution curve of each geochemical and tectonic belt in a uranium de_posit . The results show that magmatite have the same characteristics of REE with ore in this deposit,and the uranium mainly come from the mining area granite which is rich in urani_um. Variation of REE features show that metallogenic environment change from relatively reducing environment to relatively oxidizing conditions and the temperature of mineraliza_tion is decreased gradually in the mineralization.
