摘要
通过对洞中拉铅锌矿床稀土元素的研究,判定矿石与地层(灰岩)有着相似的稀土元素特征,同时矿石与侵入岩也有着密切的关系。矽卡岩全岩的稀土元素分布模式表现出承袭了侵入岩的分布模式。稀土元素相关的特征值变化表明,在成矿过程中,成矿温度逐渐降低,成矿环境从相对还原的条件向相对氧化的条件改变。
Based on the study of REE geochemistry of Dongzhongla Pb-Zn deposit in Tibet,REE in ores and strata(limestone) has the same REE geochemistry characters,and ores are closely related with magmatic rocks.REE distributive mode of skarn ores inherits the distributive mode of intrusive rocks.Variation of REE characteristic value shows that during the metallogenic process,the mineralizing temperature was decreasing and mineralizing conditions changed from relative reducing environment to relative oxidation environment.
