【摘要】 由于稀土元素在各种地质作用中具有一定的活动性，正确考虑稀土元素的地球化学活动性是运用稀土元素解释地质问题的基础。本文系统地研究了湘中锡矿山锑矿田各矿床中蚀变硅化岩及其原岩、矿石及矿物的稀土元素地球化学特征，指出稀土元素在硅化蚀变和矿化过程中的确有一定的活动性，并讨论了制约稀土元素活动性的主要因素。更多还原

【Abstract】 REE is very useful in interpreting some geological problems. However as the fact of the mobility of REE during some geological processes, it is necessary to evaluate the REE mobility degree. In this paper, the REE geochemical characteristics of minerals, ores, altered rocks and related unaltered rocks in Xikuangshan antimony orefield have been described. Studies indicate that there was some mobility of REE during the silicification and the mineralization. The factors controlling the mobility of REE are discussed.更多还原
