摘 要: 本文以大量实际资料为基础,对粤东某一花岗岩风化壳稀土矿床的地质地球化学特征作了描述。原岩中稀土元素(REE)的含量对矿床的形成是一个必不可少的条件,风化、淋滤使REE迁移,粘土吸附使REE保留并富集,REE在矿床中的分布具有顶、底贫矿,中间富矿的特征。 The thesis is based on a good deal of practical data. It shows the geological and geochemical characteristics of a REE deposit in granitic weathered crust in the eastern part of Guangdong Province. Forming deposit depends on REE content in mother rocks. Weathering, drenching and permeating make REE remove. The clay minerals remain and enrich the REEs by abosorbing them. The distribution of REE has following features in the deposit; poor in the top and bottom, rich in the median.
