| 摘 要： | 本文用现代的固体表面分析方法和连续选择性提取法对冕宁黑色风化物中稀土元素的赋存状态进行研究因。在可交换离子相，易还原相，水成相和矿物结晶相四种稀土存在的形式中，易还原相和水成相是自然界矿物中新的稀 存状态。特性吸附是产生这两种新相的内在原因。

| Abstract: | The black weathered mineral in Mianning orebed has been studied by modern analytical means of solid surface and the method of sequential selective extraction. The results show that there are four kinds of combining states of the REE in the black weathered mineral. They belong to four different geochemical phases:exchangeable ionic phase respectively, reducible phase, aqueous mineral phase and crystalline mineral phase. The REE reducible phase and aqueous mineral phase are two new combining state of REE in natural mineral. Formation of new phases is caused by the characteristic adsorption. |
