摘要
本文主要研究离子吸附型稀土矿床的地质特征、成矿地质条件及矿床类型.该类矿床经历了内生和外生两个成矿作用阶段.据成矿特点将成矿类型划为三类.稀土矿化富集具一定的规律性,配分类型齐全,各稀土元素配分之间存在明显的相关关系.华南具有广阔的找矿远景.
This study deals extensively with metallogenetic conditions and genetic classification and geological characteristics of weathering crust ion adsorption rare earth elements deposits. This type of REE deposits is suffered endogenetic and epigenetic metallization. They are divided genetically into 3 types based on meallogenetic characteristics: (1) granite-weathering crust type; (2) migmatite-weathering crust type (3) volcanic - subvolcanic weathering crust type. Deposits show some regularities on REE minoralizalization. There are five types of REE distribution clearly correlated. There is a splendid prospecting area in south China.
