摘　　要：本文总结了我国中南地区与花岗岩有关的离子吸附型稀土矿床的风化壳结构、矿物组合特征和成矿机理等研究情况。基于中南地区——湖南、湖北、广西、广东和海南五省区的地质背景对该区与花岗岩有关的稀土矿床成矿条件进行了分析,采用已知矿床(化)点或矿集区、花岗岩出露条件、地形因素结合气候等因素作为预测依据,对中南地区与花岗岩有关的离子吸附型稀土矿床成矿区带进行了预测,划分出5个Ⅰ级成矿区带、6个Ⅱ级成矿区带和9个Ⅲ级成矿区带。The structure of weathering granite crust,mineral assemblages and ore-forming mechanism related with ion-adsorption type REE deposit are summarized in the central-south China. Based on the geological background,the metallogenic conditions of these deposits in Hunan,Hubei,Guangdong,Guangxi and Hainan provinces are analyzed. The concentration area of known deposits（ points）,granite outcropping conditions,topography and climatic factors are collected that are favorable to mineralization. It is found that there are 5 places ofⅠ metallogenic belt,6 places of Ⅱ metallogenic belt and 9 places of Ⅲ metallogenic belt in central-south China area.
