摘　　要：近年来安徽省围绕大别山中生代侵入岩风化壳型矿床开展了大量地质工作,发现了主簿、石关等一批风化壳型钾长石-稀土、稀土矿床,但矿床中稀土矿浸取率普遍偏低。本文通过主簿矿床成矿母岩、风化壳及黏土矿物特征的分析,探讨风化壳中黏土矿物特征对稀土元素富集的控制作用。In recent years,many geological work focused on the Mesozoic intrusive rock weathered crust deposits in Dabie Mountain,Anhui Province.A number of weathered crust potassic feldspar-rare earth deposits were discovered,such as Zhubu and Shiguan,but the leaching rate of rare earth ore was generally low.This paper discussed the control of the the enrichment of rare earth elements by weathered crust through analyzing the characteristics of the ore-forming parent rock,weathered crust and clay minerals in the Zhubu deposit.
