湖南省主要稀有稀土金属矿床特征

CHARACTERS OF MAIN RARE METAL AND RE DEPOSITS IN HUNAN PROVINCE

湖南省主要有铌、钽、铷、铯、锂、铍、锆等稀有金属及稀土金属矿床。矿床类型以岩浆晚期分异交代型、气成热液型、伟晶岩型、风化壳型和砂矿型为主。稀有稀土金属矿床在空间分布与成因上，与燕山期花岗岩体密切相关，往往具有水平分带和垂向分带规律。

There are mainly Nb, Ta, Rb, Cs, Li, Be, Zr etc. rare metals and RE deposits in Hunan province. The types of deposits basically are differential metasomatism in the later magma, pneumatolytic hydrothermal process, pegmatite process, residual deposits and placer deposits. The distribution of rare metals and RE in space and origin correlated with granite of Yanshan period with horizontal and vertical zonal rules.
