摘　　要：湖南香花岭锡铍多金属矿床的含Li、Be条纹岩和有关交代岩,在世界上独一无二,产于燕山期(155~154 Ma)富氟花岗岩接触带及岩体的围岩捕掳体中,围岩为中上泥盆统灰岩和白云质灰岩。按矿物共生组合特征,条纹岩可大致分为铁锂云母条纹岩、氟硼镁石条纹岩、金绿宝石条纹岩、粒硅镁石-磁铁矿条纹岩和金云母-绿泥石条纹岩5类。与条纹岩有关的交代岩生成稍晚,可大致分为香花石交代岩、金云母交代岩、粒硅镁石交代岩、符山石-磁铁矿交代岩、金云母-绿泥石交代岩和韭闪石交代岩6类。文章对条纹岩和有关交代岩的生成地质背景、矿物共生组合和岩石地球化学特征进行了探讨。The Li,Be-bearing ribbon rocks and related metasomatites in the Xianghualing tin-beryllium-polymetallic orefield are unique in the world. They occur in the F-rich granite contact zones and zenolith of wall rocks. The wall rocks are limestone and dolomitic limestone of Middle-Upper Devonian period. According to mineral paragenesis,the ribbon rocks may be divided into five types, i. e., zinnwaldite ribbon rock, fluoborite ribbon rock, chrysoberyl ribbon rock, chondrodite-magnetite ribbon rock and phlogopite-chlorite ribbon rock. The related metasomatites were formed late and may be divided into six types, i. e., Xianghualite metasomatite, phlogopite metasomatite, chondrodite metasomatite, vesuvianite-magnetite metasomatite, phlogopite-chlorite metasomatite, and paragarite metasomatite. The geological setting, mineral paragenesis, and geochemistry of the ribbon rocks and related metasomatites are discussed in this paper.
