摘　　要：太行山中段碎云母矿赋存于晚太古界阜平群湾子组地层之中,矿体与围岩产状一致,含矿率比较稳定,矿床应属于区域变质-混合岩化作用成因。The fragmental mica deposits exist in the layers in Wanzi formation of Archean group in the middle part of Taihang mountain. The occurrence of the ore body is coincident with the occurrence of the country rock. The rate of ore bearing is steadier. The deposit is formed by region metamorphism-migm atization.
