摘　　要：浙江八面山萤石矿床有4个成矿期次,第2次为蚀变作用,其它三次为热液作用。第1次成矿作用形成的矿石有7大类型,色深(黑灰、深灰)、普遍含碳泥质、金属矿物和粘土矿物出现概率较高。第2次成矿作用形成的矿石有两种,色浅(绿灰、灰白)、符山石和斜长石含量较高、不含金属矿物和碳泥质。第3次成矿作用仅形成了黑灰、黑色铁质含量高的纹层状矿石。第4次成矿作用形成的矿石有3大类、10亚类,某些亚类进一步分为若干种,颜色鲜艳多彩、碳质出现概率高、金属矿物出现概率低、不含粘土矿物。第1和4次形成的矿石品位较高。矿石类型共计13大类,以第1次形成的黑-黑灰色中细粒块状矿石为主。四次成矿作用,物质来源不尽相同。Bamianshan fluorite deposits of Zhejiang province were formed by four metallogenic periods, the second period is alteration and the other three ones belong to hydrothermal activity. There are seven types of dark （black gray and dark gray） ores with carbon pelitic formed in the first period, most are metallic and clay minerals. Two types of light ores were formed in the second period, most are green-gray and hoariness, with high content of idocrase and plagioclase but no metallic minerals and anthrinoid pelitic. There are only ore type of ore formed in the third period that is black gray and black ferruginous lamellated ore, but three types and ten sub-types of ores formed in the fourth period, with vivid colors and more carbon minerals but less metallic minerals and no cray minerals.
