摘要
含铍条纹岩是碱性富氟花岗岩浆演化到晚期,因不混溶作用产生的含矿热流体对碳酸盐岩或夕卡岩强烈淋滤而成的含铍富氟蚀变体.和夕卡岩相比,矿物组合不同,形成时间较晚,介质偏酸性,应属云英岩.
The Be-bearing perthitic rock, being a fluor rich and Be-bearing alteration product, is formed by
carbonate rock or skarn which is strongly leached by ore-bearing hydrothermal fluid produced by unmixing process at the late evolution stage of fluor rich alkali-granite. In comparison with skarn. it
should belong to greisen because it is formed at a later stage, has a different mineral assemblage and exists in a more acidic medium
