| 摘 要： | 近期我们对我国不同成因伟晶岩进行了地质地球化学研究［１～３］，证明湖南幕阜山伟晶岩属岩浆分异成因，云南哀牢山伟晶岩属变质深熔成因。本文就两地伟晶岩中绿柱石及海蓝宝石矿物学、形成物理化学条件作对比研究，以探讨不同成因伟晶岩特性。１ 地质背景幕阜山位于江南古陆中段，区内出露中元古界冷家溪群变质岩，岩浆活动强烈，广泛出露燕山期花岗岩岩类。冷家溪群地层强烈褶皱，普遍发生浅—中深变质作用，形成板岩、云母片岩，是幕阜山花岗岩体的主要围岩［４］。含铍花岗伟晶岩在二长花岗岩中广泛分布，部分在冷家溪群变质岩中产出…

| Abstract: | Beryls and aquamarines in Mufushan pegmatite,which resulted from a pegmatitic magmatic differentiation,and in Ailaoshan pegmatite,which owe its origin to metamorphic anatexis,have different characteristics on mineralogy,chemical composition,phase and fluid composition of inclusion.The studies show that not only pegmatitic magma may be formed by differentiation of granitic magma but also independent one may directly be emerged by metamorphic anatexis of sediments. |
