摘　　要： 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.
