摘　　要：The compositions of daughter mineral of melt inclusion in beryls, which are from pegmatites of Keketuhai in Xinjiang and Mufushan in Hunan, have been analyzed by electronic probe. Ten kinds of mineral, such as beryl, zinc-spinel, mica, quartz, magnetite, etc., which consist of different mineral associations have been identified. The zinc-spinel existing in two dif-The compositions of daughter mineral of melt inclusion in beryls, which are from pegmatite of Keketuhai in Xinjiang and Mufushan in Hunan, have been analyzed by electronic probe. Ten kinds of mineral, such as beryl, zinc-spinel, mica, quartz, magnetite, etc., which consist of different mineral associations have been identified. The zinc-spinel existing in two different forms was first discovered in the melt inclusion in China and abroad. This study provides that there exist the local magmatic differentiation and the immiscibility and heterogeneity of magma. It is very useful for the current research of magmatic rocks, pyrolite, meteorolite.
