THE crystalline-fluid melt inclusions in aquamarines in pegmatites from Mufushan (Hunan Prov.) andAilaoshan (Yunnan Prov.) have been studied. The research shows that there are obvious differences inthe chemical composition of the inclusions in the aquamarines, which is of great importance for studyingthe forming mechanism and origin of pegmatites. 1 General geology of pegmatites Mufushan is situated in the middle sector of the Jiangnan Ancient Land. The granitic pegmatitesmainly outcrop in granite mass of late Yanshanian (105-145 Ma) which was intruded in middle sector ofthe middle Proterozoic strata. Part of the pegmatites occur in the contact zone of the granite and the metamorphic rocks. The pegmatite veins may be divided into four types, all of them were originated from mag-
