| 摘 要： | 本文对大别山榴辉岩流体包裹体进行了研究。包裹体成分以ＮａＣｌ－Ｈ２Ｏ、Ｈ２Ｏ、ＮａＣｌ－ＣＯ２－Ｈ２Ｏ为主，是在退变质的角闪岩相和绿片岩相条件下捕获的。从变质高峰期至退变质晚期，包裹体成分演化由氧化向还原转化。熔融包裹体的发现，说明榴辉岩在形成过程中伴随局部深熔作用。通过流体包裹体研究，对大别山榴辉岩抬升过程ｐ－Ｔ－ｔ轨迹进行了探讨，认为是一等温降压过程。

| Abstract: | This paper deals with fluid inclusions in cclogite from the Dabieshan region, Anhui. The fluidinclusions are compositionally predominated by NaCl-H2O, H2O and NaCl-CO2-H2O, which wereentrapped during the amphibolite- and greenschist-facies regressive metamorphism. From, the peakstage of metamorphism to the late stage of regressive metamorphism the composition of fluid inclusions shows an evolution trend from oxidizing to reducing. The discovery of melt inclusions provides with partial anatexis. Fluid inclusion studies have shed much light on the possible uplifting p-T-t path of eclogite in the Dabieshan region-a process of isothermal depressurization. |
