The Dabie Shan ultrahigh-pressure (UHP) metamorphic terraneis located in the eastern part of the eastwest-strikingQinlingDabie orogenic belt in China. A major mylonitizedcontact zone of 200300 m width divides Dabie Shan intothe South Dabie Terrane (SDT) and the North Dabie Complex (NDC).Combined investigation of major and trace element geochemistry,fluid inclusions, and oxygen and hydrogen isotopes constrainsthe fluid history during the metamorphic evolution of the twometamorphic belts, which differ in their fluid and metamorphicevolution. Fluid inclusions in rocks from the SDT are mainlyaqueous with varying salinities, whereas those from the NDCare dominated by CO2. Low 相似文献
