英文摘要	Lanshantou eelogites in the southeastern Shandong province are located in the middle part of the Sulu ultra-high-pressure metamorphic terrane, Eastern China. The area is dominated by foliated granitic gneisses. Eclogites occur as blocks in granitic gneisses. Fluid inclusions in coesite-bearing eclogites and eclogite-facies quartz veins at Lanshantou in the Sulu terrane have preserved remnants of peak metamorphic and exhumation fluids. Four types of fluid inclusions have been distinguished: (1) N-2 +/- CO2 inclusion, (2) H2O-CO2 inclusions, (3) hypersaline H2O inclusion, and (4) low salinity H2O inclusions. N-2-rich fluids were introduced during or just after peak metamorphism. CO2-H2O and hypersaline fluids were trapped in high pressure eclogite-facies re-crystallization stage. Low salinity H2O fluids were related with the latest evolutionary stage of ultrahigh pressure exhumation (amphibolite-facies retrogression). The possibility of deciphering the relative chronology of the fluid pulses can provide fluid evolution history during exhumation of ultra-high-pressure metamorphic rocks.
