Abstract:Petrologic investigations of eclogites from the Luotian dome in the North Dabie complex zone (NDZ) suggest that the eclogites underwent ultrahigh-pressure (UHP) metamorphism and recorded a complex multistage evolution history. As a result, they exhibit multiple decompression textures and rare preservation of former UHP metamorphic record. The eclogites are characterized by high-T metamorphism and multiple symplectites that formed by granulite- and amphibolite-facies metamorphism during decompression. Main UHP metamorphic evidences are coesite pseudomorphs, indicated by the occurrence of radial cracks around quartz inclusions and of polycrystalline quartz inclusions in garnet, and relic coesite in zircon. The newly established Ti-in-zircon and Zr-in-rutile thermometers provide a possibility to estimate the peak and post-peak temperatures of the eclogites in the region and the results indicate that the eclogites experienced a long-lived and extended high-T metamorphic evolution from HT/UHP eclogite-facies to UHT/HP granulite-facies stages characterized by near-isothermal decompression during the initial stages of exhumation. UHT metamorphic conditions were inferred by applying Cpx-Opx geothermometry to the hypersthene lamellae and the host clinopyroxene. Therefore, the studied eclogites experienced UHP metamorphism and multiple decompressions during high-T exhumation. This may be one of the major reasons why the coesite and related UHP records are rarely preserved in the NDZ. | |||
