英文摘要Multiple high-pressure (HP) metamorphic veins and their host ultrahigh-pressure (UHP) eclogites in the Hualiangting area (Dabie terrane, China) were investigated to constrain the provenance of vein-forming fluids, element transfer during UHP fluid-rock interaction, and "closed-system" vein crystallization in a deep subduction zone. The HP veins consist of significantly different mineral assemblages and can be classified as omphacite-epidote (Omp-Ep), epidote-quartz (Ep-Qz), and kyanite-epidote-quartz (Ky-Ep-Qz) veins from the vein-eclogite boundary to the vein interior. Towards the veins, the abundances of coesite-enclosing epidote, kyanite, and quartz in the eclogite systematically decrease, indicating an intensive fluid-rock interaction between the eclogite and vein-forming fluid. Mass-balance calculations indicate that the interaction resulted in strong depletion of Sr and Pb (up to -80% to -90%); moderate depletion of U (up to -80%), Th (up to -50%), light rare earth elements (LREEs) (up to 40-60%), and transition metal elements (TMEs) (Cr, V, Sc, Co, and Ni) (up to -40%); and low depletion of heavy rare earth elements (HREEs) (<-25%) in the eclogites near the vein. The mass losses of these trace elements gradually increase towards the vein and are largest in the eclogite nearest the vein.
