Abundant occurrences of quartz vein within eclogites in the Dabie-Sulu orogen provide us an opportu- nity to study metamorphic fluid flow during subduction and exhumation of continental crust. It is, however, usually ...
TTG gneiss is a common rock to outcrop in the northern part of the Dabie orogen, a few of which are closely associated with eclogites that experienced the Triassic ultra-high pressure metamorphism. Although they were ...
The ultramafic massif at Raobazhai in North Dabie is located in the suture zone between the Yangtze craton and North China craton. The Re-Os isotope compositions of the massif are used to decipher the origin and tecto...

Hualiangting whiteschist in the Dabie Shan ultrahigh-pressure eclogite complex is a specific Mg-Al-rich metamorphic rock. Its protolith was a felsic dyke, which suffered replacement by high-pressure fluids during ec-l...
