The unusually low Ö180 values of -10.3 to -6.8%0 are found in mineral separates from an ec10gite pod (containing quartz-schist bands) in the Su-Lu terrane, East China. These are the lightest oxygen isotope compositions so far reported for metarnorphic rocks in the world. Oxygen isotope equilibrium has been approached among the minerals within both ec10gite and quartz-schist. This not only yields the concordant isotope temperatures of 655 to 765°C, but also indicates that the rocks have… 
Hydrogen and oxygen isotope compositions of eclogites from the Dabie Mountains and geodynamic implications
Heterogeneous δ18O values as low as - 2.6‰ to+7.0% are observed for ultrahigh pressure eclogites from the Dabie Mountains in East China. Oxygen isotope equilibrium has been approached between the
Low δ18O eclogites from the Kokchetav massif, northern Kazakhstan
Oxygen isotopic compositions of silicates in eclogites and whiteschists from the Kokchetav massif were analyzed by whole‐grain CO2‐laser fluorination methods. Systematic analyses yield extremely low
Carbon Isotope Anomaly in Marbles Associated With Eclogites From the Dabie Mountains in China
High δ13C values, up to +5.7‰ (PDB), were measured in marbles associated with ultrahigh‐pressure eclogites in the Dabie Mountains, East China. Such a carbon isotope anomaly is interpreted to
Stable Isotope Geochemistry of Ultrahigh-Pressure Rocks
Stable isotope geochemistry gives unequivocal evidence that the protoliths of ultrahigh-pressure (UHP) metamorphic rocks were at Earth’s surface prior to continental collision and subduction.
