Quartz-eclogite blocks were discovered in Shuanghe area of the Dabie Mountains, which belongs to theso-called hot eclogite terrain. The peak metamorphic assemblage of the eclogites is garnet + omphacite +phengite + kyanite + rutile + quartz. Their P-T conditions are estimated as p=2.0 GPa and T=700℃ byusing g arn et- omph acite-ph en gi ie b arc m eter and garn et- omph ac lie thermometer. Tecton ic ally, thecontrast in peak metamorphic temperatures is more significant. Therefore, the quaftz-eclogite inShuanghe could also be considered as “hot” eclogite, although it experienced no UHP metamorphism.
