Discovery of the eclogite and its petrography in the Northern Dabie Mountain

Eclogite from the Northern Dabie Mountain is a new finding by the authors. These eclogites in foliated perdotite are enveloped by banded gneiss and oc cur in the mafic-ultramafic rock belt. They are mainly composed of omphacit e, garnet, diopside, orthopyroxene, amphibole, plagioclase and magnetite, a nd a small amount of rutile, spinel, olivin and corundum, The mineral assoc iation of peak metamorphism of the eclogite is omphacite+garnet+rutile. The existence of eclogite in the Northern Dabie Mountain implies that there wa s an eclogitic metamorphism prior to the granulitic facies one in the mafic -ultramafic rock belt.
