A metamorphism in green-schist facies conditions. The epidote crystals is subhedral to eu- hedral, with high Al2O3 26-30 % and low Fe2O3 5–8% contents. It is predominantly zoisite Xcz = 0.46 to 0.72 and subordinate epidote Xep =0.27-0.53 in composition, with typical compositional zoning due to variable substitution of Fe3+ and Al3+ on octahedral sites and sector-zoning. The epidote is suggested to have a possible igneous origin, and to be crystallised from a wet H2O>5 wt % magma under low fO2 and intermediate pres- sure conditions during initial stage crystallisation on the basis of its petrographical and mineralogical characteristics
