The widely distributed Archaean rocks of Wulashan Group in the area mainly belong to granulite facies. The rocks of Wulashan Group consist of granulite,granulitite and amphibole-plagioclase-gneiss in lower unit.The rocks of middle unit are composed of biotite-amphibole-plagioclase-gneiss, interca- lated with granulite, amphibolite and magnetite-quartzite. The rocks of upper unit consist of biotite ( or amphibole)-plagioclase-gneiss, quartzite, cordierite- bearing-sillimanite-garnet-K-feldspar-gneiss and marble intercalated with ma- gnetite-quartzite. Energy dispersive X-ray spectrometer and wet, chemical analysis were carried out on orthopyroxene, clinopyroxene, garnet, amphibole, biotite and plagioclase from the rocks. It appeared that chemical equilibrium was approximated. Metamorphic crystallization temperatures,obtained by the Wood-Banno, Nehru-Wyllie and Lindslay-Dixen two-pyroxene geothermome- ter method fall in the range 768-857`G.Metamorphic temperatures obtained by the Perchuk's amphibole-orthopyroxene, biotite-clinopyroxene geothermo- meters diagrams range from 700-835 C.Metamorphic temperatures by Saxe- nays garnet-biotite geothermometer diagram range from 770-820℃ with a mean of 795℃. Pressure calculated by Wood garnet-orthopyroxene geobaro- meter method is 9.9×108Pa. Pressure calculated by Newton-Perkins and Wells garnet-orthopyroxene-plagioclase geobarometer methods range from 8.3 to 10.1 with a mean of 9.2 × 108Pa. *Institute of Geology, Academia Sinica.
