英文摘要	The garnet–bearing mica–quartz schist of the Sumdo high pressure metamorphic beltfrom the Lhasa block is mainly composed of garnet,muscovite,albite,quartz and minor chlorite,rutile and sphene.Garnet displays obvious zonation where Xpy[=Mg/(Mg+Fe+Mn+Ca)]increases from the core to the mantle,and then decreases in the rim;Xsps[=Mn/(Mg+Fe+Mn+Ca)]declines gradually from the core to mantle,suggesting that garnet composition; The garnet–bearing mica–quartz schist of the Sumdo high pressure metamorphic beltfrom the Lhasa block is mainly composed of garnet,muscovite,albite,quartz and minor chlorite,rutile and sphene.Garnet displays obvious zonation where Xpy[=Mg/(Mg+Fe+Mn+Ca)]increases from the core to the mantle,and then decreases in the rim;Xsps[=Mn/(Mg+Fe+Mn+Ca)]declines gradually from the core to mantle,suggesting that garnet composition; 大陆构造与动力学国家重点实验室; 2; Vol.89
