摘　　要：皖中张八岭蓝片岩带含硬玉和石英组合，位于扬子地块北缘，是我国蓝片岩带压力最高的地区。以矿物共生组合为基础，将蓝片岩带划分为５个矿物带：黑硬绿泥石—白云母带；红帘石—白云母带；蓝闪石—青铝闪石带；阳起石带；白云母带。The Zhangbaling blueschist belt in central Anhui contains the jadeite and quartz assemblage.Situated on the northern margin of the Yangtze block,it is a highest pressure belt among the blueschist belts in China.On the basis of the mineral assemblages,the belt may be divided into five mineral zones:the stilpnomelane muscovite zone,piemontite muscovite zone,glaucophane crossite zone,actinote zone and muscovite zone.The authors discuss the mechanism of the uplift of the blueschist to the surface possibly due to underplating.
