    MINERAL ZONING OF THE ZHANGBALING BLUESCHIST BELT IN ANHUI PROVINCE

    • 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。阐述了蓝片岩可能在板底垫托作用下抬升至地表的机制

       

      Abstract: 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.
