摘要
内蒙渣尔泰群变质岩中白云母的电子探针分析表明是多硅白云母,白云母的成分特征表明变质岩的形成温度为260℃～350℃、压力5GPa～8GPa。白云母的b_0值为9.003～9.033,属中压变质相系。白云母b_0值的差异则与不同的构造部位有关。
The electron microprobe analysis of the muscovites from the metamorphic rocks Of the Zhaertai Group, Inner Mongolia shows that, they are phengites. The component of muscovite shows that the metamorphic temerature of the rocks ranges from about 260℃—350℃ and the pressure from 5GPa—8GPa. The b_0 value of the muscovites of the metamorphic rocks ranges from about 9.003—9.033, belonging to metamorphic facies series of medium pressure type. The b_0 value of muscovite is related to the structure location.
