DISCUSSION ON THE METAMORPHIC STAGE AND P-T-t PATH OF LIAOHE GROUP

  • 摘要: 有些文献将辽河群中不同变质级别的矿物组合看成不同阶段的矿物组合,实际上它们是异地异时异相,是空间上的并列关系,不是时间上的更迭关系,更不应该将空间上并列的不同变质级别的矿物组合温压条件的连线当成P-T-t轨迹.这种连线是野外变质梯度,它与P-T-t轨迹大角度相交.把野外变质梯度当成变质作用P-T-t轨迹来讨论辽河群变质作用演化是不合适的.
    Abstract: In some literatures, the mineral assemblages of different metamorphic grades of Liaohe Group are regarded as the mineral assemblages of different stages. Actually, they are the results of different sites, times and phases. They just coexist spatially, but not temporally. The pressure-temperature condition curves of mineral associations of different metamorphic grades should not be served as the P-T-t paths. In fact, this kind of curves is field metamorphic gradient, which intersects the P-T-t path with large angle. Therefore it is inappropriate to discuss the metamorphism evolution of Liaohe Group with field metamorphic gradient instead of P-T-t path.
