| 摘 要： | 通过对辽河群岩石中主要变质矿物的观察和研究，以岩石的变形历史作为变质结晶作用的相对时标，确定了矿物生长的时序特征及其演化过程。发现变质与变形既是有密切联系的又是各自独立的地质作用，辽河期的变形作用存在明显的３个变形幕，而辽河期的变质作用是个连续的完整的过程，无明显的热波动。变质作用高峰和变形作用高峰存在时间差。

| Abstract: | Based on the studies on the major metamorphic minerals from Liaohe Group,the chrono-genesis characteristics and evolution process of the minerals growth are ascertained while thedeformation history of the rocks is regarded as the relative timemark of metamorphic crystal-lization. Then the metamorphism and deformation are discovered to be closely related and al-so independent.The deformation occuring in Liaohe period has undergone obvious 3episodes,but the metamorphism in Liaohe period has undergone a complete and continousprocess without obvious thermal fluctuation,and there is time difference between the peaksof metamorphism and deformatijon. |
