| 摘 要： | 以Ｐ－Ｔ－ｔ轨迹为手段，有助于探讨变质作用随大地构造演化或变迁而动态演化的特点，本文主要讨论了古元古代普遍出现的低压高温变质作用、高压高温变质作用及其Ｐ－Ｔ－ｔ轨迹，而且讨论了高压低温变质作用在古元古代很少出现的原因。在此基础上，综述了以上各类变质作用的各种可能的构造成因模式。

| Abstract: | By using P-T-t path,it is helpful to discuss the characteristics of dynamic evolution of metamorphism associated with the geotectonic evolution or with the migration.This paper describes mainly general low-pressure pyrometamorphism,high-pressure pyrometamorphism and P-T-t path as well as the cause that is of rare occurrence in Paleoproterozoic high-pressure epimetamorphism.On the basis of it,the structural -genetic models from the above-mentioned metamorphism are comprehensively discussed. |
