Some Recent Advances in Metamorphic Geology
变质地质学的某些进展

The research of metamorphic facies geology has experienced two stages in its development over 160 years, viz. the static and dynamic approaches. Before 1960's, it, exemplified as depth zones, was dominated by the static approach. From the beginning of 1960's, the studies of metamorphism has commenced to turn to the dynamic approach through the work of Miyashira who proposed the concept of metamorphic facies series which, however, was still kept in the static framework by that it did not indicate the change of the geotherm with the metamorphic process. Since 1970's, the research of metamorphic geology has been characterized as dynamic approach by the progresses as follows: (1) a world wide mapping of metamorphic belts in small scale has been performed to evaluate the spatial and temporal relations of types of metamorphism in terms of facies series and facies groups within continental crust; (2) by virtue of the development of laboratory experiment, microanalytical techniques and the theory of thermodynamics, it can be precise to calculate the P T conditions of mtamorphic rocks, but to model the most of the natural metamorphic reactions in laboratory; (3) through the detailed analysis of microtextures of metamorphic rocks, the relationship between metamorphic recrystallization and deformation in a metamorphic process can be visualized; (4) on the principles of heat transfer theory and modern thermodynamics, it is probable to determine the metamorphic PTt path by inverse and forward modellings and to evaluate the dynamic process of metamorphism and the linkage of the thermal regime with the involved tectonism.
