| 摘 要： | 糜棱岩是一种具有丰富地质信息的载体，在理论和实践上都有重要的研究意义。从显微超微构造，岩石固态流变，动力变质成矿，成岩模拟实验，构造地球化学，造山带运行学和同位素年代学等七个方面，较全面的阐述了近20年来糜棱岩岩石学的研究进展情况。并简单列举了一些新成果，诸如浅层次糜棱岩的发现，人工糜棱岩的成岩实验和同位素测年新数据等。同时还指出糜棱岩的微观研究可进一步拓展到壳幔流变学，构造年代学和造成带比较学等这些新的学科研讨上。

| Abstract: | Mylonite bears rich information of geological processes and is of great importance not only in the theoretic study but also in the geological practice. In this paper, the authors will review the progresses of mylonite petrology in the past two decades based on studies of micro ultramicroscopic structure, solid state rheology, mineralization of dynamic metamorphism, modeling experiment of rock formation, tectono geochemistry, orogenic kinematics and isotopic chronology. Some new results of mylonite study are discussed, which include discovery of mylonite in the shallow level, experiment of rock formation for the artificial mylonite and new data of chronological dating, etc.. We also suggest that microscopic research of mylonite could be further extended into the new fields in studies of crust mantle rheology, tectono chronology and the comparative geology of orogenetic belts. Finally, it should be shown that some concerning laws of the physics (such as the Helmholty law) will be cited for the mylonite research in the microscopic scale, thus the dislocation forming rule and the michanism of rock rheology could be completely interpreted. Moreover some results and models (example S C foliation type) are also applied on a delineation deformation research, in particular, the discovery of the mylonite in the shallow level has helped to bring new discussion of the seismic rupturing genesis. The various rich informations in mylonites will be explored out through the parameters determinated by the rock mechanics, tectonophysics, geochemistry and rheology, further the new coupling mechanism of the geological action could be revealed in more detail. |
