A set of carbonate mylonite was distributed in Taowan Group in the northern margin of the East Qinling orogenic belt, with obvious plastic deformation, and the distribution of which was strictly controlled by fracture belt, was formed in the process of tectonic activities of Luonan Luanchuan fault zone from late Caledonian to early Hercynian by carbonate rock. Therefore, environmental analysis on the formation of metamorphism and deformation features of the carbonate mylonite can reveal the kinematics and dynamics characteristics of tectonic activities of Luonan Luanchuan fault zone in this period. Through detailed field observation and measurement, combined with microstructural analysis and calculation of temperature and pressure conditions, metamorphic facies is low greenschist facies, and deformation mechanism is plastic deformation based on dynamic recrystallization and fine grained role. Mylonite formation temperature is 350~420℃, differential stress 50~110MPa. Strain ellipsoid form displays Taowan Group for strong compression deformation. So the metamorphism and deformation of carbonate mylonite of Taowan Group was formed in a strongly oblique compressional collision environment, as a result of subduction and collision of Qinling micro continental block to North China plate.
