In this project, the garnet Staurolite mica schist in xiangtaohu area of central Qiangtang was systematically analyzed by petrology, mineralogy, detrital zircon and Muscovite ar Ar dating. Petrological and mineralogical studies show that the samples underwent the superposition of early blueschist facies and late amphibolite facies metamorphism. Detrital zircon analysis shows that the samples were derived from Carboniferous island arc magmatism in the hanging wall of the subduction zone. The AR AR results of Muscovite are 263-259 Ma, which represents the cooling age of the diapir after it entered the middle and lower crust of the hanging wall. This study reveals the subduction erosion during the subduction of oceanic plate from the perspective of metamorphic evolution for the first time, and suggests that the special rocks exposed in the low temperature / high pressure metamorphic belt may have important implications for identifying the subduction erosion in the ancient subduction zone.

File naming and required software

All data have been saved in Excel. Detrital zircon age data is stored in zircon data file, muscovite Ar dating data in Muscovite ar file, and mineralogical data in minerals data file.
