内容記述 | The central part of the Hidaka Metamorphic Belt (HMB) is divided into six metamorphic zones : lower-biotite, upper-biotite, garnet, sillimanite-muscovite, garnet-cordierite and orthopyroxene zones. A significant temperature gap with lithological contrast is recognized between the sillimanite-muscovite and garnet-cordierite zones. In the garnet-cordierite and orthopyroxene zones, marked prograde zoning profiles occur in garnets in amphibolites. Geothermometry and diffusion modeling for the zoning profiles of these garnets suggest that the rims were formed under upper amphibolite-facies and granulite-facies conditions, with a brief and rapid increase in temperature at peak metamorphism. The latest pulse of SHRIMP zircon dating of granulite (Early Miocene) in the Hidakahorobetsu River area may explain the granulite-facies metamorphism recorded the garnet rims, which occurred just before the uplift episode indicated by K-Ar ages. | |||||||||
