The Rb-Sr isotopic data demonstrate that the complete Sr isotopic homogenization occurred among K-feldspar, plagioclase, biotite and whole-rock, and define isochron ages of 482.5±9.5,468.9±7.8 and 493.3±4.5 Ma for rocks from Syowa Station, Skarvsnes and the Yamato Mountains, respectively. These ages probably represent the time of cooling after the regional metamorphism or granite intrusion.
