Rb-Sr mineral isochron ages were determined for three metamorphic rocks around Syowa Station and from the Yamato Mountains, eastern Queen Maud Land. The Rb-Sr isotopic data demonstrate that the complete Sr isotopic homogenization occurred among K-feldspar, plagioclase, biotite and whole-rock, and de...
