内容記述 |
Two ^<40>Ar-^<39>Ar and five K-Ar ages and the virtual geomagnetic pole (VGP) were obtained for metadolerite dikes and gneiss at three sites, 1550 Nunatak, Brattnipane and Austkampane of the Sør Rondane Mountains, Antarctica. The radiometric age of 1550 Nunatak was determined to be 440-450 Ma, which is the youngest one so far reported in this area. The obtained VGP is similar to those estimated from rocks of the other area in Antarctica in Cambrian-Ordovician age, but is different from that reported by J.D.A. ZIJDERVELD (J. Geophys. Res., 73,3773,1968). |
