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).}, pages = {169--177}, title = {AGE AND PALEOMAGNETIC STUDIES FOR INTRUSIVE AND METAMORPHIC ROCKS FROM THE SØR RONDANE MOUNTAINS, ANTARCTICA}, volume = {1}, year = {1987} }
