Paleomagnetic investigation of McMurdo volcanics, Antarctica
A total of 212 paleomagnetic samples were collected from the Hut Point Peninsula, the Cape Royds and the Taylor Valley in the McMurdo Sound, Antarctica. These samples have stable natural remanent magnetization. The results of paleomagnetic studies are as follows : (1) The position of Antarctica has...
