The Paleomagnetic Investigation of Antarctica. 1. Paleomagnetism of Hut Point Peninsula Valcanic Sequence

P(論文) Paleomagnetic studies of 10 basaltic rock masses collected from the Hut Point Peninsula of Ross Island, Antarctica, gave the following main results. (a) The positions of virtual paleomagnetic pole (VGP) (8 normals and 2 reverses) are within a polar cap area of about 30° in radius. (b) A synthe...

Description
Summary:P(論文) Paleomagnetic studies of 10 basaltic rock masses collected from the Hut Point Peninsula of Ross Island, Antarctica, gave the following main results. (a) The positions of virtual paleomagnetic pole (VGP) (8 normals and 2 reverses) are within a polar cap area of about 30° in radius. (b) A synthetic summary of paleomagnetic, geological and geochronological data gives a time sequence of geologic history in this area, from the younger to the older, as Twin Crater Sequence (Brunhes epoch), Half Moon Crater (Jaramillo event), Observation Hill and Cape Armitage Sequence (Matuyama epoch), and Crater Hill and Castle Rock Sequence (older than Gilsa event). departmental bulletin paper
