Oceanic Spreading and Continental Rifting in Ross Sea, West Antarctica Academic Article uri icon


  • Abstract The initial process of rifting of continental lithosphere is not well understood and has been the focus of research for many years. Analysis of marine magnetic anomalies indicates relatively slow extension between East and West Antarctica from about 43 to 26 Ma that, in the Ross Sea, is focussed along the its western margin. Magnetic anomalies of this age associated with new ocean crust formation in the Adare Basin off north-western Ross Sea, can be traced directly into the Northern Basin that underlies the adjacent …
