Northern Victoria Land is located at the boundary between an extended, presumably hot, region (West Antarctic Rift System, WARS) and the thick, possibly cold East Antarctic craton. The style and timing of Tertiary deformation along with relationships with the magmatic activity are still unclear, and...
