Age and position of the Ellsworth Mountains crustal fragment, Antarctica
The present geographical position of the Ellsworth Mountains is geologically anomalous on account of their stratigraphy, which does not relate to western Antarctica, their structural trend, approximately perpendicular to the trend in adjacent regions, and their relief, the greatest, and possibly the youngest, in Antarctica. These factors suggest that the Ellsworth Mountains are not in their original position but have moved, probably during the Cainozoic.
