Document title

Revised interpretation of tectonic features in the southern Weddell Sea, Antarctica, from new seismic data

Abstract

The new data give more detailed insights into the structure and evolution of the Explora Escarpment. To the west (19° W) the escarpment vanishes as a topographic feature. We interpret a newly discovered structure, denominated Polarstern Bank (71° 30'S, 25° W, the proposed plate boundary) as the result of an uprising of the basement during the Late Cretaceous. We propose that the Explora Escarpment and the Andenes Escarpment have different genetic origins. - (L'A.)
