The South Scotia Ridge is studied by swath bathymetry, multichannel seismic and magnetometry
profiles, obtained during the HESANT 92/93 cruise. The ridge is composed by thinned continental crust
fragments and to the north contacts by a sinistral transpressive faull wilh the oceanic crust of the Scotia
Sea. Another fault located to the south bounds the ridge with the oceanic crust of the Powell Basin. The
most significant active deformation lies in the axial depression of the ridge, within a band delineated by
fault systems with WSW-ENE and SW-NE strikes, which separate the northern and southern blocls of the
ridge. The northern block is being fragmented from the Antarctic Plate by a zone of transtensive faults,
and is probably a independient crustal element.
