Subduction zones and their associated slabs are the main drivers of plate tectonics and
mantle flow, but how these zones initiate remains enigmatic. In the Scotia Sea region …

Abstract The Scotia Sea is one of the tectonically most complex and least understood back-
arc basins on Earth, which partly results from its remote location making the acquisition of …

Restraining-and releasing bends with similar morphology and structure have been
described by many previous studies of strike-slip faults in a variety of active and ancient …

Ona Basin is a small intra-oceanic basin located in the southwestern corner of the Scotia
Sea. This region is crucial for an understanding of the early phases of opening of Drake …

The distribution of seismic units in deposits of the basins near the Antarctic–Scotia plate
boundary is described based on the analysis of multichannel seismic reflection profiles. Five …

The major structural and tectonic features of the Fuegian Andes provide an outstanding
onshore geological framework that aids in the understanding of the tectonic evolution of the …

Multichannel and high-resolution seismic profiles complemented with swath bathymetry
show a variety of contourite deposits in the northern Weddell Sea resulting from the …

The plate boundary between the Scotia and Antarctic plates runs along the broadly E–W
trending South Scotia Ridge. It is a mainly transcurrent margin that juxtaposes thinned …

Microcontinents and continental fragments are small pieces of continental crust that are
surrounded by oceanic lithosphere. Although classically associated with passive margin …

A compilation of available multichannel seismic profiles acquired along the southern margin
of the Scotia Sea east of the South Orkney microcontinent has allowed identifying and …
