Physiography of the Scotia arc. White arrows show path of the Antarctic Circumpolar Current (ACC) through Drake Passage, and outlets through the North Scotia Ridge. Red arrows show relative motion of the South America and Antarctic plates (∼22 mm/yr). White ellipse represents former position of the South Georgia microcontinent (see text). NSR—North Scotia Ridge; SSR—South Scotia Ridge; SFZ—Shackleton Fracture Zone; WSS—west Scotia Sea; CS—central Scotia Sea; ASSA—ancestral South Sandwich arc; ESS—east Scotia Sea. Positive features (clockwise from the northwest): CD—Cordillera Darwin; CH—Cape Horn; SI—Isla de los Estados (Staten Island); BwB—Burdwood Bank; DvB—Davis Bank; BkP—Barker Plateau; BSR—Black and Shag Rocks platform; NEGR—northeast Georgia Rise; HB—Herdman Bank; DB—Discovery Bank; JB—Jane Bank; BB—Bruce Bank; PB—Pirie Bank; TR—Terror Rise.

(a) Map showing the tectonic boundaries in the Scotia arc region. The red line indicates the current tectonic plate boundaries. (b) Map of the study area. The red line represents the Magallanes–Fagnano fault system/South America–Scotia plate boundary. The dark blue line indicates the deformational front of the Austral–Malvinas fold–thrust belt. The focal mechanism is from Forsyth (1975) and Pelayo and Wiens (1989). The yellow polygons indicate the location of the strike-slip basins.

Drake Passage–Scotia arc region physiography and path of Antarctic Circumpolar Current. Physical features (from GeoMapApp, Lamont Doherty Earth Observatory, Columbia University, United States): BkB—Barker Bank (formally proposed name, previously informally Aurora Bank); BwB—Burdwood Bank; BB—Bruce Bank; CSS—central Scotia Sea; DB—Discovery Bank; DvB—Davis Bank; ESS—east Scotia Sea; HB—Herdman Bank; JB—Jane Bank; NGR—Northeast Georgia Rise; PB—Pirie Bank; SFZ—Shackleton Fracture Zone; SRB—Shag Rocks Bank; SSI—South Sandwich Islands; SG—South Georgia microcontinent; SOI—South Orkney Islands microcontinent; TR—Terror Rise; WSS—west Scotia Sea. Ocean currents and fronts (Naveira Garabato et al., 2002): ACC—Antarctic Circumpolar Current; PF—Polar Front; SACCF—South Antarctic Circumpolar Current Front; SAF—Sub-Antarctic Front; SB—southern boundary of the ACC. Note that Polar Front is the core of the flow of Circumpolar Deep Water of the Antarctic Circumpolar Current. White arrows show the three main pathways of ACC. Red and yellow stars show locations of dredge hauls referred to in text from forearc of active South Sandwich Islands (SSI) volcanic arc and Discovery Bank, respectively.

Tectonic setting of Scotia arc region for late Oligocene (25 Ma), late Miocene (10 Ma), and present day (0 Ma). Major continents (South America [SAM], blue; Antarctic Peninsula [ANT], beige) positioned using seafloor spreading data and PLATES software of Institute for Geophysics, The University of Texas at Austin (United States). Latitude and longitude are relative to a hotspot reference frame (see Appendix DR4 [see footnote 1]). Bathymetric contours at 3000, 1000, and 500 m; red lines are oceanic transform faults; toothed red lines are subduction zones with teeth on upper plate; green represents other plate boundaries; black ticks are magnetic anomaly picks (see Appendix DR1); black lines show ocean floor isochrons; blue line is east Scotia Sea backarc spreading center offset by transform faults.
