Composition and evolution of the Ancestral South Sandwich Arc: Implications for the flow of deep ocean water and mantle through the Drake Passage Gateway

“…It is worth noting that granitic rocks were dredged from bathymetric highs south of Discovery Bank, so supporting the hypothesis for a thinned continental crustal setting for the arc (e.g. Vuan et al, 2005;Lodolo et al, 2010). However, rifted, older arc crust might also appear continental so a fully intra-oceanic arc cannot entirely be ruled out.…”

“…Banks is largely unknown (Lodolo et al, 2010) although seismic and gravity surveys provide evidence that they probably represent thinned continental crust (e.g. Galindo-Zaldivar et al, 2006).…”

Deep-sea pre-glacial to glacial sedimentation in the Weddell Sea and southern Scotia Sea from a cross-basin seismic transect

Control of sedimentation by active tectonics, glaciation and contourite-depositing currents in Endurance Basin, South Georgia

“…However, in general features identified on the South Scotia Ridge have a greater association with transtension (Galindo-Zaldívar et al, 1996;Bohoyo et al, 2007;Lodolo et al, 2010;Civile et al, 2012) than the left-lateral transpression documented on the northern margin of Endurance Basin in this paper.…”

“…Similar continental margin-parallel marginal basins associated with local transpression and negative free-air gravity anomalies are observed along the northern margin of the sinistral South Scotia Ridge west of the South Orkney micro-continent (Galindo-Zaldívar et al, 1996;Bohoyo et al, 2007;Lodolo et al, 2010). However, in general features identified on the South Scotia Ridge have a greater association with transtension (Galindo-Zaldívar et al, 1996;Bohoyo et al, 2007;Lodolo et al, 2010;Civile et al, 2012) than the left-lateral transpression documented on the northern margin of Endurance Basin in this paper.…”
