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

“…Marini and Maury, 2005), Banda (e.g. Elburg et al, 2005;Nebel et al, 2011) and Bismarck (e.g. Holm and Richards, 2013;Woodhead et al, 2010;Cunningham et al, 2012) arcs, oblique subduction as in the northern Mariana arc (e.g.…”

Obsidian sources and distribution systems in Island Southeast Asia: a review of previous research

“…The Banda Arc in the southeast of the study area is situated on the continental margin of the Sunda Shelf and has a particularly complex orogeny. The Banda Arc is separated into an inner volcanic arc, the subduction zone of the Australian plate, and an outer non-volcanic arc, which accreted in the Neogene to the Sunda shelf moving at the same rate as the Australian Plate (Elburg et al, 2005). The Outer Banda Arc was formed in the Permian to Quaternary ages and consists mainly of metamorphic and sedimentary rocks, with only a few igneous facies (Hall, 2002).…”

The Fazenda Gavião granodiorite and associated potassic plutons as evidence for Palaeoproterozoic arc-continent collision in the Rio Itapicuru greenstone belt, Brazil

“…The magmatic evolution observed in active and recent arccontinent collisions on the west Pacific (e.g., Van Berger at al., 1993;Elburg and Foden, 1998;Elburg et al, 2002Elburg et al, , 2005Wang et al, 2004;Huang et al, 2006) provides important information to interpret ancient orogens as remnants of island arc-continent collision (e.g., Corriveau, 1990;Draut and Clift, 2001;Draut et al, 2002Draut et al, , 2009Brown et al, 2006;Chew et al, 2007;Gordienko et al, 2007, Van Staal et al, 2007.…”

“…The enrichment of potassium and other incompatible elements in igneous rocks emplaced during arc-continent collision is interpreted as a consequence of progressive involvement of continental material (e.g., continental igneous and metamorphic rocks and passive margin sediments) (e.g., Elburg et al, 2005), melt contributions from an enriched/metasomatised sub-continental lithospheric mantle (e.g., Polvé et al, 1997;Draut et al, 2004;Wang et al, 2004), and fractional crystallization (Draut et al, 2009).…”

“…In active and "recent" arc-continent collisions on the western Pacific the observed magmatic evolution from low-middle-K calc-alkaline to high-K to potassic plutonic rocks (e.g., Van Bergen et al, 1993;Elburg et al, 2002Elburg et al, , 2005Wang et al, 2004;Huang et al, 2006) provides important information to interpret ancient orogens as remnants of island arc-continent collision (e.g., Draut and Clift, 2001;Brown et al, 2006;Chew et al, 2007;Gordienko et al, 2007).…”
