“…Figures modified from Korhonen et al (2010b). at pressures of 0.75 -1.15 GPa and temperatures of c. 870 8C, and a Cretaceous event at pressures of 0.60-0.75 GPa and temperatures of 830 -870 8C (Korhonen et al 2010a(Korhonen et al , 2012. Elevated temperatures and crustal melting in the Palaeozoic are attributed to thickening of the continental margin during calc-alkaline arc magmatism represented by the Ford Granodiorite suite (Pankhurst et al 1998;Siddoway & Fanning 2009), and in the Mesozoic are attributed to moderate thickening followed by lithosphere thinning during intracontinental extension across the West Antarctic rift system (Siddoway 2008). Coeval with Cretaceous rifting, mafic dykes of c. 113 Ma to c. 98 Ma age were intruded throughout the Fosdick complex (Saito et al 2013).…”

“…In Marie Byrd Land, both the Swanson Formation and the Ford Granodiorite suite are intruded by the Lower Cretaceous Byrd Coast Granite suite (Fig. 1c;Adams 1987;Siddoway 2008), which is the main plutonic phase emplaced during the intracontinental extension that preceded break-up of Marie Byrd Land (Siddoway et al 2004b(Siddoway et al , 2005McFadden et al 2010a) and Zealandia (Mortimer 2004).…”

“…Tectonic models for the rift system typically invoke phases of extension in the Cretaceous and Cenozoic (Cooper et al, 1987;Tessensohn and Wörner, 1991;Davey and Brancolini, 1995;Salvini et al, 1997;Fitzgerald, 2002;Karner et al, 2005;Huerta and Harry, 2007;Bialas et al, 2007;Siddoway, 2008;Wilson and Luyendyk, 2009). Seismic studies indicate at least two distinct periods of Cenozoic rifting (Paleogene and Neogene) within the western Ross Sea.…”

“…Rifting was also widespread in West Antarctica at c. 100 Ma, resulting in extension, A-type magmatism and metamorphism in Marie Byrd Land. This was linked to development of the West Antarctic Rift System (Mukasa & Dalziel 2000;Siddoway 2008), and the separation of New Zealand and other blocks away from West Antarctica (Mortimer 2004), leaving Antarctica in more or less its presentday configuration.…”
