Tracking the influence of a continental margin on growth of a magmatic arc, Fiordland, New Zealand, using thermobarometry, thermochronology, and zircon U‐Pb and Hf isotopes

Abstract: Geothermobarometric, radiogenic isotopic and thermochronologic data are used to track the influence of an ancient continental margin (Western Province) on development of an adjacent Carboniferous‐Cretaceous magmatic arc (Outboard Median Batholith) in Fiordland, New Zealand. The data show a record of complicated Mesozoic Gondwana margin growth. Paragneiss within the Outboard Median Batholith is of Carboniferous to Jurassic age and records burial to middle crustal depths in Late Jurassic–Early Cretaceous during … Show more

“…By contrast, granulites in magmatic arc roots commonly witnessed a high geothermal gradient of N 20°C/km (Bohlen, 1987;Ellis, 1987;Harley, 1989;Bohlen, 1991;Ringuette et al, 1999;Müntener et al, 2000;Bhowmik et al, 2005;Brandt et al, 2006;Zhang et al, 2013;Zhao & Zhai, 2013). In general, plate convergence and magma accretion resulting in crustal thickening and growth, and associated HT/UHT granulite-facies metamorphism and anatexis may be one of the most important processes in subduction-related magmatic arcs (e.g., Gibson et al, 1988;Brown, 1996;Clarke et al, 2000;Collins, 2002aCollins, , 2002bHollis et al, 2003; Hyndman et al, 2005;Currie & Hyndman, 2006;Klepeis et al, 2007;Scott et al, 2009;Stowell et al, 2010;Yin et al, 2014).…”

“…Calculated oHf (t) values for the c. 343 Ma William Granite (Takaka Terrane) show a larger range of more primitive values ('4.1 to '9.9; Scott et al 2009) than the range of primitive oHf(t) exhibited in Zetland Diorite zircon (Buller Terrane; '0.9 to '5.8; R. Turnbull unpublished data). The large range in oHf(t) for the Zetland Diorite is in contrast to a restricted range in zircon d 18 O ('7.4 to '7.8; R. Turnbull unpublished data), which implies a heterogeneous mantle and/or lower crustal mafic source and very limited Greenland Group supracrustal input.…”

“…It has also affected parts of central Fiordland (Fig. 1) (Ireland & Gibson 1998;Daczko et al 2009;Scott et al 2009a) and northern Fiordland (Scott et al 2009b). Quantitative P-T estimates for the Fiordland Early Carboniferous metamorphic fabrics yielded values of c. 6-8 kbar and ≤ 650°C (Ireland & Gibson 1998;Scott et al 2009a,b).…”
