Do S-type granites commonly sample infracrustal sources? New results from an integrated O, U–Pb and Hf isotope study of zircon

Paleoproterozoic S-type granites in the Helanshan Complex, Khondalite Belt, North China Craton: Implications for rapid sediment recycling during slab break-off

“…The granites contain peraluminous minerals (i.e., muscovite), have >1% normative corundum (Table 1) (Lackey et al, 2008). The wide range of oxygen isotope compositions and high ␦ 18 O values are typical of S-type granites (e.g., Kemp et al, 2008;Appleby et al, 2010;Dan et al, 2014). All of these lines of evidence indicate that the Helanshan granites can be classified as S-type.…”

Geochronology, geochemistry, and isotope compositions of Piaochi S-type granitic intrusion in the Qinling orogen, central China: Petrogenesis and tectonic significance

“…Wang et al, 2013;Zhu et al, 2009). Appleby et al (2010) emphasized that magmatic zircon crystals with relatively low δ 18 O in Scottish Caledonian S-type granites, showing a systematic linear variation in δ 18 O and ε Hf values, might result from mixing of supracrustal material with depleted mantle component. More recently, it has been documented that cryptic mantle input in the formation of S-type granites from Scottish Caledonides is supported by the initial Nd and Hf isotope ratios (Fowler et al, 2013).…”

“…Since the term "S-type" granite was firstly proposed by Chappell and White (1974) to depict its supracrustal or sedimentary origin based on whole-rock geochemical features of granites from the Lachlan Fold Belt, its petrogenesis and tectonic setting have become hottest debates in granite petrology (Appleby et al, 2008(Appleby et al, , 2010Champion and Bultitude, 2013;Chappell andWhite, 1992, 2001;Clemens and Stevens, 2012;Collins and Richards, 2008;Fowler et al, 2013;Gray, 1984;Keay et al, 1997;Kemp et al, 2007Kemp et al, , 2009Li et al, 2009a; S-type granites are present and in some cases abundant in orogenic belts. Many studies have been devoted to investigate their petrogenesis and geodynamic setting (e.g.…”

“…While whole-rock data often give average information of magma composition, zircon, a common refractory accessory mineral in granitoid rocks, can retain textural and micro-chemical information about the evolution of its host melt (Appleby et al, 2010). Zircon Hf-O isotopes combining with U-Pb age have been proved to be an efficient approach to clarify the evolution of S-type granitic magma and effectively constrain the relative contributions of mantle material (Appleby et al, 2010;Guo et al, 2012;Kemp et al, 2007Kemp et al, , 2009Li et al, 2009a;Villaros et al, 2012;Wang et al, 2013a,b; X.L.…”

Implications from zircon-saturation temperatures and lithological assemblages for Early Permian thermal anomaly in northwest China

“…2; Jahn, 2004;Renna et al, 2006Renna et al, , 2007. Inherited zircon cores have been reported for the samples from European orogenic belts (Appleby et al, 2009;Clemens et al, 2009;Skjerlie, 1992;Zeck et al, 2007), hence their zircon saturation temperatures represent maximum estimates for the formation temperature of granitoids. 44 samples for Caledonides and 63 samples for Hercynides give zircon saturation temperatures from 731 to 884°C with majority being b 800°C (Fig.…”
