Petrogenesis of the Nanling Mountains granites from South China: Constraints from systematic apatite geochemistry and whole-rock geochemical and Sr–Nd isotope compositions

Origin of the granulite enclaves in Indo-Sinian peraluminous granites, South China and its implication for crustal anatexis

“…13; Deng, 2003;Deng et al, 2004;Chen et al, 2011;Hsieh et al, 2008;Qi et al, 2007). Compared to the granulite enclaves, the Stype granites show less variation in 87 Sr/ 86 Sr(i) and similar ε Nd (t) and ε Hf (t) (Zhao et al, 2010; this study).…”

“…Using a Zr saturation Fig. 13.`8 7 Sr/ 86 Sr(i) vs. ε Nd (t) diagram of the granulite enclaves and the host granites in the DSGB and comparison with the LFB S-type and I-type granites (Collins, 1996;King et al, 1997;McCulloch and Chappell, 1982 Qi et al (2007), and Hsieh et al (2008). method of whole-rock geochemistry (Miller et al, 2003;Harrison, 1983, 2005), the temperature for the granites from the DSGB was calculated as 800-900°C.…”

“…Metasedimentary granulite enclaves are abundant in the Indo-Sinian peraluminous granites from the DSGB. In recent years, many papers have been published discussing the origin of these granites (e.g., Charoy and Barbey, 2008;Chen et al, 1995Chen et al, , 2011Deng, 2003;Deng et al, 2004;Fang, 1989;Hsieh et al, 2008;Peng et al, 2004;Qi et al, 2007;Zhao et al, 2010Zhao et al, , 2011, and their hosting granulite enclaves (e.g., Du et al, 1999;Pang, 2001;Peng, 2006;Peng et al, 2004;Wang, 1987;Zhao et al, 2010Zhao et al, , 2011. Two possible tectonic settings of the granitic magmatism have been proposed: (1) anatexic products formed during continental collision (e.g., Chen et al, 1995Chen et al, , 2011Deng, 2003;Deng et al, 2004;Fang, 1989;Hsieh et al, 2008;Qi et al, 2007); and (2) crustal melts of post-collisional extension (e.g., Charoy and Barbey, 2008;Peng et al, 2004;Zhao et al, 2010Zhao et al, , 2011.…”

Multi-chronometric dating of the Huarong granitoids from the middle Yangtze Craton: Implications for the tectonic evolution of eastern China

“…These magmatic rocks are economically important due to their Cu-Au-Mo mineralization. They also serve as geodynamic tracers of the regional tectonic evolution (Li, 2000;Davis et al, 2002;Liu et al, 2004;Wu et al, 2005;Hiseh et al, 2008;Chen et al, 2009;Pirajno et al, 2009;Li et al, 2009Li et al, , 2010aZhu et al, 2010b). The petrogenesis and geodynamic setting of these magmatic rocks are still controversial with three models.…”

Petrogenesis of early Jurassic basalts in southern Jiangxi Province, South China: Implications for the thermal state of the Mesozoic mantle beneath South China

“…The tholeiitic character of the Early Jurassic basalts is therefore attributed to a slightly hotter mantle temperature at a shallower depth. Moreover, because the 190 Ma and the Hunan strongly peraluminous granite (Wang et al, 2007a;Hsieh et al, 2008) are also shown. The AFC trend (pentagram marks) are shown at 0.1 intervals.…”
