“…They were considered to be produced by partial melting of the NCC ancient crystalline basement (e.g. Guo et al, 2009;Gao et al, 2010;Ding et al, 2011;Hu et al, 2012;Li et al, 2012b;Zhao et al, 2012), or the subducted continental crust of the Yangtze Craton (e.g. Bao et al, 2014).…”

“…160-135 Ma) in the southern margin of the NCC form a roughly northwest-southeast-trending belt, also implying formation of the thickened crust before late Jurassic ( Fig. 12B; Gao et al, 2010;Li et al, 2012b;Mao et al, 2010;Zhao et al, 2012). In the Waifangshan area, the 148-135 Ma Heyu adakitic pluton marks the transformation of the lithosphere from thickening to thinning in the southern margin of the NCC (Gao et al, 2010;Li et al, 2012b).…”

“…Nevertheless, it remains unclear whether and to what extent mantle-derived components were involved in the petrogenesis of the granitic magmas in the southern margin of the NCC during the late Mesozoic (Ding et al, 2011;N. Li et al, 2012;Zhao et al, 2012) due to lack of evidence of contemporaneous mantle-derived magmatic activity. The key to these debates is to identify primary granites and associated intermediate to mafic rocks.…”

“…Many researchers have demonstrated that the 160-135 Ma adakitic granites were produced by partial melting of thickened lower continental crust Lithos 206-207 (2014) [65][66][67][68][69][70][71][72][73][74][75][76][77][78] (Ding et al, 2011;Gao et al, 2010;N. Li et al, 2012b;Zhao et al, 2012). However, the 130-110 Ma granites are geochemically different from the adakites, and have not yet been well-documented (Ye et al, 2008).…”

The Chen'er gold deposit hosted in the Precambrian Taihua Supergroup metamorphic rocks is one of the typical gold deposits in the Xiaoqinling region along the southern margin of the North China Craton. The metallic mineral assemblage in this deposit includes sulfides, tellurides, native gold, electrum, and native bismuth. The telluride minerals are composed of calaverite, petzite, hessite, altaite, joseite; except for hessite and matildite, the other tellurides and native bismuth are first reported in this study. Fluid inclusion studies in the auriferous quartz reveal three types: aqueous, aqueous–carbonic, and carbonic inclusions. The homogenization temperatures range from 184 to 364°C, and salinities are in the range of 1.74‐ to 11.47‐wt.% NaCl equiv. At temperatures of 275°C, the logfTe2 and logfS2 of the fluid are estimated as −16.13 to −8.19 and −12.74 to −4.80, respectively, and at temperatures of 305°C, the pH and logfO2 of the fluid are estimated as 3.61 to 5.69 and −34.31 to −27.81, respectively. It is inferred that Au(HS)2− and Au(HS)0 are the predominant gold‐bearing complexes, and tellurium was transported as Te22−. Based on thermodynamic models of logfO2(g) versus pH, we suggest that the precipitations of native gold and electrum in the early and main mineralization stages are different, with the oxygen and hydrogen isotope values of auriferous quartz suggesting mixing of magmatic water with meteoric water.
