The Shanggong gold deposit, Eastern Qinling Orogen, China: Isotope geochemistry and implications for ore genesis

Petrogenesis of the early Cretaceous Funiushan granites on the southern margin of the North China Craton: Implications for the Mesozoic geological evolution

“…The Triassic Luan-Chuan suture zone between the Qinling micro-continent and the NCC (Li et al, 1993;Liu and Zhang, 2008) probably played a major role for the regional alignment of the granites (Wang et al, 2007a;Guo et al, 2009). Therefore, the extensional event was considered to be related to the evolution of the QOB (Chen et al, 2008b;Wang et al, 2008;Guo et al, 2009). Zhang et al (1996) proposed that continental collision in the QOB took place during the early Mesozoic (245-235 Ma) with an intracontinental subduction in its early stage.…”

Isotope geochemistry and its implications in the origin of Yangla copper deposit, western Yunnan, China

“…CO 2 was collected, condensed, and separated in a liquid nitrogen-alcohol cooling trap (-70°C) for δ 13 C mass spectrometry analysis. Total uncertainties were estimated to be better than ±0.2‰ for δ 13 C (Chen et al, 2008). The hydrogen and oxygen isotopic compositions of 18 samples were analyzed on the MAT 252 mass spectrometer at the Stable Isotope Laboratory of the Institute of Geology, Chinese Academy of Geological Sciences, Beijing, China.…”

Geology, geochronology and isotopic geochemistry of the Xiaoliugou W–Mo ore field in the Qilian Orogen, NW China: Case study of a skarn system formed during continental collision

“…Based on the ore deposit geology, geochronology, and S-Pb-D-O isotope data of the Xiaoliugou W-Mo ore field, and in comparison with similar magmatic-hydrothermal deposits (i.e., Qinling and Dabie orogens, east-central China, Chen and Fu, 1992;Chen et al, 2004Chen et al, , 2008Chen, 2006Chen, , 2013Li et al, 2011aLi et al, , b, 2012aLi et al, , b, c, 2013Yang et al, 2012Yang et al, , 2013aYang et al, , 2013bYang et al, , 2014Deng et al, 2013aDeng et al, ,b,c, 2014aDeng et al, ,b, 2015Liu et al, 2014Wang et al, 2014;Mi et al, 2015), we conclude that the Xiaoliugou W-Mo ore field is a skarn W-Mo ore-forming system generated in a continental collision setting (Fig.9). …”
