Petrogenesis of the Mesozoic granites and Mo mineralization of the Luanchuan ore field in the East Qinling Mo mineralization belt, Central China

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

“…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). Nevertheless, it remains unclear if the mantle-derived components were involved in the petrogenesis of these granitic intrusions, and to what extent basaltic melts are required (e.g.…”

Formation timing and genesis of Madiu fluorite deposit in East Qinling, China: Constraints from fluid inclusion, geochemistry, and H–O–Sr–Nd isotopes

“…The Central China Orogen (CCO) is bounded by the North China Craton to the north and the Yangtze Craton to the south (Figure a), extending ~4,000 km from the West Kunlun Orogen to the Sulu Orogen (Bao et al, ; Tang et al, ). As an important part of the CCO, the East Qinling Orogeny comprises four belts (Figure b), including the Huaxiong Block (or Southern North China Craton), North Qinling Belt, South Qinling Belt, and Songpan Belt (Chen & Santosh, ).…”

“…Late Mesozoic granitic batholiths and stocks are widespread in the Xiong'ershan–Waifangshan area. For instance, the Wuzhangshan batholith (157 Ma; Mao et al, ), Huashan granite batholith (142.2–131.0 Ma; Li, ; Mao et al, ), and Heyu granite batholith (150–133 Ma; Zhou, ; Gao, Zhang, et al, ; Li et al, ; Zhu, Chen, Liu, & Siebel, ; Bao et al, ) intruded into the Precambrian Taihua and Xiong'er groups and are interpreted as the products of Late Jurassic to Early Cretaceous large‐scale extension or lithospheric thinning of the North China Craton (Mao et al, , ; Mao et al, ; Tian et al, ; Zhang et al, ). The regional Mo–W, Pb–Zn–Ag, and Au mineralization are spatio‐temporal related with granitic intrusions and are associated with the Early Cretaceous tectono‐magmatic event (Deng, Chen, et al, ; Mao et al, ).…”

“…The Heyu fluorite district, with a total of over 10 Mt indicated resource at 50% fluorite, is a new and prosperous fluorite producer in China (Deng et al, ). Over 14 vein‐type fluorite deposits have been discovered in the Heyu biotite monzogranite batholith, encompassing an area of 784 km 2 (Bao, Wang, Zhao, Li, & Gao, ; Deng, Zhang, et al, ). The orebody occurrences are featured by their shallow depths and by continuous, NW‐/NE‐striking steep fault‐controlled ore veins.…”

Petrogenesis of the early Cretaceous intermediate and felsic intrusions at the southern margin of the North China Craton: Implications for crust–mantle interaction

“…Li et al, 2012;Zhao et al, 2012;Zhu et al, 2013) or from the subducted Yangtze Craton (e.g. Bao et al, 2014). There is a consensus that underplating of the mantle-derived magmas triggered partial melting of the lower crust (Bergantz, 1989;Y.G.…”
