Generation of Late Cretaceous silicic rocks in SE China: Age, major element and numerical simulation constraints

Multi-stage crust–mantle interaction in SE China: Temporal, thermal and compositional constraints from the Mesozoic felsic volcanic rocks in eastern Guangdong–Fujian provinces

“…felsic lavas and subordinate basalts occurred. (7) From 130 to 110 Ma, the region experienced NE-trending strike-slip faulting, leading to mylonitization of the granites and reactivation of large-scale faults (Chen et al, 2008a;Li et al, 2003;Zhao et al, 2007). (8) Eruption of the Shimaoshan Fm.…”

“…In the past decades, there have been many publications discussing the tectonic regime that controlled the Mesozoic mafic magmatism in SE China (e.g., Chen and Jahn, 1998;Chen et al, 2008a;Dong et al, 2006;Huang et al, 2008;Lapierre et al, 1997;Li and Zhou, 2001;Li et al, 2009a;Sun and Zhou, 2002;Wang and Zhou, 2002;Xing et al, 2007;Yang et al, 1999;Zhou and Li, 2000). For instance, Lapierre et al (1997) and Zhou and Li (2000) related the origin of the mafic rocks to subduction of the Paleo-Pacific plate.…”

“…considered that late Mesozoic magmatism was linked to flat subduction of the Paleo-Pacific Ocean and the subsequent retreat and foundering of the subducted slab. By contrast, Chen et al (2008a) considered that the origin of the Jurassic basalts in South China had no direct relationship with the subduction of Paleo-Pacific slab, and Fan et al (2003a) suggested that lithospheric extension was responsible for the eruption of the Mesozoic basalts in Jiangxi and Hunan provinces. Also, Li (2000) proposed that the multiple Cretaceous mafic magmatic events were genetically linked with the episodic lithospheric extension.…”

Zircon LA-ICPMS U–Pb ages and Hf isotopes of Huayu (Penghu Islands) volcanics in the Taiwan Strait and tectonic implication

“…Major products mainly involve Jurassic and Cretaceous intrusive and extrusive rocks, in which the Cretaceous igneous rocks define the Southeast Coast Magmatic Belt. Recent geochronological and geochemical studies reveal a general regularity of the Cretaceous magmatic evolution over this Belt: shallow intrusions of I-type granitoids occurred at 110-99 Ma, near surface intrusion of A-type granite at 110-91 Ma (peaked at 94-91 Ma), and rhyolite-dominating basalt/rhyolite bimodal volcanism at 101-81 Ma (Martin et al, 1994;Chen et al, 2004Chen et al, , 2008aHsieh et al, 2009). Although appeared to be in small volumes, some younger andesite-rhyolite associations are also present in the Southeast Coast Magmatic Belt.…”

“…Although appeared to be in small volumes, some younger andesite-rhyolite associations are also present in the Southeast Coast Magmatic Belt. For example, the age reported for the Lingtongshan rhyolite of southern Fujian is 72 Ma (Chen et al, 2008a). Further extending to eastern Guangdong, Zhu et al (2004) reported the occurrence of the Late Cretaceous/Early Cenozoic basalt-andesite-dacite associations.…”
