“…The lower Cretaceous Dashuang Formation, with U-Pb ages ranging from c. 140 to 135 Ma (Liu et al, 2012), consists of rhyolite, ignimbrite, tuffaceous rhyolitic lava, andesite, basalt, and rhyolitic porphyry, intercalated with subordinate sandstone, silty mudstone and coal horizons. This formation has been interpreted to result from low-angle subduction of the Paleo-Pacific plate (Liu et al, 2012).…”

“…An emerging consensus exists that significant extension occurred across the SCB in the early Cretaceous, driven by a change in subduction from low-to high-angle and consequent roll-back of the subduction zone (e.g., Li and Li, 2007;Zhou and Li, 2000;Zhou et al, 2006;Dong et al, 2008;Shen et al, 2008;Shu et al, 2009;Liu et al, 2012;Li et al, 2014). The consistent early Cretaceous ZFT ages of our samples could arise in this model from widespread structural unfoofing and footwall erosion of normal faults across this broad extensional domain (Fig.…”

“…In addition, the zircon U-Pb dating method has much smaller systematic error than the K-Ar and Rb-Sr methods. Therefore, the zircon U-Pb dating method would be the most appropriate dating method for multi-stage magmatic activities, and it has been widely used (e.g., Condie et al, 2009;Li et al, 2008;Li et al, 2011;Liu et al, 2012;Wan et al, 2006;Ye et al, 2007;Zhu et al, 2013). To mitigate the effect of dating methods, the following discussions based primarily on the zircon U-Pb data.…”

The widespread occurrence of late Mesozoic volcanic rocks in the Gan-Hang Belt in South China is associated with similarly widespread mineralization, but many important questions surrounding these volcanic rocks have not been clearly answered. The Tianhuashan basin located in the northern Wuyi Mountain volcanic belt is one of the most important volcanic basins in the Gan-Hang Belt, and it is primarily composed of the Daguding and Ehuling Formations and their intrusive counterparts. LA-ICP-MS zircon U-Pb dating shows that the Daguding Formation erupted in the Late Jurassic (152-160 Ma), whereas the Ehuling Formation erupted in the Early Cretaceous (131-139 Ma) in the Tianhuashan basin. Volcanic rocks are rhyolite and share similar trace and rare earth element patterns with an enrichment of LREEs and a depletion in Sr, Ba, Nb, Ta, P, Eu and Ti. They are also characterized by negative whole rock ε Nd (t) and zircon ε Hf (t) values with Paleoproterozoic t 2DM ages, suggesting that they were derived primarily from the remelting of ancient crustal materials. Daguding volcanic rocks are strongly peraluminous and show a higher Mg# than pure crustal melts, implying that they were likely derived from Paleoproterozoic metasedimentary basement materials. However, Ehuling volcanic rocks are weakly peraluminous and have a pronounced A 2 -type geochemical signature. Detailed elemental and isotopic data suggest that they were formed by the partial melting of the Paleoproterozoic metamorphic basement (including metasedimentary and metaigneous rocks) at a high temperature (~840°C), followed by fractional crystallization. These results imply that during the Late Jurassic, South China on the Gan-Hang Belt was a continental arc coupled with the subduction of the Paleo-Pacific plate. Since the beginning of the Early Cretaceous, an intra-arc rift has formed along the Gan-Hang Belt as a consequence of slab rollback. These results also indicate that the extension in the Gan-Hang Belt began later than the southwestern part of the Shi-Hang Zone and lasted from A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT2 139 Ma to 122 Ma.

“…10b), reflecting an increasing contribution of mantle-derived magma during the Early Cretaceous. Similarly, zircon saturation temperatures and zircon e Hf (t) values of episodic felsic volcanic rocks in the eastern part of the GHTB have also shown remarkable increases during the same period (Li et al, 2014;Liu et al, 2012Liu et al, , 2014, also implying the intensified crust-mantle interaction in Southeast China. In this study, detailed petrologic and geochemical studies of the Early Cretaceous granitoids and their MMEs confirm that magma mixing and crust-mantle interaction progressively intensified from $135 Ma to $112 Ma in Southeast China.…”
