“…Furthermore, nearly all samples of volcanic rocks in the Tuen Mun Formation are plotted into the field of arc magmatism in a Ti versus Zr plot (Pearce 1982) (Figure 14). It is thus suggested that the volcanic rocks in the Tuen Mun Formation may have also formed under an arc setting related to the subduction of the Palaeo-Pacific Plate, a setting that was commonly proposed for the widespread Mesozoic igneous rocks in Southeast China (Zhou and Li 2000;Chen et al 2004;Zhou et al 2006;Chen et al 2008b;Wong et al 2009;He et al 2010;Wang et al 2011;Li et al 2012;Liu et al 2012;Cui et al 2013).…”

Generally the prolonged magmatic episode comprises the Indosinian (Late Triassic,, the early Yanshanian (Middle to Late Jurassic,, and the late Yanshanian periods (Early Cretaceous, 140-66 Ma) ( Figure 1).…”

“…These models include the Andean-type continental margin related to subduction (Zhou and Li 2000;Zhou et al 2006;Li et al 2012), intra-plate lithospheric subduction (Hsü et al 1990), continental rifting and extension (Gilder et al 1991;Wang et al 2005), and post-collisional extension (Chen et al 2008b International Geology Review 409 (Zhou and Li 2000;Chen et al 2004Chen et al , 2008bZhou et al 2006;Wong et al 2009;He et al 2010;Wang et al 2011;Li et al 2012;Liu et al 2012;Cui et al 2013). Furthermore, although the transition time is still controversial, recent research shows that change in tectonic setting from compressional to extensional is very likely to have happened in the Late Jurassic to Early Cretaceous (Zhou et al 2006;Chen et al 2008b;Hu and Zhou 2012;Li et al 2012;Cui et al 2013). However, the mechanism of deformation of the interior of Southeast China more than 1000 km from the coast by subduction and the initial age of subduction of the PalaeoPacific Plate are still controversial (Zhou and Li 2000;Zhou et al 2006;Chen et al 2008b;He et al 2010;Li et al 2012).…”

Widespread Mesozoic igneous rocks in Hong Kong form part of the giant Mesozoic igneous province in Southeastern China. The Tuen Mun Formation in the Northwestern New Territories is the oldest volcanic unit known in Hong Kong. This formation contains a lower unit composed of dominantly volcanic breccia, minor dacite, rhyolite, and tuff, and an upper unit of basaltic andesitic to andesitic lava. The volcanic rocks from the lower unit contain zircon grains with a mean U-Pb age of 163.4 ± 0.9 Ma, synchronous with the adjacent Tsuen Wan Volcanic Group in the region. Good inter-correlations between different elements in the Harker diagrams indicate that the volcanic rocks with high SiO 2 (e.g. >65 wt.%) are essentially physical mixtures of intermediate magmas and various xenoliths of country rocks, characterizing the palaeo-volcanic plug facies. Preservation of large amounts of xenoliths of sandstone and marble in the volcanic rocks, which is revealed both in field and under microscopic observation, further supports this hypothesis. The original andesitic magma, represented by the intermediate volcanic rocks with SiO 2 <65 wt.%, exhibit enrichments of LILEs and LREEs compared with N-MORB, but have negative Nb-Ta-Ti anomalies in the primitive-mantle normalized diagram, similar to those derived from metasomatized mantle wedge in an arc environment. Large ranges of SiO 2 , MgO, and CaO contents, and negative Eu and Ce anomalies are consistent with significant fractional crystallization of likely olivine/pyroxene and plagioclase. We propose that during the Late Jurassic subduction of the Palaeo-Pacific Plate underneath the coastal continental arc in Southeast China generated prolonged and cyclic volcanism in the northern part of Hong Kong.

“…Mesozoic intrusive rocks are widespread in SE China (Bai et al, 2015;Cui et al, 2013;Zhou et al, 2013), among which the occurrence of a 500 km long and 60 km wide NE-trending miarolitic alkaline granite belt, in Fuzhou county, Fujian province, is magnificent. The miarolite belt, subparallel to the coastline, occurs along the Changle-Xiamen rift and consists of around ten miarolitic complexes including the Guanshan-, Jiantian-, Guian-, Danyang-, Fuzhou-, Kuiqi-and Bijiashan pluton (Wu, 1991).…”

The tectonic evolution of Southeast China during Late Mesozoic is a prominent topic. Numerous tectonic models on Late Mesozoic evolution of Southeast China have been published in the past 50 years. We synthesized many up-to-date and precise zircon U-Pb ages, sedimentary strata, and regional structures and discussed the oxygen fugacity of magmas and related ore deposits. We also analyzed the most current tectonic models published by some scholars. A multistage tectonic stress evolution history during Late Mesozoic was constructed, which included the following stages: 1) Early-Middle Jurassic (196-175 Ma) extension, in which many bimodal volcanics formed; 2) Middle-Late Jurassic (165-140 Ma) compression, which generated largescale gneissic granites, garnet-bearing granites, stratigraphic hiatus, and nappe structures; 3) Early Cretaceous (140 ± 5-120 Ma) extension, which formed weakly deformed or undeformed granites, alkali granites, metamorphic core complexes, graben basins, and basic dike swarms; 4) Early Cretaceous (120-110 Ma) compression, which generated nappe structures, volcanic hiatuses, and garnet-bearing granites; and 5) Early-Late Cretaceous (110-80 Ma) extension, which generated largescale bimodal volcanics, basic dike swarms, alkali granites, and graben basins. The Late Mesozoic tectonic evolution of Southeast China may be attributed to the drifting history of the Paleo-Pacific plate. The drifting direction of the Paleo-Pacific plate has changed several times since 140 Ma, which led to major changes in the tectonicphenomena from Jurassic to Cretaceous and to the formation of Late Mesozoic mineral deposits.
