Tectonics of South China: Key to understanding West Pacific geology

Mesozoic large magmatic events and mineralization in SE China: oblique subduction of the Pacific plate

“…Hsu 1943;Gilder et al 1991;Zhou and Li 2000;Zhou et al 2006;Zhang et al 2007a;Chen et al 2008). Several tectonic models have been postulated to explain the Mesozoic evolution of SE China (Hsü et al 1990;Gilder et al 1991;Li 2000;Zhou and Li 2000;Wang et al 2003;Zhou et al 2006;Chen et al 2008;Wong et al 2009). Most models can be classified into one of two types: an active continental margin related to the northwestward subduction of the Pacific plate in the Mesozoic (Jahn et al 1990;Zhou and Li 2000;Zhou et al 2006;Chen et al 2008); or an intraplate lithospheric event, for example, a result of the closure of an oceanic basin in the SE China interior (Hsü et al 1990;Li 1998).…”

Other models, such as wrench faulting and/or continental rifting and extension (Gilder et al 1991;Li 2000;Wang et al 2003Wang et al , 2005c, have also been proposed based on the intracontinental lithospheric extension and thinning since the early Mesozoic (Wang et al 2006).…”

Kwangsian and Indosinian reworking of the eastern South China Block: Constraints on zircon U–Pb geochronology and metamorphism of amphibolites and granulites

“…The temporal and spatial patterns and P-T path of both metamorphic events are poorly known. There are also additional disputes on (1) whether the timing of the metamorphism coincides with those of magmatism and deformation for each event in the SCB, and (2) whether these events are related to either the subduction/ collision between the Yangtze and Cathaysia Blocks or intracontinental reworking within the SCB (e.g., Holloway, 1982;Hsü et al, 1990;Li and Li, 2007;C. Li et al, 2010;Z.X.…”

SHRIMP zircon U-Pb ages and tectonic implications for Indosinian granitoids of southern Zhuguangshan granitic composite, South China

“…These include the collision orogenic model [33][34][35], the intracontinental orogenic subduction model [36], a model involving extension, lithospheric thinning and basic magma underplating [37,38], the model of continental collision and crustal thickening [10,31,[39][40][41][42], and the model of flat-slab subduction [43].…”
