Cretaceous tectonic evolution of South China: A preliminary synthesis

Initiation and evolution of the South China Sea: an overview

“…2) and major compression across the whole of south China around 100 Ma (Li et al 2014b). This is likely to be the causal mechanism that initiated the southward subduction of the proto-SCS.…”

“…There is no evidence, however, for such an early extension in the SCS. Instead, there was major compression in the whole south China around 100 Ma (Li et al 2014b). Interestingly, paleomagnetic studies show that several of the islands near the southern margin of the SCS were located close to the Eurasian continent at 65 Ma (Lee and Lawver 1995).…”

“…This process may have triggered and promoted the subduction of the proto-SCS. Given that major compression occurred across south China as shown by discontinuities at *100 Ma (Li et al 2014b), it is likely that the ridge subduction started around this time.…”

Middle Jurassic collision of an exotic microcontinental fragment: Implications for magmatism across the Southeast China continental margin

“…1). Although the precise trace of this structure in southeast China is poorly defined, it has been frequently depicted (e.g., Wang et al, 2013a;Li et al, 2014) to intersect the coast in the vicinity of the Hong Kong. Based on mantle and crustal isotope signatures reflected in magmatic rocks, some workers (e.g., Darbyshire and Sewell, 1997;Fletcher et al, 2004;Xu et al, 2007) have postulated that this fault may represent a basement terrane boundary.…”

Adakitic rocks associated with the Shilu copper–molybdenum deposit in the Yangchun Basin, South China, and their tectonic implications

“…A signature of Late Cretaceous (*100 Ma) NeoTethys ridge subduction has been found in the Gangdese belt (Guan et al 2010;Ye et al 2015). In addition, Li et al (2014) determined that South China tectonic evolution is characterized by the alternate appearance of compression and extension based on Cretaceous basin magmatism and paleo-tectonic stress field. There was a compression environment at around 110 Ma.…”
