TLDR
The South China craton was formed at the end of the Mesoproterozoic by Rodinia and occupied a position adjacent to Western Australia and northern India in the early NeoproTERozoic as discussed by the authors.Abstract:
From the formation of Rodinia at the end of the Mesoproterozoic to the commencement of Pangea breakup at the end of the Paleozoic, the South China craton fi rst formed and then occupied a position adjacent to Western Australia and northern India. Early Neoproterozoic suprasubduction zone magmatic arc-backarc assemblages in the craton range in age from ca. 1000 Ma to 820 Ma and display a sequential northwest decrease in age. These relations suggest formation and closure of arc systems through southeast-directed subduction, resulting in progressive northwestward accretion onto the periphery of an already assembled Rodinia. Siliciclastic units within an early Paleozoic succession that transgresses across the craton were derived from the southeast and include detritus from beyond the current limits of the craton. Detrital zircon age spectra require an East Gondwana source and are very similar to the Tethyan Himalaya and younger Paleozoic successions from Western Australia, suggesting derivation from a common source and by inference accumulation in linked basins along the northern margin of Gondwana, a situation that continued until rifting and breakup of the craton in the late Paleozoic.read more

Jiangnan Orogen in South China: Developing from divergent double subduction
TL;DR: The Jiangnan Orogen is considered as a continent-continent collisional belt resulting from the closure of a Meso-Neoproterozoic ocean separating the southeastern margin of the Yangtze Block from the northwestern boundary of the Cathaysia Block.

Reconstructing South China in Phanerozoic and Precambrian supercontinents
TL;DR: The history of the South China Craton and the constituent Yangtze and Cathaysia blocks are directly linked to Earth's Phanerozoic and Precambrian record of supercontinent assembly and dispersal.

Early Paleozoic and Early Mesozoic intraplate tectonic and magmatic events in the Cathaysia Block, South China
TL;DR: In this article, a geodynamic framework of the South China Craton in the Early Paleozoic and Early Mesozoic has been modeled as developing through either oceanic convergence or intracontinental settings, based on an integrated structural, geochemical, zircon U-Pb and Hf isotopic and mica 40Ar/39Ar geochronologic study.

Review of global 2.1-1.8 Ga orogens: implications for a pre-Rodinia supercontinent
TL;DR: The existence of a supercontinent existing before Rodinia, referred to herein as Columbia, a name recently proposed by Rogers and Santosh [Gondwana Res. 5 (2002) 5] for a Paleo-Mesoproterozoic super-continent, was confirmed by available lithostratigraphic, tectonothermal, geochronological and paleomagnetic data as mentioned in this paper.

TL;DR: In this article, the authors proposed a model for the origin of the 2.55-2.50-Ga metamorphic pulse in the North China Craton (NCC), which is interpreted as a major phase of juvenile crustal growth in the craton.
