Linking South China to North India from the late Tonian to Ediacaran: Constraints from the Cathaysia Block

A Consistently High‐Latitude South China From 820 to 780 Ma: Implications for Exclusion From Rodinia and the Feasibility of Large‐Scale True Polar Wander

“…Tonian volcanism in northwest India shares geochemical characteristics with arc magmatism in the Panxi-Hannan Belt (Ashwal et al, 2013;Cawood et al, 2017), which has been interpreted as the result of a continuous subduction zone along northwestern Yangtze and western India and consistent with a connection between western South China and northwestern India. Detrital zircon spectra of Cryogenian sediments in South China also appear similar to that observed in northwestern India, further supporting this connection (Cawood et al, 2017;Qi et al, 2020). However, the ca.…”

The origin of the ultrahigh-pressure Tso Morari complex, NW Himalaya: implication for early Paleozoic rifting

“…Coupled with geochemical results in this study, we posit that the Early Paleozoic rifting after the Neoproterozoic Pan-African orogeny produced the protoliths of the TMC. Recently, a close relationship between North India and South China during the Neoproterozoic to Early Paleozoic has been discussed (Qi et al 2020; Imayama et al 2023), and the Early Paleozoic rifting in NW India led to the separation of South China from North India (Fig. 5, Imayama et al 2023).…”

New Paleomagnetic Insights Into the Neoproterozoic Connection Between South China and India and Their Position in Rodinia

“…Similar age distributions and Hf‐O isotopes features of detrital zircons from the Tonian strata between the Yangzte block and northwestern India demonstrate that they shared a common provenance (Wang et al., 2021). The Cathysia block also shows a consistent detrital zircon spectrum of the Tonian and Ediacaran sequences with the Greater Himalaya region (Qi et al., 2020; Yu et al., 2008). Coeval igneous rocks in the western to northwestern SCC, northwestern India, Seychelles, and Madagascar are considered to have formed in a similar arc‐related setting (Ashwal et al., 2002, 2013; Dong et al., 2012; Zhou et al., 2006).…”
