Triassic southeastward subduction of North China Block to South China Block: Insights from new geological, geophysical and geochemical data

Earth-Science Reviews, 2017
Abstract Lithospheric subduction prior to the assembly of the South China and North China blocks is traditionally considered to be directed northward. However, some critical geological and geochemical data cannot be reconciled with this northward subduction.

Mantle Upwelling Beneath the Cathaysia Block, South China

Tectonics, 2021
AbstractA large low‐velocity anomaly (LLVA) beneath the Cathaysia Block in South China that may be associated with mantle upwelling was revealed by seismic tomography. However, seismological and geological studies indicate that ascending mantle must have a higher temperature than the surrounding mantle, and a low‐velocity anomaly alone is not ...

Denudation history of South China block and sediment supply to northern margin of the South China Sea

Journal of Earth Science, 2009
On the basis of apatite fission track (AFT) analyses, this article aims to provide a quantitative overview of Cenozoic morphotectonic evolution and sediment supply to the northern margin of the South China Sea (SCS). Seventeen granite samples were collected from the coast to the inland of the South China block.

Paleogeography of the North and South China blocks during the Cambrian

Journal of Geodynamics, 1985
Abstract Paleomagnetic results demonstrate that during the Cambrian the South China block was close to the equator. We suggest that it was adjacent to North Australia. This reconstruction juxtaposes Cambrian marine basins in South China and Australia, explaining the affinity between Cambrian trilobites from the two areas, as well as the existence of ...

Early Mesozoic intracontinental deformation in the eastern North China Block: Implication for an indentation model of North China to South China blocks

Geological Journal, 2017
The Qinling‐Dabie‐Sulu Orogen was formed by the collision of the North and South China blocks during the Indosinian Period. The intracontinental deformation was subsequently developed during the Late Triassic to Early Jurassic in the northeastern, eastern, and southeastern parts of eastern North China Block with different structural patterns.

Petrogenesis of the Early-Middle Triassic high-Mg andesitic rocks in the southern margin of the South China Block: Implications for the convergence between the South China and Indochina Blocks

Journal of Asian Earth Sciences, 2022
Abstract Questions remain about whether the volcanic rocks and spatially associated mafic to intermediate intrusions in the Funing area, Southwestern China, are part of Emeishan large igneous province (ELIP) and formed in a plume-related extensional setting.

Discussion on the Neoproterozoic glaciations in the South China Block and their related paleolatitudes

Science Bulletin, 2009
The Kaigas, Sturtian, Marinoan, and Gaskiers glaciations are widely recognized in Neoproterozoic. However, in the South China Block only the Jiangkou (Sturtian) and Nantuo (Marinoan) are symbolized by sedimentary records. The Kaigas, recorded by isotopic and chemical proxies, exhibited likely the nature of cold paleoclimate with local mountain ...

Shear-wave splitting in the southeast of Cathaysia block, South China

Journal of Seismology, 2008
This study is focused on Fujing Province in China, southeast of Cathaysia block (SECB). The present work benefits from the data provided by the Fujian Seismic Network (FJSN) to study the seismic anisotropy in the crust. By means of a systematic analysis and adequate software package, we examine shear-wave splitting from data recorded at ten FJSN ...

The stationary Cretaceous paleomagnetic pole of Sichuan (South China Block)

Tectonics, 1991
Upper Jurassic to lower Tertiary sites have been sampled from three localities, separated by up to 150 km, in the Sichuan Basin (∼30°N, 103°E) of the South China Block. Each locality has at least one stability test, but none alone gives a fully reliable result.
