Phanerozoic tectonics of the South China Block: Key observations and controversies
TL;DR: In this article, the authors presented an overview of key geological observations in the South China Block with respect to its Phanerozoic tectonics, and proposed a geodynamic model for the Mesozoic evolution of the SCB, which is characterized by strong thrusting/transpression, anatexic granitic magmatism, high-grade metamorphism and the poor involvement of the juvenile mantle derived rocks.

Tectonic setting of the South China Block in the early Paleozoic: Resolving intracontinental and ocean closure models from detrital zircon U‐Pb geochronology
Yuejun Wang,Feifei Zhang,Weiming Fan,Guowei Zhang,Shiyue Chen,Peter A. Cawood,Peter A. Cawood,Aimei Zhang +7 more
TL;DR: Zircon U-Pb geochronological data on over 900 zircon grains for Cambrian to Silurian sandstone samples from the South China Block constrain the pre-Devonian tectonic setting of, and the interrelationships between, the constituent Cathaysia and Yangtze blocks as discussed by the authors.

Late Cretaceous-Early Palaeogene tectonic development of SE Asia
TL;DR: In this paper, the authors propose that the origin and timing of termination of subduction has been explained by collision of a large Luconia continental fragment either during the Late Cretaceous or Palaeogene.

Kwangsian crustal anatexis within the eastern South China Block: Geochemical, zircon U-Pb geochronological and Hf isotopic fingerprints from the gneissoid granites of Wugong and Wuyi-Yunkai Domains
Yuejun Wang,Yuejun Wang,Aimei Zhang,Weiming Fan,Guochun Zhao,Guowei Zhang,Yuzhi Zhang,Feifei Zhang,Sanzhong Li +8 more
TL;DR: In this article, a model of two-stage crustal anatexis is proposed for the Kwangsian granitic magma in the eastern South China Block, with the formation of 460-430-Ma granite through the breakdown of hydrous minerals under the condition of the doubly thickened crust, and the generation of the 430-400 -Ma granite accompanying promoted melting along a path of isothermal decompression due to the increasing thermal weakening for the collapse of the thickening crust.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.

TL;DR: The IUGS Subcommission on Geochronology (FOOTNOTE 4) as discussed by the authors recommended the adoption of a standard set of decay constants and isotopic abundances in isotope geology.

Approximation of terrestrial lead isotope evolution by a two-stage model
J.S. Stacey,Jan Kramers +1 more
TL;DR: In this paper, a two-stage model for terrestrial lead isotope evolution is proposed, which permits the age of the earth to be that of the meteorite system and also yields good model ages for samples of all ages.

Trace element and isotopic effects of combined wallrock assimilation and fractional crystallization
TL;DR: In this paper, the mass assimilation rate is an arbitrary fraction(r) of the fractional crystallization rate, where r < 1 is a combination of zone refining and fractional scaling.

A large-scale isotope anomaly in the Southern Hemisphere mantle
TL;DR: The authors showed that the isotopic mantle anomaly is globe-encircling in extent, centred on latitude 30° S. They also showed that this mantle anomaly has been in existence for billions of years and placed severe constraints on mantle convection models.
