Stable isotope geochemistry of ultrahigh pressure metamorphic rocks from the Dabie–Sulu orogen in China: implications for geodynamics and fluid regime
TL;DR: In this article, a fried ice cream model was proposed to explain the rapid processes of both plate subduction and exhumation, with a short residence time of the UHP slab at mantle depths.
Journal ArticleDOI
Oxygen Isotopes in Zircon
TL;DR: A large number of studies have shown that non-metamict zircons preserve their δ18O value from the time of crystallization; hence oxygen isotope ratio can be correlated with age (U-Pb) or trace element composition as discussed by the authors.

Contrasting zircon Hf and O isotopes in the two episodes of Neoproterozoic granitoids in South China: Implications for growth and reworking of continental crust
Yong-Fei Zheng,Yong-Fei Zheng,Shao-Bing Zhang,Zi-Fu Zhao,Yuan-Bao Wu,Yuan-Bao Wu,Xian-Hua Li,Zheng-Xiang Li,Fu-Yuan Wu +8 more
TL;DR: In this article, a combined study of Hf and O isotopes in zircons from Neoproterozoic granitoids in South China provides evidence for growth and reworking of juvenile and ancient crusts with different styles of water-rock interactions along rift tectonic zones.

Stable isotope geochemistry of clay minerals; The story of sloppy, sticky, lumpy and tough, Cairns-Smith (1971)
S. M. F. Sheppard,H. A. Gilg +1 more
TL;DR: The equilibrium H- and O-isotope fractionation of clays can be approximated by the following equations which are based on experimental, empirical and/or theoretical data.

Rift melting of juvenile arc-derived crust: Geochemical evidence from Neoproterozoic volcanic and granitic rocks in the Jiangnan Orogen, South China
TL;DR: In this article, a combined study of zircon U-Pb and Lu-Hf isotopes, mineral O isotope, whole-rock elements and Sr-Nd isotopes was carried out for Neoproterozoic volcanics and granites from the eastern part of the Jiangnan Orogen in South China.

Calculation of Equilibrium Constants for Isotopic Exchange Reactions
TL;DR: In this article, it was pointed out that the possibility of chemical separation of isotopes is a quantum effect and that the difference in the free energies of two isotopic molecules can be directly calculated.

Oxygen isotopic fractionation in the system quartz-albite-anorthite-water
TL;DR: Oxygen isotopic fractionations have been determined between quartz and water, albite and water and anorthite and water at temperatures from 300 to 825°C, and pressures from 15 to 25 kbar as mentioned in this paper.
