Journal ArticleDOI
The application of laser ablation-inductively coupled plasma-mass spectrometry to in situ U–Pb zircon geochronology
TL;DR: In this paper, a laser ablation-inductively coupled plasma-mass spectrometer (LA-ICP-MS) was used for in situ U-Pb zircon geochronology.
Journal ArticleDOI
The Hf isotope composition of cratonic mantle: LAM-MC-ICPMS analysis of zircon megacrysts in kimberlites
William L. Griffin,William L. Griffin,Norman J. Pearson,Elena Belousova,Simon E. Jackson,E. van Achterbergh,Suzanne Y. O'Reilly,S. R. Shee +7 more
TL;DR: In this article, the isotopic composition of Hf has been measured in 124 mantle-derived zircon megacrysts from African, Siberian and Australian kimberlites, using a laser-ablation microprobe (LAM) and a multi-collector ICPMS.
Journal ArticleDOI
Zircon chemistry and magma mixing, SE China: In-situ analysis of Hf isotopes, Tonglu and Pingtan igneous complexes
William L. Griffin,William L. Griffin,Xiang Wang,Xiang Wang,Simon E. Jackson,Norman J. Pearson,Suzanne Y. O'Reilly,Xisheng Xu,Xisheng Xu,Xinmin Zhou +9 more
TL;DR: In this article, in-situ LAM-MC-ICPMS microanalysis shows large variations in 176Hf/177Hf (up to 15 eHf units) between zircons of different growth stages within a single rock, and between zones within single zircon grains, suggesting that each of the observed magmas in both complexes developed through hybridisation of ≥2 magmas with different sources.
Journal ArticleDOI
Archean crustal evolution in the northern Yilgarn Craton: U–Pb and Hf-isotope evidence from detrital zircons
William L. Griffin,William L. Griffin,Elena Belousova,S. R. Shee,Norman J. Pearson,Suzanne Y. O'Reilly +5 more
TL;DR: Whitaker et al. as mentioned in this paper integrated U-Pb dating, Hf-isotope analysis and trace-element analysis to detrital zircon populations offers a rapid means of assessing the geochronology and crustal evolution history of different terranes within a composite craton.
Journal ArticleDOI
The growth of the continental crust: Constraints from zircon Hf-isotope data
Elena Belousova,Y. A. Kostitsyn,William L. Griffin,Graham Begg,Suzanne Y. O'Reilly,Norman J. Pearson +5 more
TL;DR: In this paper, the authors introduce a new approach to quantitatively estimate the proportion of juvenile material added to the crust at any given time during its evolution, which is then used to model the crustal growth rate over the 4.56-Ga of Earth's history.
