Comment: Hf-isotope heterogeneity in zircon 91500
TL;DR: A database of >600 analyses of the zircon “standard” Harvard 91500 shows considerable heterogeneity in 176 Hf/ 177 Hf; the distribution is essentially bimodal with major peaks at 0.282284 −22 and 0.2330 −29 (2σ) as mentioned in this paper.
Journal ArticleDOI
U–Pb ages and source composition by Hf-isotope and trace-element analysis of detrital zircons in Permian sandstone and modern sand from southwestern Australia and a review of the paleogeographical and denudational history of the Yilgarn Craton
TL;DR: In this paper, detrital zircons from the Permian Collie Coal Measures and modern sands on the northern part of the Albany Province have been analysed for U-Pb ages by a laser ablation microprobe-inductively coupled plasma mass spectrometer (LAM-ICPMS).
Journal ArticleDOI
Pan-Gondwanaland detrital zircons from Australia analysed for Hf-isotopes and trace elements reflect an ice-covered Antarctic provenance of 700–500 Ma age, TDM of 2.0–1.0 Ga, and alkaline affinity
TL;DR: In this paper, the authors used the U-Pb SHRIMP method to extract zircons from the Middle Triassic Hawkesbury Sandstone and four Neogene beach sands from Eneabba, 450 km north of the Leeuwin Complex.

Gamburtsev Subglacial Mountains provenance of Permian–Triassic sandstones in the Prince Charles Mountains and offshore Prydz Bay: Integrated U–Pb and TDM ages and host-rock affinity from detrital zircons
John J Veevers,Ayesha Saeed +1 more
TL;DR: In this paper, detrital zircons were analyzed for U-Pb ages, Hf-isotope compositions, and trace elements to determine the age, rock type and source of the host magma, and "crustal" model age (TDMC).
