Plesovice zircon : A new natural reference material for U-Pb and Hf isotopic microanalysis
Jirri Slama,Jirri Slama,Jirri Slama,Jan Košler,Daniel J. Condon,James L. Crowley,Axel Gerdes,John M. Hanchar,Matthew S.A. Horstwood,George A. Morris,Lutz Nasdala,Nicholas Norberg,Urs Schaltegger,Blair Schoene,Michael Tubrett,Martin J. Whitehouse +15 more
TL;DR: The Plesovice zircon as discussed by the authors has a concordant U-Pb age with a weighted mean Pb-206/U-238 date of 337.13 +/- 0.37 Ma (ID-TIMS, 95% confidence limits, including tracer calibration uncertainty).
Journal ArticleDOI
Combined U–Pb and Hf isotope LA-(MC-)ICP-MS analyses of detrital zircons: Comparison with SHRIMP and new constraints for the provenance and age of an Armorican metasediment in Central Germany
Axel Gerdes,Armin Zeh +1 more
TL;DR: Uranium-lead ages obtained by LA-ICP-MS analyses of zircon cores from a high-grade Armorican metasediment from the Mid-German Crystalline Rise, Central Germany, yield results which are identical to, but more precise than those previously obtained by SHRIMP dating.
Journal ArticleDOI
Zircon formation versus zircon alteration — New insights from combined U–Pb and Lu–Hf in-situ LA-ICP-MS analyses, and consequences for the interpretation of Archean zircon from the Central Zone of the Limpopo Belt
Axel Gerdes,Armin Zeh +1 more
TL;DR: In this paper, the combination of U-Pb and Lu-Hf isotope data obtained by laser ablation-inductive coupled plasma-mass spectrometry provides a powerful tool for distinguishing zircon domains grown during several metamorphic or magmatic events from altered domains affected by complete single or multiple Pb-loss.
Journal ArticleDOI
Natural fractionation of 238U/235U
TL;DR: In this article, the authors report variations of the 238U/235U isotope ratio in natural samples (basalts, granites, seawater, corals, black shales, suboxic sediments, ferromanganese crusts/nodules and BIFs) of ∼1.3.
Journal ArticleDOI
Precise and accurate in situ U-Pb dating of zircon with high sample throughput by automated LA-SF-ICP-MS
Dirk Frei,Axel Gerdes +1 more
TL;DR: In this article, an automated method for U-Pb age dating of zircon by single collector laser ablation-magnetic sectorfield-inductively coupled plasma mass spectrometry (LA-SF-ICP-MS) is presented.
