Journal ArticleDOI
The Lu–Hf and Sm–Nd isotopic composition of CHUR: Constraints from unequilibrated chondrites and implications for the bulk composition of terrestrial planets
TL;DR: In this paper, the Lutetium-Hafnium radiogenic isotopic system is used as a chronometer and tracer of planetary evolution, and the Lu-Hf system parameters need to be more tightly constrained, in particular the LuHf isotopic composition of the chondritic uniform reservoir and, by extension, the bulk silicate Earth.
Journal ArticleDOI
The decay constant of 176Lu determined from Lu-Hf and U-Pb isotope systematics of terrestrial Precambrian high-temperature mafic intrusions
TL;DR: In this paper, a cross-calibration of U-Pb and Lu-Hf isotopic systems on mineral fractions from the Proterozoic Karlshamn and Sorkka dolerites in Sweden and Finland is presented.
Journal ArticleDOI
Relationships between Lu–Hf and Sm–Nd isotopic systems in the global sedimentary system
TL;DR: In this paper, the authors report new Hf (and Nd) data for more than 100 sedimentary samples, recent to Archean in age, from a wide range of depositional environments.
Journal ArticleDOI
The isotopic composition of Yb and the precise and accurate determination of Lu concentrations and Lu/Hf ratios by isotope dilution using MC-ICPMS
TL;DR: In this article, the authors report Yb isotopic data for the purpose of accurately correcting measurements of Lu and Lu/Hf ratios during Multicollector Inductively Coupled Plasma Mass Spectrometer (MC-ICPMS) analysis.
Journal ArticleDOI
Behavior of hafnium and neodymium isotopes in the crust: Constraints from Precambrian crustally derived granites
TL;DR: This article determined the hafnium and neodymium isotopic compositions of thirty-two Precambrian granites and rhyolites from diverse suites of crustally derived magmatic suites.
