(1999)This paper presents a Hf and Zr chemical purification method and calibration procedure used to measure Zr/Hf ratios in terrestrial and extraterrestrial rocks by isotope dilution mass spectrometry with a mixed 96Zr-179Hf ...
-
(2000)In order to evaluate the widely accepted assumption that Zr/Hf ratios are uniform and chondritic (i.e. equal to 36.6) in terrestrial rocks [Jochum et al., Geochim. Cosmochim. Acta 50 (1986) 1173-1183], precise Zr/Hf ...
-
(1997)An analytical method for high-precision measurement of zirconium isotope ratios using a Sector thermal ionization mass spectrometer (TIMS) is reported. The chemical separation procedure of Zr has been refined by employing ...
-
(2000)The presence of Zr isotope anomalies in the early solar system is demonstrated with the identification of 92Zr excesses and 96Zr deficits in several chondrites and the CAI Allende inclusions. The isotopic composition of ...
