Zirconium and hafnium in meteorites
Journal Article

· Earth and Planetary Science Letters
The abundances of zirconium and hafnium have been determined in nine stony meteorites by a new, precise neutronactivation technique. The Zr/W abundance ratios for the chondrites vary in a rather narrow rarge, consistent with previously published observations. Replicate analyses of new, carefully selected clean interior samples of the C1 chondrite Orgneil yield mean zirconium and hafnium abundances of 5.2 and 0.10 ppM, respectively. These abundances are lower than reported earlier for two C1 chondrite samples which may have suffered contamination. The new C1 zirconium and hafnium abundances are in closer agreement with predictions based on theories of nucleosynthesis than the earlier data.
