摘要：

Zirconium and hafnium contents were determined by radiochemical neutron activation analysis for some basaltic and granitic geological standard rock samples. Our values for Zr and Hf are consistent with the literature values for basaltic samples, but are systematically higher than the literature data, especially for Zr, for granitic samples, though their relative ratios were found to be in good agreement with meteoritic values. The present work suggests that the literature values of Zr and Hf are systematically low for some granitic rock standard samples.
