A Correlation Approach to the Common Pb Contribution to 207 Pb/206Pb Ratios Obtained by the Zircon Evaporation Technique

Description
Summary:P5; An approach is recommended for the correction of common Pb contribution to 207Pb/206Pb ages obtained by the zircon evaporation technique. A comparison with that by Cocherie et al. (1992) shows that two approaches yield similar results in the 207Pb */206Pb * ratios. But when using the new approach, only two errors of the measured 204Pb/206Pb and 207Pb/206Pb ratios are introduced to the calculated 207Pb */206Pb * ratios.
