Error in Temora reference zircon calibration was 0.63% & 0.52% for the analytical session (not included in above errors but required when comparing 206Pb/238U data from different mounts). f206 % denotes the percentage of 206Pb that is common Pb. For areas older than ~800 Ma correction for common Pb made using the measured 204Pb/206Pb ratio. For areas younger than ~800 Ma correction for common Pb made using the measured 238U/206Pb and 207Pb/206Pb ratios following Tera and Wasserburg (1972) as outlined in Williams (1998).
