Formulae are derived for the correlation of errors in the most used lead-lead and uranium-lead diagrams. It is emphasized that with the usual measurement schemes, error correlation is high in the conventional diagrams. An inverse lead-lead diagram is described in which, by proper choice of the measurement scheme, there is no correlation between errors. This advantage is gained whilst maintaining the use of a measurement scheme which optimises the precision of the lead isotope measurements.
