Therefore, positive numbers correspond to normal discordance and negative numbers correspond to reverse discordance. ** % of common ²⁰⁶Pb in measured ²⁰⁶Pb, estimated from measured ²⁰⁴Pb, assuming present-day Stacey and Kramers (1975) common Pb. Figures lagged with # indicate that no correction has been applied because ²⁰⁴Pb counts were insignificant.
