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.Supplement to: Kenny, Gavin; Schmieder, Martin; Whitehouse, Martin J; Nemchin, Alexander A; Morales, Luiz F G; Buchner, Elmar; Bellucci, Jeremy J; Snape, Joshua F (2019): A new U-Pb age for shock-recrystallised zircon from the Lappajärvi impact crater, Finland, and implications for the accurate dating of impact events.
