Extended Data Fig. 1: Geochronology of Jack Hills Zircons.
From: Contemporaneous mobile- and stagnant-lid tectonics on the Hadean Earth
Geochronology for Jack Hills detrital zircons from 3 of the 19 zircon mounts analyzed in this study. 1 A: Histogram of 207Pb/206Pb ages from 1-min analyses, “quick ages”. 1B: quick ages vs. 207Pb/206Pb ages from full U/Pb analyses. The 2839 quick ages represent all zircons in three epoxy mounts (ERC-8, -9, −10) showing the age distribution of JH zircons after sorting for low magnetic susceptibility by Frantz and hand-picking. The 125, >95% concordant U-Pb analyses, in addition to those reported earlier12,26, represent the most accurate ages for zircons analyzed in this study.
