Extended Data Fig. 4: BGS and JH zircon palaeointensity values versus time.
From: Hadaean to Palaeoarchaean stagnant-lid tectonics revealed by zircon magnetism
a, BGS palaeointensity data (green circles) and JH palaeointensity data (yellow circles), shown with Welch’s t-test P-value (red curve; see ‘Statistical analysis of BGS and JH zircon palaeointensity data’ section in Methods). b, JH zircon palaeointensity values (Tarduno et al.6,7) with 100-Myr moving-window average. c, BGS zircon palaeointensity values shown with data of a. d, Residuals of JH palaeointensity values relative to model (JH 100-Myr moving-window average). e, Residuals of BGS palaeointensity values relative to model (JH 100-Myr moving-window average). f, Empirical cumulative distribution function (ECDF) plot of JH and BGS residuals.
