Extended Data Fig. 5: Plate-motion analysis 0–600 Ma.
From: Hadaean to Palaeoarchaean stagnant-lid tectonics revealed by zircon magnetism
a, Distribution of sites used in plate-motion analysis. Different colours distinguish between assigned plates. b, Representative example of the motion path for a single site with Δλ at the median value (76°) determined using the plate-motion models described in the text. Solid line shows motion path resolved at 1-Myr intervals, black circles show 20-Myr steps. Blue circle, present-day site location; yellow circle, site palaeolocation at 600 Ma; red diamond, location at which the maximum latitudinal displacement is reached. c, Distribution of Δλ from 228 sites located on 66 plates, determined using 1-Myr time steps shown with age of maximum latitudinal distance (Δλ) from present versus angle. d, Distribution of Δλ in 5° bins; red line (and right y axis) shows empirical cumulative distribution of Δλ.
