Correction: Corrigendum: An early geodynamo driven by exsolution of mantle components from Earth’s core

Nature 536, 326–328 (2016); doi:10.1038/nature18594 Some of the analyses (samples X1–2, X1–3, X1–4 and X2–4) reported in this Letter’s Extended Data Table 1 and in the Supplementary Data spreadsheet were previously published in refs 28 and 30. The other analyses are new measurements, as are all measurements of aluminium concentration in the metal we studied.
