Fig. 1: Major- and trace-element partial melt data from our experiments.
From: Deep formation of Earth’s earliest continental crust consistent with subduction

a, N-MORB-normalized plot showing ETT15,20,48,49,50 and trace-element results from our experiments. b, Anorthite–albite–orthoclase ternary diagram classifying our hydrous partial melts as tonalitic51. c–e, Sr/Y–Y (c), La/Nbmn–Gd/Timn (d) and La/Nbmn–Gd/Ybmn (e) diagrams. Fractional crystallization (FC) trends in c–e are calculated using the equation from ref. 52 and distribution coefficients in ref. 53. Some diagrams do not show plagioclase and clinopyroxene FC vectors because the trends are very short. Experimental data >1.6 GPa are partial melts in equilibrium with residual garnets that are generated at pressures higher than those possible in intracrustal environments22,23.
