Extended Data Fig. 2

Equilibrium phase assemblage is shown for 1,000–2,000 °C, 20–60 kbar for KR4003 (a), Ext1 (b), Ext2 (c) and Ext2.5 (d). Each subsequent composition is more refractory than the last, reflected in the increasing simplicity of the phase assemblages and higher liquidus temperatures.
