Evolution of interior temperature of an Earth-like planet as it cools from fully molten to fully solid (Case 3v). Global melt fractionϕ_g is given in brackets after the time in Myr. Surface and core-mantle boundary are at 0 and 135 GPa, respectively, and the mantle is initially superliquidus (0 Myr). Grey shaded region shows where the melt and solid phase coexist and is bounded by the liquidus above and the solidus below. Dashed lines denote pure solid or melt, and solid lines show where solid and melt coexist.
