Fig. 4: Growth rate of clinopyroxene crystals as a function of the experimental time.

a Plot showing the evolution of growth rates of 5 clinopyroxene crystals through time during the experiment Exp-A at ∆T = 10 °C (euhedral crystal shapes are promoted by interface-controlled growth) and at ∆T = 30 °C (dendritic crystal shapes are promoted by diffusion-limited growth). Light grey shading represents ∆T = 10 °C, dark grey shading represents ∆T = 30 °C. b Plot showing the evolution of growth rates of 5 clinopyroxene crystals through time during the experiment Exp-B at ∆T = 20 °C (euhedral crystal shapes are promoted by interface-controlled growth) and at ∆T = 50 °C (dendritic crystal shapes are promoted by diffusion-limited growth). Light grey shading represents ∆T = 20 °C, dark grey shading represents ∆T = 50 °C. The undercoolings (∆T) investigated are calculated with respect to the clinopyroxene liquidus.
