Fig. 2: Crystallisation of a hydrous trachybasaltic melt through time during single-step cooling experiments at 10 MPa.

a–c Volume renderings show clinopyroxene crystallisation through time during the experiment Exp-A at 1150 °C and ∆T = 10 °C. d–f Volume renderings show clinopyroxene crystallisation through time during the experiment Exp-A at 1130 °C and ∆T = 30 °C. g–i Volume renderings show clinopyroxene crystallisation through time during the experiment Exp-B at 1140 °C and ∆T = 20 °C. j–l Volume renderings show clinopyroxene crystallisation through time during the experiment Exp-B at 1110 °C and ∆T = 50 °C. a–l The undercoolings (∆T) investigated are calculated with respect to the clinopyroxene liquidus. The time in yellow reported in each panel indicates the time passed from the beginning of the experiment.
