Numerical simulation of the temporal evolution of residual liquid composition due to undercooling crystallization of HK-basalt from Stromboli. The temperature decreases from 1200°C to 1100°C with a cooling rate of 1 °C/h and then the temperature is kept constant at 1100°C for 12 hours (please note the video advances with different speeds during the two phases).
On the left panel, the evolution of the composition is plotted with a thin black line during the cooling phase and with a thick black line during the subsequent 12 hours.
Red and green lines represent the isotherms corresponding to the final temperature and the blue line is the cotectic curve.
The numerical model is based on the method of moments technique to track the temporal evolution of the crystal size distribution.
On the right panel, the temporal evolution of the CSDs is shown.
