Article Title: Porosity evolution of mafic crystal mush during reactive flow
doi: 10.1038/s41467-023-38136-x
Figure Lengend Snippet: Comparison of volumetric flux calculations for porous flow ( A ) and channelised melt flow ( B ) demonstrate that channelised melt flow—with channel radii between 10 and 30 cm—can match the volumetric flux of melt through a crystal mush system 1–3 km in radius with a porosity (Φ) between 0.1 and 0.4. Volumetric flux calculations are performed using the equations displayed in the “Methods” section, with phase densities taken from the alphaMELTS for MATLAB fractional crystallisation model at 1180 °C and the mush density calculated using the modal proportions used in scenarios 1 and 2 (ol 5 :plag 55 :cpx 40 ). The viscosity of the melt phase is calculated in the Python3 tool Thermobar using the melt viscosity model of Giordano et al. at 1180 °C and the liquid composition from alphaMELTS for MATLAB.
Article Snippet: The calculations are performed using a range of different channel radii, other parameters are taken from alphaMELTS for MATLAB (that is, the density of the different phases) with the exception of the melt viscosity , (Fig. ).
