Supplemental Material: Buoyancy of volatile-rich kimberlite melts, magma ascent, and xenolith transport

Description of the methodology along with additional supporting data. These include the starting melt composition (Table S1) and the rationale for selecting the Jericho kimberlite; the procedure for calculating atomic self-diffusion coefficients and their comparison with literature values (Fig. S2); the fitting of a third-order Birch-Murnaghan equation of state to melt density data (Figs. S3 and S4); the interpolation method applied to determine the carbon content required for neutral buoyancy (Fig. S5); and the calculation of melt transport capacity. A discussion of the model assumptions and limitations is also provided.
