Data for: B diffusion, related isotope fractionation and the structural role of B in pegmatitic melts
Description
We performed an experimental diffusion study investigating the self- and chemical diffusion of B in a pegmatitic melt under high temperature and pressure. The effect of water on the diffusivity was assessed by conducting nominally dry and water-bearing (3.1–3.9 wt % H2O) experiments. S1 shows images of all the diffusion couples with the positions of measurements and the inferred interfaces. The other files are the diffusion profile data obtained by electron microprobe (S2), femtosecond laser ablation sector field ICP-MS (S3) and femtosecond laser ablation multi collector ICP-MS (S4). S5 shows near infrared spectroscopy data for the calibration of linear molar absorption coefficients. S6 gives all data for solid-state nuclear magnetic resonance experiments.
