Data for: B diffusion, related isotope fractionation and the structural role of B in pegmatitic melts

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. The files contain the diffusion profile data obtained by electron microprobe (D1), femtosecond laser ablation sector field ICP-MS (D2) and femtosecond laser ablation multi collector ICP-MS (D3). D4 shows near infrared spectroscopy data for the calibration of linear molar absorption coefficients. D5 gives all data for solid-state nuclear magnetic resonance experiments.

本研究进行了一项关于高温高压下长石质熔体中B元素自扩散与化学扩散的实验性扩散研究。通过执行名义上干燥和水含量（3.1–3.9 wt % H2O）的实验，评估了水对扩散率的影响。文件包含了通过电子探针（D1）、飞秒激光剥蚀区域场电感耦合等离子体质谱（D2）和飞秒激光剥蚀多道电感耦合等离子体质谱（D3）获得的扩散谱线数据。D4展示了近红外光谱数据，用于线性摩尔吸收系数的校准。D5提供了固态核磁共振实验的所有数据。
