Statement

Table S12-13 and S20: Whole-rock analysis was acquired by X-ray fluorescence (XRF), samples were analysed on a PANalytical Axios Advanced XRF spectrometer at the University of Leicester. Table S14-17 and S21-22: Glass major elements and mineral compositions were acquired by Electron Probe Microanalysis (EPMA), samples were analysed on a Cameca SX-100 Electron Probe Micro-Analyzer at the University of Cambridge. An accelerating voltage of 15 kV was used for all analysis. A beam size of 10 µm was used for glass analyses, 5 µm was used for feldspar, 1 µm was used for pyroxene. Currents of between 10 and 100 nA were used. Table S14 and S23: Glass trace elements were acquired by Secondary Ion Mass Spectrometry (SIMS) using a Cameca ims-4f ion probe at the University of Edinburgh.
