Table S.1: Photomicrograph image analysis was carried out using the program JMicroVision. Table S.2: Energy-dispersive X-ray spectroscopy (EDS) was used to examine phase assemblages. EDS was carried out using an FEI Quanta FEG-SEM, with a 20kV and ~5nA beam, at the University of Oxford. 6 EDS maps were constructed as shown below (using a pixel size of 0.25μm), and the proportion of the olivine phase was calculated in each of these. Supplementary Tables A.1-A.4: Electron probe micro analysis (EPMA) of minerals and glass. EPMA was carried out using a Cameca SXFive FEG-electron microprobe (EPMA), at the University of Oxford, and a JEOL 8600 EPMA, at the University of Oxford. Mineral analyses were collected using a 15 kV, 10 nA, 10 μm defocussed spot electron beam. Matrix glass analyses were collected using 6 nA beam.
