The analytical results are from LAM-ICP-MS analyses of trace and minor element concentrations in run products, the experimental starting glass (UT-70489), and the USGS standard BCR-2 (which was analysed at regular intervals as an unknown during analyses of run products). These data were used to calculate the fluid/melt and fluid/mineral D values presented in Table 3 and Figs. 3-6 of the main text, as well as to check on the accuracy of results. The photos are back-scattered electron images which show the distributions and textural characteristics of run products in capsules at the finish of experiments. The images have been selected to illustrate the effects of varying pressure (from 1.0 to 4.0 GPa) on run products and the mutual solubilities of hydrous fluids and melts. Both the LAM-ICP-MS analyses and back-scattered electron images were obtained during the course of this study using instrumentation at the GEMOC Analytical Facility of Macquarie University, Australia (see main text). The analytical data are presented as two tables in one file (-ts1to2.pdf). The photographic images are contained in a second file which has twelve figures (-fs1to12.wds).
