a, Representative scanning electron microscope (SEM) image of sample OJPgw18 that used 1187-8 starting material with 2.0 wt% water and was run for 24 h at 975 °C and 1.6 GPa (see Supplementary Table 2 for run conditions). b, SEM image of a large garnet crystal in OJPgw10 that was run at 2.0 GPa and 925 °C. c, Sample OJP4gw4, unstable garnet (gnt) that has broken down into plagioclase (plag), orthopyroxene (opx) and titanomagnetite after being run first for 24 h at 2.0 GPa and 950 °C and then for 48 h at 1.4 GPa and 1,000 °C.
