Fig. 6

Back-scattered electron (BSE) images of representative garnet from samples a MR142 and b MR113 together with their chemical profiles based on electron microprobe analyses (see also Online Resources 3 and 4). Star symbols to the right of the profiles represent analyses of a smaller, un-zoned garnet population present in both samples. The zoning profile for sample MR142 is typical for garnet (almandine) formed under low-amphibolite-facies PT conditions and shows a prograde Mn-bell profile due to the substitution of Fe for Mn. Sample MR113 exhibits an even less developed zoning pattern, the dashed circle marks the rotated core of sample MR113
