Supplementary figure captions 1 2 Supplementary Figure 1. ACFN phase diagram for the metabasites of the Mérida Ophiolite. 3 Projection from phases quartz, ilmenite, apatite and H 2 O fluid and the exchange vectors 4 NaSi(CaAl) -1 , MnFe -1 and MgFe -1 . Bulk compositions of the common metagabbros 5 (green diamonds) and garnet amphibolites (red circles) are shown, as well as end- 6 members of solid solutions of interest. The phase relations are schematic. 7 8 Supplementary Figure 2. Isopleths calculated for the pseudosection of sample 117350. a), 9 b), c) and d), represent X Grs , X Alm , X Sps and X Prp contents in garnet, respectively. e) X Ab 10 content in plagioclase. f) Modal garnet content and possible paths for garnet growth. 11 12 13 14 15 16 6XSSOHPHQWDU\ PDWHULDO IRU &KDSWHU
