Mineral assemblages and fluid compositions along the free sinking stage (t = 15 Myr) from18 for sedimentary and mafic composition of the AC. (a,b) Mineral assemblages’ evolution for sedimentary (GLOSS-garnet-bearing mica-schist) and mafic (MORB-blueschist) compositions of the AC. (c,d) MORB-normalized multi-element diagrams of fluids produced from sedimentary and mafic compositions of the AC.
