Extended Data Fig. 7: Subduction of carbonate-rich crustal rocks through time.
From: Carbonate-rich crust subduction drives the deep carbon and chlorine cycles

a, Schematic illustration showing subduction of carbonate-rich crustal rocks and replenishment of carbon and/or chlorine to cratonic mantle roots and deep sources of HIMU-type ocean island basalts (OIBs). Stability of carbonate and chloride during subduction of carbonate-rich crustal rocks influenced by the infiltration of Cl-rich fluid in the cold (b), warm (c) and hot (d) subduction regimes.
