Effects of decarbonation on elemental behaviors during subduction-zone metamorphism: Evidence from a titanite-rich contact between eclogite-facies marble and omphacitite
Omphacite and garnet indicate marble has experienced eclogite-facies metamorphism. Effects of carbonate subduction on element behaviors during SZM are discussed. Carbonate subduction is crucial for arc magmatism and mantle isotopic heterogeneity.
