Abstract
Plate tectonic processes introduce basaltic crust (as eclogite) into the peridotitic mantle. The proportions of these two sources in mantle melts are poorly understood. Silica-rich melts formed from eclogite react with peridotite, converting it to olívine-free pyroxenite. Partial melts of this hybrid pyroxenite are higher in nickel and silicon but poorer in manganese, calcium, and magnesium than melts of peridotite. Olivine phenocrysts' compositions record these differences and were used to quantify the contributions of pyroxenite-derived melts in mid-ocean ridge basalts (10 to 30%), ocean island and continental basalts (many >60%), and komatiites (20 to 30%). These results imply involvement of 2 to 20% (up to 28%) of recycled crust in mantle melting.

The proportions of these two sources in mantle melts are poorly understood. Silica-rich melts formed from eclogite react with peridotite, converting it to olívine-free pyroxenite. Partial melts of this hybrid pyroxenite are higher in nickel and silicon but poorer in manganese, calcium, and magnesium than melts of peridotite. Olivine phenocrysts' compositions record these differences and were used to quantify the contributions of pyroxenite-derived melts in mid-ocean ridge basalts (10 to 30%), ocean island and continental basalts (many >60%), and komatiites (20 to 30%). These results imply involvement of 2 to 20% (up to 28%) of recycled crust in mantle melting.</EA><CC>222A01; 225B02; 220B03; 001E01F01; 001E01M02; 001E01B03</CC><FD>Recyclage; Croûte océanique; Manteau; Tectonique plaque; Eclogite; Basalte; Zone subduction; Péridotite; Pyroxénite; Fusion partielle; Composition chimique; MORB; OIB; Basalte plateau; Komatiite; Forsterite; Hétérogénéité</FD><FG>Roche métamorphique; Roche volcanique; Roche ignée; Roche ultramafique; Roche plutonique; Basalte tholéïtique; Roche ultrabasique; Olivine; Nésosilicate; Silicate</FG><ED>recycling; oceanic crust; mantle; plate tectonics; eclogite; basalts; subduction zones; peridotites; pyroxenite; partial melting; chemical composition; Mid Ocean Ridge Basalt; ocean-island basalts; flood basalts; komatiite; forsterite; heterogeneity</ED><EG>metamorphic rocks; volcanic rocks; igneous rocks; ultramafics; plutonic rocks; tholeiitic basalt; ultrabasic rocks; olivine; nesosilicates; silicates</EG><SD>Reconversión; Corteza oceánica; Abrigo; Tectónica placas; Eclogita; Basalto; Zona subducto; Peridotitis; Piroxenita; Fusión parcial; MORB; Forsterita; Heterogeneidad</SD><LO>INIST-6040.354000149493670240</LO><ID>07-0241048</ID></server></inist></record>Pour manipuler ce document sous Unix (Dilib)
