Cu‐Isotope Evidence for Subduction Modification of Lithospheric Mantle

Cu‐Isotope Evidence for Subduction Modification of Lithospheric Mantle

Abstract Ultramafic xenoliths from southeastern Arizona, USA, provide evidence for Cu‐isotope heterogeneity in the lithospheric mantle. We report new data on Type I (Cr‐, Mg‐rich) peridotites, but also the first Cu‐isotope data for Fe‐Ti‐Al‐rich Type II pyroxenite (±amphibole) xenoliths. Whole rock...
