Copper isotope fractionation in mantle processes

摘要：

The Earth”s mantle is heterogeneous in elemental and isotopic compositions,which has been ascribed to crustal recycling and mantle processes,such as mantle melting,melt percolation,and metasomatism.Stable(e.g.,C,O,Li,Fe,Mg,Ca) and radiogenic isotopes(e.g.,Sr,Nd,Pb,Hf,Os) have been frequently used to identify recycled crustal components and characterize mantle processes mentioned above.Copper isotope measurements of mantle-derived magmas(e.g.,basalts) as well as orogenic and xenolith peridotites have revealed that the Earth”s mantle has highly variable Cu isotopic compositions with δ65Cu(relative to NIST 976) ranging from-0.68 to 1.82‰(Liu et al.,2015;Savage et al.,2014,2015).
