摘要
<正>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
