A nucleosynthetic origin for the Earth’s anomalous (142)Nd composition

A long-standing paradigm assumes that the chemical and isotopic composition of many elements in the bulk silicate Earth are the same as in chondrites1–4. However, the accessible Earth has a greater (142)Nd/(144)Nd than chondrites. Because (142)Nd is the decay product of now-extinct (146)Sm (t(1/2)=...
