Coupled 142Nd-143Nd Isotopic Evidence for Hadean Mantle Dynamics

The oldest rocks - 3.85 billion years old - from southwest Greenland have coupled neodymium-142 excesses (from decay of now-extinct samarium-146; half-life, 103 million years) and neodymium-143 excesses (from decay of samarium-147; half-life, 106 billion
