| 6 | ε-Neodymium (0) | ε-Nd(0) | Martin, Ellen E | Calculated | e-Nd (0) = [143Nd/144Ndmeasured/143Nd/144NdCHUR -1] x 104, where 143Nd/144NdCHUR = 0.512638 | |
| 7 | ε-Neodymium (T) | ε-Nd(T) | Martin, Ellen E | Calculated | e-Nd (T) was calculated using a value of 147Sm/144Nd = 0.110 for detrtital fractions and a value of 0.125 for HH fractions | |
| 8 | ε-Neodymium, standard deviation | ε-Nd std dev | ± | Martin, Ellen E | Calculated | Internal errors are 2SE. A 2s external error of +/-0.000014 (or 0.3 e-Nd units) is based on replicate runs of JNdi-1 |
