| 5 | Neodymium-143/Neodymium-144 ratio | 143Nd/144Nd | Martin, Ellen E | Multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) | ||
| 6 | Neodymium-143/Neodymium-144 ratio, error | 143Nd/144Nd e | ± | Martin, Ellen E | Multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS) | Two standard errors of the mean (2SE) are listed and have been used for quality control, such that values with errors greater than 0.000024 have been excluded. A 2s external error of +/-0.000014 (or 0.3 eNd units) based on replicate runs of JNdi-1. |
| 7 | 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 | |
| 8 | 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 |
