| 7 | Neodymium-143/Neodymium-144 ratio | 143Nd/144Nd | Pierce, Elizabeth L | Calculated | Corrected; all reported 143Nd/144Nd ratios represent the average of two measurements and are corrected to a JNdi value of 0.512115, which equals a La Jolla value of 0.511858 (Tanaka et al., 2000, doi:10.1016/S0009-2541(00)00198-4). JNdi values on two separate measuring days were 0.512116 ± 0.000020 (2sigma S.D., n =11 and 0.512097 ± 0.000013 (2sigma S.D., n=13). Since the standard data showed a clear trend throughout the day, we first detrended the standard values, to then correct the JNdi value. | |
| 8 | Neodymium-143/Neodymium-144 ratio, error | 143Nd/144Nd e | ± | Pierce, Elizabeth L | Calculated | 2sigma S.E.; the 2sigma S.E. reported is the larger of the two internal errors of the two sample runs that were averaged |
| 9 | ε-Neodymium | ε-Nd | Pierce, Elizabeth L | Calculated | Calculations are based on a 143Nd/144Nd chrondritic value of 0.512638 (Jacobsen and Wasserburg, 1980, doi:10.1016/0012-821X(80)90125-9). |
