| Why this differs from similar rows: Primary free fit to P-V-T XRD data (19-53 GPa, 300-2300 K) yielding both K_T0 and K'_T0; sibling row instead fixes K_T0 to 253 GPa and refits only K'_T0. | ||||||||||||||
| Bridgmanite |
|
300 K | — | 253 | 4.100 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: Alternative fit where K_T0 is assumed/fixed at 253 GPa and only K'_T0 is refit from the dataset; sibling row instead lets both K_T0 and K'_T0 vary freely. | ||||||||||||||
