300 K | 27.45 cm³/mol Molar |
236 | 3.900 | third-order Birch-Murnaghan | — | Original | ||||||
| Why this differs from similar rows: This study's own EDXRD LHDAC fit (18-96 GPa) with V0, K0, K' fixed from Shim et al. [2000] static-compression results; only gamma0 and q fitted here. | ||||||||||||||

300 K | 27.45 cm³/mol Molar |
232 | 4.800 | Birch-Murnaghan (order unspecified) | — | Cited | ||||||
| Bridgmanite |
|
300 K | 24.43 cm³/mol Molar |
262 | 4 | Birch-Murnaghan (order unspecified) | — | Cited | ||||||
| Why this differs from similar rows: Cites literature parameter set of Jackson and Rigden [1996] (K'=4 assumed per footnote); sibling row cites a different original study (Fiquet et al. 2000). | ||||||||||||||

300 K | 24.43 cm³/mol Molar |
259.500 | 3.690 | Birch-Murnaghan (order unspecified) | — | Cited | ||||||
| Why this differs from similar rows: Cites Fiquet et al. [2000] LHDAC XRD result; sibling row instead cites Jackson and Rigden [1996]'s literature parameter set. | ||||||||||||||

| Why this differs from similar rows: Fit of earlier 300 K DAC data to 130 GPa (Tamai/Yagi, Yagi, Tarrida/Richet, Mao 1989) with K' assumed=4; authors argue this K0 is biased high by nonhydrostatic stress. | ||||||||||||||
