| Why this differs from similar rows: Cites Wentzcovitch et al. [1995] ab initio MD result (Table 1); text notes this gives volumes ~2% smaller than experiment; sibling row cites Hemley et al. [1987] PIB model instead. | ||||||||||||||||

266 | 4.200 | Vinet | — | Original | ||||||||
| Why this differs from similar rows: Static-lattice parameters adopted directly from Stixrude and Cohen [1993] LAPW calculation; sibling row instead adjusts only V0 to better match specific experimental runs. | ||||||||||||||||
| Bridgmanite |

— | 160.452 ų Unit cell |
266 | 4.200 | Vinet | — | Original | ||||||||
| Why this differs from similar rows: V0 adjusted to 160.452 A3 to match isobars of runs 3A, 3B, and 8 of Wang et al. [1994]; K0 and K0' held identical to sibling row 546's adopted values. | ||||||||||||||||

263.900 | 4.180 | Vinet | — | Original | ||||||||
| Why this differs from similar rows: Least-squares fit combining Knittle and Jeanloz [1987] P-V data with Wang et al. [1994] zero-pressure data; sibling row is an alternative V0-only adjustment of this fit. | ||||||||||||||||
| Bridgmanite |

263.900 | 4.180 | Vinet | — | Original | ||||||||
| Why this differs from similar rows: Alternative V0=162.06 A3 (dotted lines, Figure 14) with K0 and K0' held identical to the fitted values in sibling row 548; only V0 differs. | ||||||||||||||||
