HP-PEDPM: High Pressure Phase Equilibria Database for Planetary Materials

High Pressure Phase Equilibria Database for Planetary Materials (HP-PEDPM) Dataset Description This data set presents the experimental data available in the literature on Fe, MgO, SiO2, and MgSiO3. While we have tried to include as much literature data as possible, the database may not be complete due to the large number of publications on these materials. This provisional version will be updated regularly as new data or previously overlooked literature becomes available. The latest version of the database is 2025verFeb11. A benchmark code to reproduce the phase diagrams (Figure 8) is now included. Data Structure The dataset consists of the following columns: Pressure (GPa): Pressure conditions under which the phase observations were recorded Temperature (K): Corresponding temperature at the given pressure Phase: Phase of the material observed at the recorded P-T conditions Author: Source Method: Technique used
