This investigation examines the grüneisen parameter's variability in geophysical minerals, highlighting implications for thermodynamic properties.

The study reveals that the grüneisen parameter decreases as the compression ratio declines across three minerals, indicating important thermal and elastic properties.
For MgO, the grüneisen parameter ranges from 1.125 to 0.98935 across different equations of state, showcasing significant differences in sensitivity to compression.
Using advanced equations of state, the modified Lennard-Jones equation shows the least sensitivity while the Brennan-Stacey equation exhibits the most, affecting theoretical predictions.
These findings enhance the understanding of geophysical phenomena such as mantle convection and seismic wave propagation by modeling thermodynamic properties accurately.

Srivastava et al. (2024) studied this question.
