Topography of the transition zone seismic discontinuities
2000 · cited by 263
The paper reviews how phase transformations in mantle mineralogies govern transition zone seismic discontinuities under thermodynamic and pressure changes.

The analysis

The retrieved literature consistently discusses mantle mineral phase transitions (such as spinel to post-spinel transitions or ringwoodite dissociation) occurring under high pressures and forming denser crystal structures that dictate seismic discontinuities and mantle dynamics. Papers 0, 4, and 11 explicitly support this geological fact. There are no papers refuting the claim.
