Inferring blocked mantle convection
Science, 2019Geophysics The boundaries between rocks with different physical properties in Earth's interior come from either a change in crystal structure or a change in chemical composition. Wu et al. examined the roughness of the boundary between Earth's upper and lower mantle, thought to form from a change in mineral structure (see the Perspective by Houser). To

Geochemical Reservoirs and Whole-Mantle Convection
Mineralogical Magazine, 1998There are currently four rather separate approaches to study the evolution and present state of mantle dynamics, (1) geochemical characterization of mantle reservoirs by studying isotopes and trace elements in mantle rocks and mantle-derived melts, (2) high-pressure mineralogy, (3) numerical simulation of mantle convection, and (4) seismic tomography ...

Lagging mantle convection, the geoid and mantle structure
Earth and Planetary Science Letters, 1984Abstract In numerical models of convection incorporating migration of a simulated subduction zone, the main descending flow lags far behind the migrating trench, and a geoid low is associated with the main descending flow. This provides physical plausibility for the suggestion by Chase and Sprowl that present very long-wavelength (degree 2–4) geoid ...
