Abstract

Geoid models show that net uncompensated masses in subducting lithosphere are less than thermal models predict, and do not require elevation of mantle phase changes in the slabs. The largest deviations from hydrostatic equilibrium ignore plate boundaries and may be ascribed to lower mantle convection uncoupled to plate motions.
