The primary sources of thermal energy for mantle convection are three: (1) internal heating due to the decay of the radioactive isotopes of uranium, thorium, and potassium; (2) the long-term secular cooling of the earth; and (3) heat from the core.
This, however, requires the use of physical constraints that originate in laboratory measurements of mantle minerals at the conditions relevant to Earth’s interior, i.e., the compilation of mineral physics databases that will allow us to model mantle structure as a function of pressure, temperature, and composition.
This paper describes a quantitative approach that combines data and results from mineral physics, petrological analyses of mantle minerals, and geophysical inverse calculations, in order to map geophysical data directly for mantle composition (major element chemistry and water content) and thermal state.
The study of mantle plumes, their sources and chemical heterogeneity in the mantle has generated important hypotheses and ideas about major mantle processes such as convection, recycling of crustal materials and mantle residence times, as well as the nature of interactions between various reservoirs throughout the Earth system.
However, we will also describe methods for more complicated and realistic mantle situations by including compressibility, non-Newtonian rheology, solid-state phase transitions, and thermochemical (i.e., multicomponent) convection (Section 7.05.5).
Such work will benefit from collaboration across geochemical laboratories, as well as among geochemists, mineral physicists, seismologists and geodynamicists. The mantle of the Earth influences many dynamic processes such as crust formation, recycling and mantle convection.
