Energetics of mantle convection and the fate of fossil heat
Apr 26, 2003 1. Introduction [2] The problem of the so-called missing heat source in the Earth's mantle has been central to our understanding of the style of mantle convection. The present-day terrestrial heat flux is ∼44 TW [Stein, 1995].About 80% of this global heat flux (i.e., ∼36 TW) comes from mantle convection, whereas the rest of ∼8 TW originates in continental crust.
