From: A coupled core-mantle evolution: review and future prospects
Onset of the surface plate motion in the coupled core-mantle evolution model (after Nakagawa and Tackley 2015). a–c Top: Surface mobility; Middle: Surface heat flow; Bottom: Magmatic heat flow zoomed up first 80 Myrs for three values of the friction coefficient of the oceanic lithosphere. a 0.02, b 0.04, c 0.08, and d the time variation of the viscosity field near the onset timing of the plate subduction. Top: A case with melting; Bottom: A case without melting. The friction coefficient is used as 0.08
