The initial condition. Illustration of the initial distribution of a internal heating rate, b bulk composition, and c temperature. The assumed parameter values in the figure are: the temperature of the mid-mantle \(T_{{\text{M}}} = 1550\,{\text{K}}\); the ratio of the concentration of HPEs in the crust to the mantle \(F_{{{\text{crst}}}}^{*} = 8\); the thickness of the high-density layer after mantle overturn \(L^{*} = 1/5.5\)
