| Abstract: | A mantle temperature profile is presented, which was obtained by solving the global energy balance equations. A sharp temperature increase across the mid-mantle transition zone inhibits a simple downward-extrapolation from the near surface data. However, this problem is solved in the context of studying the cooling process of the Earth. As the present-day value, the temperature at the base of the mantle was obtained to be 2 940K. At the mid-mantle transition zone, the temperature became 2 040 K with a sharp change of 310 K across the mid-boundary layer. At the base of the surface boundary layer it was obtained as 1 610 K. |
