Web1 de ago. de 2024 · If the growth of QCMB is rapid enough, it can reverse the evolution of the mantle temperature. For the transition solution, both ΔTLM and TLM are increasing near t = − 3.61 Gyr and the heat flow from the core rises sharply, eventually exceeding QS near t = − 3.62 Gyr and moderating the mantle temperature in effect.
