Web17 jul. 2011 · By measuring neutrinos from deep in the Earth, Berkeley Lab scientists and their colleagues at Japan’s KamLAND neutrino detector have published the most precise estimate yet of radiogenic heat. A main source of the 44 trillion watts of heat that flows from the interior of the Earth is the decay of radioactive isotopes in the mantle and crust. In the mantle, temperatures range from approximately 500 K (227 °C; 440 °F) at the upper boundary with the crust to approximately 4,200 K (3,930 °C; 7,100 °F) at the core-mantle boundary. The temperature of the mantle increases rapidly in the thermal boundary layers at the top and bottom of the mantle, and increases gradually through the interior of the mantle. Although the higher temperatures far exceed the melting points of the mantle rocks at the surface (about 1… WebDaniel Nelson.
