Geochemical constraints on mantle structure and convection

Geochemical constraints on mantle structure and convection. Geochemical constraints on mantle flow. Heat flow budget. 44TW coming out of Earth but 6TW generated by radioactivity in continental crust. Maybe 10TW come from core, 20TW from radioactivity, leaving about 8TW from cooling.
