How Hot is the Moon: Quantifying the Role of Heat-Producing Elements on the Present-Day Selenotherm with Partitioning Experiments and Conductive Thermal Modeling

Points• Reasonable present-day selenotherms produced by bulk U and Th abundances from dominantly enstatitic meteorites rather than carbonaceous chondrites • Mantle overturn and sinking of heat-producing-element-enriched high Fe-Ti cumulates associated with magma ocean crystallization was inefficient • Heat-producing element enriched high Fe-Ti cumulates are potentially present below the crust and fueled prolonged lunar volcanism
