The effect of ilmenite viscosity on the dynamics and evolution of an overturned lunar cumulate mantle

Lunar cumulate mantle overturn and the subsequent upwelling of overturned mantle cumulates provide a potential framework for understanding the first‐order thermochemical evolution of the Moon. Upwelling of ilmenite‐bearing cumulates (IBCs) after the overturn has a dominant influence on the dynamics and long‐term thermal evolution of the lunar mantle. An important parameter determining the stability and convective behavior of the IBC is its...
