The timeline of the lunar bombardment: Revisited (2018, background): “ly depleted in HSEs (10 4 to 10 5 ppb as shown above). Some authors consider that the high-density material sank all the way to the bottom of the mantle where it formed a global layer above the core (Zhong et al., 2000; Stegman et al., 2003; Scheinberg et al., 2015). If this assemblage contained suc”
Re-examination of the lunar magma ocean cumulate overturn hypothesis: melting or mixing is required (2002, background): “[7] suggested that the high-Ti cumulates sank to the core^mantle boundary, and then rose, melted, and erupted at the time of mare basalt genesis.”
A 3‐D numerical study of the thermal evolution of the Moon after cumulate mantle overturn: The importance of rheology and core solidification (2013, methodology): “This hemispheric asymmetry has been used to argue for large-scale (degree one) convective instability of the lunar mantle during overturn [Parmentier et al., 2002] or as it evolved after overturn [Zhong et al., 2000].”
Asymmetric thermal evolution of the Moon (2012, background): “This effect was not considered in our model, nor is it in other lunar evolution models [e.g., Zhong et al., 2000; Hess and Parmentier, 2001; Spohn et al., 2001; Stegman et al., 2003; Ziethe et al., 2009], as the composition of the lunar mantle is not well known.”
Thermal and Magmatic Evolution of the Moon (2006, methodology): “…the high abundance of incompatible elements within and/or beneath the crust of Oceanus Procellarum, in fact, do predict extremely high temperatures that might be sufficient to make these magmas positively buoyant in the crust (Parmentier et al. 2000; Wieczorek and Phillips 2000; Zhong et al. 2000).”
Constraints on the depths and temperatures of basaltic magma generation on Earth and other terrestrial planets using new thermobarometers for mafic magmas (2009, background): “It has been suggested that Lunar basalt generation was due to degree-1 (hemispheric wavelength) convective overturn of a stratified Lunar mantle that had been emplaced by crystallization of the Lunar magma ocean (Hess and Parmentier, 1995; Zhong et al., 2000).”
