Whole-mantle convection and the transition-zone water filter (2002, background): “The remaining water- and incompatible-element-enriched melt residue is likely to be denser than the solid phase because of the melt-solid density crossover that is inferred to exist above the transition zon”
Linked magma ocean solidification and atmospheric growth for Earth and Mars (2008, background): “…change of thousands of degrees is necessary, which would melt this thin, dense layer, and thus further stabilize it at depth because this melt is likely negatively buoyant with respect to the remaining cumulates (Stolper et al., 1981; Ohtani and Maeda, 2001; Bercovici and Karato, 2003; Agee, 2008).”
Magma oceans in the inner solar system (2012, background): “At still higher pressures, majorite may have a density crossover with coexisting liquids (Ohtani & Maeda 2001, Stixrude & Karki 2005, Mosenfelder et al. 2007), leading to a basal magma ocean (Labrosse et al. 2007).”
Letter. Aluminum coordination and the densification of high-pressure aluminosilicate glasses (2005, methodology): “These values are similar to the 20% densiÞ cation that has been observed for the compositionally more complex MORB melts at 5 GPa (Ohtani and Maeda 2001), which suggests that the rapid decompression can retain much or even most of the total densiÞ cation and structural changes found in the…”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “Extrapolations of laboratory data (Agee, 1998; Ohtani and Maeda, 2001) indicate that basaltic melt becomes denser than solid peridotite, although peridotitic melt does not.”
GEODYNAMICS AND RATE OF VOLCANISM ON MASSIVE EARTH-LIKE PLANETS (2008, background): “If the sinking rate exceeds mantle velocities, these denser melts may accumulate at the base of the mantle (Ohtani & Maeda 2001).”
LINKS BETWEEN LONG‐LIVED HOT SPOTS, MANTLE PLUMES, D″, AND PLATE TECTONICS (2004, background): “…conditions depends critically on the detailed chemistry and physical properties of the liquid phase and possibly the solid phase with which it equilibrates [e.g., Brown et al., 1987; Rigden et al., 1984, 1989; Knittle, 1998; Ohtani and Maeda, 2001; Moore et al., 2004; Akins et al., 2004].”
