Magma Buoyancy Couples Lunar Mantle Convection and Magmatism: Long-Lasting Mare Volcanism and Radius Change in a 3-D Regional Model

Ken'yo U, Masanori Kameyama, Takatoshi Yanagisawa +2

To understand the mantle evolution that has caused the observed histories of mare volcanism and radius change of the Moon, we developed a 3-D regional spherical shell mantle convec…

Partially Molten Plumes and Melt-Fingers: Two Modes of Magma-Transport through the Mantle in Terrestrial Bodies

Ken'yo U, Masanori Kameyama, Takehiro Miyagoshi +2

To understand the dynamics of partially molten mantle in terrestrial bodies, we carried out a linear perturbation analysis and 2-D numerical simulations of magma-matrix flow in a h…

Resurgence of Lunar Volcanism: Role of Localized Radioactive Enrichment in a Numerical Model of Magmatism and Mantle Convection

Ken'yo Uh, Masanori Kameyama, Gaku Nishiyama +2

We develop a 2-D numerical model of magmatism and mantle convection to understand the volcanism on the Procellarum KREEP terrane (PKT) of the Moon, which continued for billions of…

The volcanic and radial expansion/contraction history of the Moon simulated by numerical models of magmatism in the convective mantle

Ken'yo U, Masanori Kameyama, Masaki Ogawa

To understand the evolution of the Moon, we numerically modeled mantle convection and magmatism in a two-dimensional polar rectangular mantle. Magmatism occurs as an upward permeab…
