| title: | The long-term deformation of the Moon inferred from Kaguya geodetic data and implications for its thermal evolution |
| abstract: | In geologically long timescales, lunar large-scale topographies deform viscoelastically, and the thermal state strongly controls such deformations. In this study, we conduct (1) crustal structure analyses using Kaguya geodetic data and (2) long-term viscoelastic deformation calculations under a wide variety of conditions and investigate the early thermal evolution of the Moon. Our results suggest that deformations of large-scale topographies reflect proccesses that may have took place in the very early Moon, such as the magma ocean solidification and mantle overturn. |
