[MIS25-02] A comparison of magma eruption fluxes between the Moon and Mercury
Keywords:Moon, Mercury, Volcanism, Dichotomy, Thermal Evolution
The ages and volumes of magma eruptions on planets and satellites are fundamental for understanding its thermal evolution. The Moon and Mercury, that are unique in terms of its size and its bulk density, provide us with key information on the thermal history for an endmember of differentiated planetary bodies. On the Moon, mare basalts occur preferentially in topographical lows on the nearside, and are rare on the farside. Similarly, smooth plains, the most common volcanic features on Mercury, are also distributed asymmetrically between the northern and southern hemispheres.
Eruption ages and volumes of mare basalts on the Moon and smooth plain materials on Mercury have been determined by many previous studies using remote-sensing data. In this study, we compiled the data and compared the volcanic fluxes between the Moon and Mercury. Based on the results, we will discuss the quantities of magma production and the causes of hemispheric asymmetries on the Moon and Mercury.
