In order to place constraints on the composition and thermal history of the lunar mantle, in this study, we investigated the relationship between the eruption ages and Ti contents of mare basalts. We found that an increase in Ti content occurred at 2.3 Ga in the Oceanus Procellarum and Mare Imbrium regions, suggesting a possible magma source transition. The eruption ages of mare basalts suggest that a peak of volcanic activity may have occurred from 2.3 to 1.5 Ga. From these results, we propose a hypothesis that a high-Ti hot plume ascending from the core-mantle boundary generated the increase in Ti content and the peak of volcanic activity.
