Diverse Geological Evolution of Impact Basins on the Moon

Impact basins are the dominant landforms on lunar surface, and their geological evolution varies. This research studied diversity in of three impact basins: Dirichlet–Jackson Basin, Nectaris Orientale Basin. First, regional topography geomorphology were using SLDEM2015 digital elevation model (DEM). Clementine ultraviolet–visible (UVVIS) data Moon Mineralogy Mapper (M3) used to study chemical composition mineralogical basins. Additionally, crust thickness have been subsurface structure The topographical analogies indicate that shapes cavity-like. However, shape basin is not an obvious cavity compared with other positions minimum maximum crustal located at center rim. uplift crust-mantle interface Basin relatively larger than Below maria collapses occurred crust–mantle interface. concentrations FeO TiO2 non-mare formation show expected bimodal distributions. Moreover, we found exposures olivine-rich materials which Rosse Maunder craters, respectively. These olivine may be explained by fact large basin, might penetrate blast away upper crust, excavating deep-seated material.
