The Moon as an archive of collisional processes in the Solar System: New Views from Apollo samples and lunar meteorites

The Moon is an archive of impact cratering in the Solar System throughout the past 4.5 billion years. All of the Moon’s large impact basins were formed between ~4.5 Ga and ~3.8 Ga, however, the duration and magnitude of basin-formation is still currently not well known and the lunar impact record is controversial. This talk will give an overview of the topic, and discuss how new chemical and mineralogical analysis of Apollo samples has provided insights to the types of impactors that were striking the Moon, and how the lunar meteorite sample collection is revealing about the timing of lunar impact events.
