The primary geological processes that have modified the lunar surface are impact cratering and volcanism, and by using standard stratigraphic principles (such as the law of superposition) it is possible to order these geological events in time. At one time, it was thought that the mare basalts might represent a single stratigraphic unit with a unique age, but it is now recognized that mare volcanism was an ongoing process, beginning as early as 4.2 Ga (1 Ga = 1 billion years ago) an…
