TABLE 9. Changes to major lunar features: Mature surface stage

1. Scattered impact events produced relatively young, rayed craters.

2. Local impact events, implanation of solar wind gasses, and related processes, including the development of mature regolith, reached present day intensities.

3. Late, thermally induced evolution of volatiles from the deep lunar interior may have altered surface materials to create the bright swirls.
