Impact craters on the Moon span five lunar geologic time periods, i.e., the pre-Nectarian System ... WebSmall craters of the lunar maria are observed to be in a state of equilibrium, in which the rate of production of new craters is, on average, equal to the rate of destruction of old craters. Crater counts of multiple lunar terrains over decades consistently show that the equilibrium cumulative size-frequency distribution (SFD) per unit area
