The equilibrium size-frequency distribution of small craters reveals the effects of distal ejecta on lunar landscape morphology [PDF]

, 2019
Small 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 of small ...
