Crater degradation on the lunar maria: Topographic diffusion and the rate of erosion on the Moon

CI Fassett, BJ Thomson - Journal of Geophysical Research …, 2014 - Wiley Online Library
Landscape evolution on the Moon is dominated by impact cratering in the post‐maria
period. In this study, we mapped 800 m to 5 km diameter craters on> 30% of the lunar maria …

JD Stopar, MS Robinson, OS Barnouin, AS McEwen… - Icarus, 2017 - Elsevier
We assessed the morphologies of more than 930 simple impact craters (diameters 40 m–10
km) on the Moon using digital terrain models (DTMs) of a variety of terrains in order to …

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

DA Minton, CI Fassett, M Hirabayashi, BA Howl… - Icarus, 2019 - Elsevier
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 …
