Abstract
The form of the lunar impact crater size-frequency distribution is discussed. Latest results on the lunar cratering chronology in the first 1.5 Ga after its formation are reviewed. It is shown that most cratering arguments speak against an extraordinary high flux increase (‘cataclysm’) at ca . 4 Ga ago. From age determination by crater frequency measurements, it is concluded that the dominant process of the formation of light (Cayley) plains is not deposition of basin ejecta but an endogenic one.
