Morphologic classification of Martian craters and some implications
Abstract
The establishment of the absolute age range for the unmodified crater class is considered in an attempt to estimate the change of crater degradation rates as a function of time. It is assumed that both the Moon and Mars have had similar time rate of changes in impacting rates. This means that both were subjected to intense bombardment in early history. The rate rapidly declined to low rates around 3.5 b.y. ago.
