COMPARISON OF EQUILIBRIUM SIZE DISTRIBUTIONS FOR LUNAR CRATERS.
Abstract
Some theoretical models of crater destruction are considered to explain not only the exponent -2 of the equilibrium distribution of crater diameters, but also the density coefficient and its regional variations. Destruction of small craters appears to be governed principally by blanketing or filling by ejecta, and the equilibrium density coefficient decreases with increasing size of the largest crater affecting the region studied. Destruction of large craters seems to depend mainly on destruction of a substantial part of the crater wall by a crater of similar or greater diameter. Only certain south polar and farside continental regions appear to be saturated with craters. (Author)
