Crater size-frequency distributions on the ejecta blankets of Aristarchus and Tycho Craters are highly variable, resulting in apparent absolute model age differences despite ejecta being emplaced in a geologic instant. Crater populations on impact melt ponds are a factor of 4 less than on the ejecta, and crater density increases with distance from the parent crater rim. Although target material properties...
On terrestrial planets, flow-like deposits of impact melt are commonly found exterior to fresh impact craters. Often, these deposits are asymmetric about the crater rim, and the direction of flow may relate to either the pre-impact topography or the impact azimuth. In this work, we seek to determine the primary mechanism responsible for impact melt emplacement on two very different terrestrial worlds:...
