Minimum effective area for high resolution crater counting of martian terrains (January 2015)

Abstract Excerpt: The acquisition of high-resolution imagery for the surface of Mars has enabled mapping of spatially limited (order of less than 103 km2) landforms such as alluvial fans, deltas, and lacustrine deposits that are targets for exploration due to their association with liquid water. It is essential for our understanding of the planet’s geologic and climate history therefore to place these landforms within the global chronostratigraphic context. Here, we analyze both the statistical variability in the cratering pattern as well as the influence of small crater resurfacing on crater counting small landforms.
