Excavation depth

Various estimates for the depth of excavation de are in the literature. Based on stratigraphic considerations, at Barringer Crater (Shoemaker, 1963), where D is the final rim diameter. The maximum de of material in the ballistic ejecta deposits of the Haughton and Ries structures is 0.035Da (Osinski et al., 2011), where Da is the apparent crater diameter. If the final rim diameter D is used, which is the parameter measured in planetary craters, a value 0.05D is obtained for Haughton. No other data are available for de in terrestrial complex impact craters.
