“…On Earth, interaction with the atmosphere and/or fluids in target rocks are responsible for multiphase ejecta formation, transfer of 1.5-2 crater radii for a continuous ejecta blanket (e.g., Barlow, 2005), and on the order of 2-3 crater diameters for distal ejecta (e.g., Melosh, 1989). Sturm et al (2013) recently demonstrated that the Ries ejecta blanket in southern Germany contains a massive and continuous, dual-layer rampart structure at 1.45-2.12 crater radii from the crater center, whereas the most distal coarse-grained ejecta (the lithic ejecta clasts of the ''Ries-Brockhorizont'') was identified in fluvial sandy deposits of the North Alpine Foreland Basin in northern Switzerland nearly 200 km ($8 crater diameters) away from the Ries crater rim (Hofmann and Gnos, 2006;Buchner et al, 2007;Alwmark et al, 2012). Crucial factors for the acceleration and distribution of impact ejecta such as velocity, angle and property of the impacting body have been discussed in detail (e.g.…”
