Title: Martian rampart and pedestal craters' ejecta-emplacement: Coprates quadrangle
Abstract: A study of the Martian rampart and pedestal craters in the Coprates quadrangle is presented. Relationships between crater size and ejecta-blanket areal extents imply a maximum ejecta-blanket thickness or maximum rim height for Martian rampart craters; the limiting thickness is encountered only for craters exceeding 6 km diameter. The larger craters have an additional component of internal flow of the ejecta caused by the greater weight of their thicker ejecta deposits, although smaller rampart craters have ejecta which appears to have undergone flow during emplacement; pedestal craters most likely result from impacts into less volatile-rich substrates which produce a less fluidized ejecta and no flow lobes.
