Many quasi-circular depressions (QCDs) revealed in the Mars Orbiter Laser Altimeter data set have no obvious structural representation in visible images of Mars. It has been suggested that these QCDs are surface representations of buried impact craters, and on the basis of this assumption, cumulative count versus diameter plots of QCDs in the northern lowlands have been constructed to date the buried lowland floor. If the QCDs are, in fact, buried impact craters, their surface relief should scale directly…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
