Martian fluidized crater morphology: variations with crater size, latitude, altitude, and target material.
Abstract
The paper investigates the influence of crater latitude, target material, and elevation on the morphology of the ejecta facies and crater interiors as a function of crater diameter. It is shown that only pancake craters exhibit latitudinal variation in their distribution. It is also shown that several crater types are associated with specific target materials: radial textured craters are found primarily on Tharsis and Elysium lavas, and pancake craters are found on fractured terrain, old lavas, and channel materials. Craters formed on recent lavas more frequently possess secondary craters, central peaks, and terraces than primary craters found on other geological units. The maximum radial extent of fluidized ejecta is demonstrated to be a function of crater altitude and latitude.
