Sandstorms and eolian erosion on Mars

Abstract

It is now apparent that windblown sand plays a major role in the Martian environment. The existence of great sand and dust storms implies the lateral transport of large quantities of material on Mars that provide a convenient mechanism for the filling of craters- an event directly implied both by crater frequency-diameter statistics, and by the appearance of Martian craters. Such fast moving sand particles, saltating close to the Martian surface, can produce by collision and subsequent abrasion significant erosion of the Martian terrain.
