A possible source for the Martian circumpolar dune materialThe properties of freeze dried dilute dispersions of dust in water are of considerable interest in studies of sedimentary processes in the polar regions of Mars. The formation of a rind residue due to the sublimation of water ice containing various amounts of clay may be an important step in these processes. Such phenomena may occur as the result of seasonal or long term (climatic) sublimation of dirty ice caps on Mars. The development and disruption of dust residues on the surface of ice dust mixtures as a result of preferential ice sublimation were simulated in the laboratory. The characteristics of the resulting particles are described and a scenario for the formation of a Martian circumpolar dune field is suggested.
