Paper Abstract

The salt geochemistry of Mars is predicted as an extrapolation of the salt geochemistry of the Dry (ice-free) Valleys in Antarctica. It is hard to escape the implication that there must be calcium/magnesium brine lakes in the enclosed drainage basins associated with the Northern Ice Cap. Because of the extreme cold these lakes will have acquired an ice cover. At the interface between the ice cover and the brine, one may find a thin layer of relatively fresh water. This might be the best and easiest place to look for Martian life.
