The martian polar ice caps record a wealth of information about the environment and events on the surface of Mars. As on Earth, deciphering this rich record must include a sound chronology. The martian ice caps clearly exhibit stratification, one of the most critical requirements for establishing a relative chronology however, meaningful interpretation of data stored in the polar caps will require absolute dates. Stratification in the polar caps of Mars arises, at least in part, from the incorporation of eolian material in the ice. Active eolian processes are also exhibited near the poles in the form of dune fields. Eolian materials are ideally suited for luminescence dating and luminescence dating techniques have been used successfully to make absolute age determinations for numerous terrestrial Quaternary eolian deposits. Luminescence dating techniques could potentially be developed to provide absolute age determinations for the eolian sediments ubiquitous on the surface of Mars, including the sediments incorporated in the martian polar ice caps, thereby affording an opportunity to correlate events recorded at the poles with the record of eolian activity across the surface of Mars.
