Single-grain optical dating properties of JSC Mars-1: preliminary measurements of radiation dose response and sensitivity change.

Martian surface deposits, including polar deposits, represent a vast storehouse of data recording the evolution Of Mars' climate and surface environment. However, the greatest challenge to deciphering these martian geo-records is the need for absolute dating techniques, Particularly those techniques applicable to the timeframes and surface processes of the 'Martian Quaternary'. Lepper and McKeever [3,4] have proposed developing optical dating, an established terrestrial chronometric dating method based on principles eri'solid-state physics, for retnote in-situ dating oCrnartian surface seditnents.
