Distribution of Cl observed by Mars Odyssey GRS

John Keller

The global distribution of Cl on Mars is heterogeneous, varying from 0.2 to 0.8 wt%. A region of high Cl is centered over Medusae Fossae to the west of Tharsis. Cl correlates positively with H and negatively with Si and thermal inertia. Possible mechanisms influencing the distribution of Cl include aeolian, volcanic, aqueous, and hydrothermal processes.
