Investigating Mars Analog Sites for Understanding Aqueous Outcrops on MarsDr. Bishop will present results from CRISM analyses of aqueous outcrops on Mars and how these materials were characterized through comparison with terrestrial analog sites. Alteration of volcanic ash and tephra on Earth provide an understanding of the kinds of phyllosilicates, sulfates and other hydrated phases that we are finding on Mars through volcanic alteration. Similarly, hydrothermal alteration study sites on Earth help understand the affects of hydrothermal alteration on Mars through impacts. Finally, investigation of cold analog sites such as the Antarctic Dry Valleys enable characterization of alteration mechanisms proceeding in the current Martian environment.
