A comparison between hydrothermal alteration present in the Vargeão Dome and Vista Alegre impact structures (Brazil) and CRISM remote sensing data from impact structures on Mars

Impact-generated hydrothermal systems are considered a possible habitat for early life and are therefore of importance for the search of Martian life. To assess possible (past) impact-generated hydrothermal systems in Martian impact structures, two analogue structures on Earth, the Vargeão and Vista Alegre impact structures in Brazil, were...
