Biosignatures in Acid-sulfate hydrothermal systems

After ~3 billion years, Mars experience what is thought to have been a global acid-sulfate weathering event. These studies examined microorganisms’ influence rock dissolution, clay mineral precipitation, and trace element distributions in acid-sulfate hot spring systems in order to determine whether microbial processes might be differentiated during this period of Mars’ history.

Microbial Weathering in Acid-Sulfate Hot Springs

I have recently submitted an article on how microorganisms and their biofilms influence trace metal distributions (including gold, silver, arsenic, copper, zinc, and nickel) in acid-sulfate hydrothermal systems.
