Brunner, Benjamin; Coleman, Max L., 2005, "Δ17O of Martian sulfate : assessment as a tool to recognize the impact of biological sulfur cycling on Mars.", https://hdl.handle.net/2014/41241, Lunar and Planetary Science Conference, League City, Texas, March 14-18, 2005., JPL Open Repository
The Mars Rover-missions demonstrate that there are accessible Martian sulfate deposits (evaporites). These sedimentary rocks could indicate influence of past or present biotic processes even in the absence of traces of extraterrestrial life. We evaluate the potential of the analy... |
