Exobiological implications of potential sedimentary deposits on Mars

摘要: Abstract One of main objectives the Mars exploration in 21st century is to search for evidence present or ancient life. Sedimentary processes are important on Martian surface. However, styles sedimentation can be different from its terrestrial counterpart some aspects because relatively stable crust and lack a continuous active surface hydrological cycle. Certain types sedimentary deposits Earth closely linked biological activities, searching such potentially enhance chance finding life planet. A wide range hypothesized siliciclastic non-siliciclastic particular interest future exobiological exploration.
