Session Description:
Laboratory investigations of mineral-organic chemistry are essential in planetary analogue research for astrobiology in order to understand chemical biomarkers, potential physical biosignatures, and the original in-situ biology present in a geological system. Many water-rock and water-mineral interactions can drive reactions relevant to prebiotic chemistry and/or provide energy to support extant life, and these processes can leave a significant amount of physical and/or chemical traces after the fluvial activity has ended. Furthermore it is critical to understand the geobiological pathways, quantified by biotic evidence, from the original organics to their in-situ habits to laboratory analogues testing the limits of habitability. For biotic processes this requires an interplay between microbiology, planetary geobiology, chemistry, and sedimentology. This session will address the mineral-organic interactions relevant to life origins, astrobiology, and detection that may have occurred on Mars and other terrestrial worlds, and show pathways toward deconvoluting these signs from abiotic or prebiotic processes.
