Serpentinite Materials: From Mantle to Microbes and Everything in Between II Posters

Submit an Abstract to this Session



Session ID#: 23345

Session Description:
Serpentinite materials, which form from the hydration of ultramafic rocks, are found globally in a variety of provenances within oceanic and continental lithosphere. Typical products of serpentinization include serpentine, brucite, talc, various metal alloys, and the release of hydrogen, which can react with carbon dioxide to form methane and other carbon compounds. Within the last decade, several deep-sea scientific drilling expeditions, land-based borehole studies, and other oceanic and continental
research expeditions have focused on serpentinite deposits to elucidate crustal fracturing and hydration prior to subduction, subduction and seisomogenic processes, lithospheric recycling and exchange, CO2 sequestration, metamorphic processes and transport, microbial activity and metabolic processes, potential pathways for the evolution of life on Earth, and the means to search for and detect life on other planetary bodies. This session will span the breadth of geological to microbiological studies to provide an interactive exchange of ideas at the center of multidisciplinary research centered on serpentinization.
