Session ID#: 8394
Session Description:
This session will focus on the most recent discoveries of the complex hydration reactions of ultramafic rocks in which olivine and pyroxene are reacted to form rocks that are dominated by serpentine, brucite, talc, magnetite and carbonates and are associated with H2 and/or CH4 seeps. Serpentinization involves volume expansion, exothermic heat release, and crustal deformation, coupled with changes in fluid chemistry and seismic properties of the host rock. New insights into how serpentinization reactions proceed and importance of serpentinization as an energy source for microorganisms have been developed from studies on ophiolites and hydrothermal systems.
We invite investigations that concern different aspects of serpentinization such as physical, chemical or biological processes, petrology, fluid-rock processes, mechanics, kinetics of the reactions, volatile transfer (CO2, H2O, O2, SO2), or studies on carbon sequestration and abiotic generation of methane on natural, experimental and numerically modeled systems on Earth and planetary environments.
