| Research Abstract |
Interdisciplinary approach among research groups allow us to reproduce rock - hydrothermal solution reactions, which provide useful data for better understanding of relationship among rock alteration, generation of reducing hydrothermal solutions and deep subseafloor eco-systems. We found abundant hydrogen generation both in the ultramafic rock - hydrothermal solution reaction systems and the fault systems, based on our experimental results. We also developed the system to observe rock - water - microbe interaction and polymerization of amino acids in the experimental system.
