DCO ID 11121/9343-5940-2752-2240-CC

description

  • This research will address (1) the role of water-rock reactions, with a specific focus on serpentinization, in the production of reduced gases including hydrogen and methane, (2) the rates of reaction in low- and high-temperature systems, mafic and ultramafic terrains, and in rocks of varying degrees of age and alteration, and (3) the development of models of reduced gas flux on a global scale.

    Key global sample sites (continental; oceanic) will be identified that provide gases, fluids, and solids that can be interrogated with multiple methods to assess the three areas identified above. The team will use gas and fluid isotope (stable and noble) geochemistry including isotopologues, mineralogy and mineral chemistry, bulk rock chemistry, and micro-imagining and spectroscopy.
