Studies of stable noble gases in Earth's crust, mantle and potential precursors have provided constraints on broad range of subjects, such as planetary evolution, fluid migration in the crust, tectonic activity, and paleoclimate. Naturally occurring radioactive noble gases (39Ar, 81Kr and 85Kr) are also fascinating new geochemical tracers. Using both stable and radioactive noble gases, I am exploring new and interdisciplinary fields of noble gas geochemistry.
Ongoing projects include:
etermination of crustal fluid migration rates using radioactive noble gases
Investigation of gas trapping efficiencies in water ice under conditions relevant to comet formation
Search for new noble gas paleotemperature proxies in crustal minerals
