Research Objectives
The goal of this project is to isolate and identify the various air-derived noble gas components in sediments, particularly (but not exclusively) those sediments associated with hydrocarbon systems. This project is designed to address how noble gas elemental patterns are acquired and retained in rocks and minerals and how they are transferred to the fluid phases in which they have been measured.

 (a) Cartoons depicting the diffusive flow of noble gases through an angstrom-scale half-space (carbon nanotube) and a system of labyrinths and constrictions; (b) relative enrichment/depletion of noble gases as a function of time and effective diffusivities (Kd) and throat constriction diameters (th). The F(Ne,Xe) values are the abundances of the Ne and Xe with respect to Ar, normalized to the Ne,Xe/Ar ratios in air.
