Eastern Mineral and Environmental Resources Science Center
Radiogenic and Stable Isotope Methods
Work is focused on developing radiogenic and stable isotope analytical
techniques to support mineral- and environmentally-related geologic
- Radiogenic isotope techniques are used for analysis of materials,
fluids, and fluid and solid inclusions from ancient and modern environments.
New analytical procedures are being developed for studies directed at:
regional and site-specific metal mobilization, metal transport, redistribution
processes, and sources of fluids for regional geologic, ore genesis,
life-cycles, and environmental applications.
- Stable isotope work includes developing new and refining existing
analytical techniques for the following applications: (1) oxygen isotope
analysis of dissolved sulfate for studies of mine drainage, acid deposition
and ecosystems; (2) hydrogen isotope analysis of silicate and other hydrated
minerals for studies of ore genesis; and (3) sulfur isotope analysis of
submilligram samples of sulfide and sulfate minerals using continuous-flow
technology for environmental, ore genesis and ecosystem studies.
