Trace Element Geochemistry
Trace Element Geochemistry

| Trace-element geochemical studies can provide significant insights into geologic
processes. EES-1 researchers have used trace-element geochemistry to study: volcanologic
problems, fluid-rock interactions, contaminant transport in the environment, hydrothermal
systems, fossil fuels, and metamorphic processes. EES-1 emphasizes research that
integrates field-work, analytical investigations, and geochemical modeling. Analytical
capabilities in this area include ICP, XRF, and AA systems for analyses of waters, gases,
and whole-rock samples and micro-PIXE and SIMS for in-situ microanalytical trace-element
determinations. Recent studies have investigated the dynamics of silicic magma chambers, coal-forming processes, trace-element metasomatism in subduction zones, the origins of vadose-zone calcites at Yucca Mountain, and the formation of gold deposits. For further information contact:
