Richard Hervig uses the chemistry of Earth and extraterrestrial materials to determine their origin and evolution. These materials include samples from volcanic eruptions, igneous intrusions, low to medium temperature metamorphic rocks, sediments, and the solid run products from experiments. The primary tool used to explore these samples is the secondary ion mass spectrometer (SIMS, or ion microprobe). SIMS is a microanalytical technique with applications to geochemistry, cosmochemistry, and materials science.
