Geochemistry

Geochemistry studies how Earth’s rocks, fluids, gases, and biological components interact over time. It uses chemical principles to deepen our understanding of the Earth system and the systems of other planets. Key areas include biogeochemistry, organic geochemistry, trace and elemental geochemistry, and metamorphic and igneous-rock geochemistry.

Our department is equipped with advanced tools, such as inductively-coupled plasma and stable-isotope mass spectrometers, a chromFTIR lab, a fully automated electron microprobe, X-ray diffractometer, laser Raman, and SEM, allowing you to explore these dynamic interactions hands-on as you prepare for your future.
