Earth Chemistry

---

We measure isotopic compositions, chemical and molecular abundances, to constrain timing and the nature of processes involved in geologic, paleobiologic, and planetary systems. Areas of current interest include…

• Abundances of chemical elements and their isotopes as they are fractionated in geological processes
• Evolution and prehistory of the solar system through analysis of lunar rocks and soil, as well as refractory inclusions and presolar grains in meteorites
• Evolution of the early Earth with regard to the formation of the earliest continental crust and implications for the atmosphere and hydrosphere
• The nature of orogenic events utilizing temperature and rate dependent systems
• Tracing the evolution of life through analysis of biomarkers and molecular fossils
• The origin and evolution of massive ore-bodies through a combined isotopic, chemical and petrologic approach
