Stable isotope measurements are used to probe fundamental questions in the Earth and environmental sciences because they can be used to extract information about chemical, physical, and biological processes associated with the formation of geomaterials. Stable isotope patterns have been used for applications ranging from tracking the rise of oxygen on the early Earth to studying human diet. The majority of the course will focus on light isotope systems (O, C, S, etc.) and low-temperature applications, including: (1) tracing sources and sinks of fluids, sediments, biological materials, and contaminants, (2) studying rates and mechanisms of biochemical reactions, and (3) paleoenvironmental reconstructions. We will also review novel stable isotope applications including heavy isotope systems and mass independent fractionations. At the end of the course, students will be able to make interpretations about how stable isotope patterns inform our knowledge of how geomaterials are formed and provide information about the Earth system.
