Radiogenic and stable isotope geochemistry: isotopic systems and their applications in the Earth sciences.
Instructors: Profs. Terrence Blackburn and Jim Zachos.
Script, record, and produce five 10-20 minute videos demonstrating isotope geochemistry laboratory methods and narrating the progression of a geochemical study. Collected isotopic data for students to interpret in final project. (Remote Instruction)
Rock sample preparation, including wet chemistry methods (sample digestion and ion-exchange column chemistry), fundamentals of mass spectrometry, and various isotopic analysis methods: carbonate δ13C and δ18O by iRMS; carbonate 87Sr/86Sr by TIMS; carbonate 230Th-232Th-234U-238U by ID-TIMS; water δD, δ17O, and δ18O by laser analyzer; and organic C and N abundance, δ13C, and δ15N by CN-EA-iRMS.
