Presentation Transcript

  1. Topic List: To be modified based on student interest • Background and Theory • Fractionation • Tracing the hydrologic cycle • Isotope effects • Paleothermometry • Rock-water interaction • Carbon Isotopes • Strontium • Cosmogenic • Sulfur • Nitrogen

  2. Hydrogen Isotopes • Example • 1H: Protium, no neutrons, mass = 1 amu; stable • 2H: Deuterium – extra neutron, mass = 2 amu; stable • 3H: Tritium – two extra neutrons, mass = 3 amu, radioactive t1/2 = 12.3 yr

  3. Equilibrium Fractionation

  4. Light Stable Isotopes • Clark and Fritz, 1997

  5. Isotopic variation • Hoefs, 2004

  6. Oxygen variation • Hoefs, 2004

  7. Hydrogen variation • Hoefs, 2004

  8. Carbon variation • Hoefs, 2004

  9. Nitrogen Variation • Hoefs, 2004

  10. Sulfur variation • Hoefs, 2004
