Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history. Techniques have been developed for measuring all four sulfur isotopes, including the low abundance sulfur-36 (0.02 per cent) to 0.2 per mil, in situ for sulfides. This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on proces ....Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history. Techniques have been developed for measuring all four sulfur isotopes, including the low abundance sulfur-36 (0.02 per cent) to 0.2 per mil, in situ for sulfides. This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on processes occurring in the early solar system, atmospheric and hydrologic conditions in the Archean, ore-forming processes, and evolution of life on Earth.
