Abstract
Sulfur isotopes in pyrite have been widely used to understand local redox and geochemical conditions in Earth's past. By expanding our toolbox to include detailed analysis of organic sulfur and grain-specific pyrite isotope analyses, we can gain much greater insights into depositional environments as well as regional geochemical conditions. I will present results from a series of studies investigating paired organic–inorganic sulfur isotope records from Ocean Anoxic Event 2 as well as results from modern sites that help test our hypotheses from the rock record.
