Sulfide minerals are ubiquitous in meteoritic material and can provide information regarding the processes that have affected chondritic parent bodies. In this work, we look at sulfide grains within aqueously altered CI and CM chondrites. Previous work has shown that increasing aqueous alteration can modify the chemical composition of sulfide grains [1-3]. Sulfate minerals formed by the oxidation of sulfides ; this should have left a mark on the isotopic signature of the sulfide grains, as the newly formed sulfates incorporate 32S preferentially.
