Isotopic fractionation of chromium and uranium during abiotic and microbial Cr(VI) reduction and microbial U(VI) reduction
… These reduction reactions fractionate Cr isotopes and alter the Cr stable isotope ratios. Cr stable isotope ratios can be used to track the extent of this reduction and thus can be used as a redox-indicator. The magnitude of the isotopic fractionation must be determined to connect observed …

Chromium and uranium isotopic exchange kinetics and isotope fractionation during oxidation of tetravalent uranium by dissolved oxygen
Chromium (Cr) and Uranium (U) isotopes (53Cr/52Cr and 238U/235U ratios) are very powerful new geochemical tools in environmental remediation and paleoredox reconstruction studies. Correctly interpreting Cr and U isotopic compositions in groundwater and sed- imentary rock samples requires thorough …
