Iron has four stable isotopes. Isotopic variations occur during changes in redox state. In particular, biologically mediated redox reactions result in large isotopic variation thus making iron isotopes a potentially useful tracer for the presence of life in extraterrestrial samples.

Additional information on iron isotopes is not yet available on this site. Visit the following for general information on iron isotopes:
