    Isotopes of iron - Wikipedia

    • Naturally occurring iron (26Fe) consists of four stable isotopes: 5.845% of Fe (possibly radioactive with a half-life over 4.4×10 years), 91.754% of Fe, 2.119% of Fe and 0.286% of Fe. There are 28 known radioactive isotopes and 8 nuclear isomers, the most stable of which are Fe (half-life 2.6 million years) and Fe (half-life 2.7 years). Much of the past work on measuring th… 展开

    What is a stable isotope of iron?
    Iron has four naturally occurring stable isotopes: 54 Fe (5.84%), 56 Fe (91.76%), 57 Fe (2.12%), and 58 Fe (0.28%). Both 56 Fe/ 54 Fe and 57 Fe/ 54 Fe ratios are reported in the literature as δ 56 Fe and δ 57 Fe, respectively, most commonly relative to the IRMM-014 standard but also in some cases to average igneous rock ( Beard and Johnson, 2004 ).

    What is iron isotope work?
    Iron isotope work is premised on a strong experimental foundation that is the basis for interpreting both modern environmental and geological iron isotope signals and the system has, arguably, been used most extensively to track the evolution of redox-sensitive iron biogeochemical cycling through Earth’s early history and oxygenation.

    How are iron isotopes fractionated?
    Iron isotopes (typically reported as δ56/54 Fe values) can be fractionated by both abiotic and biological processes, and natural variations in δ 56 Fe values span a range of ~ 5‰ (see reviews in Anbar and Rouxel, 2007; Johnson et al., 2008 ).

    What is the isotopic composition of iron in natural samples?
    The isotopic composition of iron in natural samples has been measured since the 1940s by electron impact ionization and more recently by thermal ionization mass spectrometry (TIMS) after sample dissolution and chemical purification using anion exchange chromatography.
