    Content: Carbonatite magmatism is a highly efficient transport mechanism from Earth’s mantle to the crust, thus providing insights into the chemistry and dynamics of the Earth’s mantle. One evolving and promising tool for tracing magma interaction are stable iron isotopes, particularly because iron isotope fractionation is controlled by oxidation state and bonding environment. Meanwhile, a large data set on iron isotope fractionation in igneous rocks exists comprising bulk rock compositions and fractionation between mineral groups. Iron isotope data from natural carbonatite rocks are extremely light and of remarkably high variability. This resembles iron isotope data from mantle xenoliths, which are characterized by a variability in δ56Fe spanning three times the range found in basalts, and by the extremely light values of some whole rock samples, reaching δ56Fe as low as -0.69 ‰ in a spinel lherzolite. Cause to this large range of variations may be metasomatic processes, involving metasomatic agents like volatile bearing high-alkaline ...

    ISBN: 9783030338282
    Series Statement: Advances in Isotope Geochemistry
    Content: Introduction and Overview -- Analytical Methods -- Fe Isotope Fractionation Factors -- High-Temperature Fe Isotope Geochemistry -- The modern surficial world -- The Ancient Earth.
    Content: This book provides a comprehensive summary of research to date in the field of stable iron isotope geochemistry. Since research began in this field 20 years ago, the field has grown to become one of the major research fields in "non-traditional" stable isotope geochemistry. This book reviews all aspects of the field, from low-temperature to high-temperature processes, biological processes, and cosmochemical processes. It provides a detailed history and state-of-the art summary about analytical methods to determine Fe-isotope ratios and discusses analytical and sample prospects.
