  1. Iron Isotope Cosmochemistry

    Wang, Kun2014

    <p>Iron is the most abundant element in the Earth and the 4th most abundant in the crust and mantle; Fe is involved in every stage of planetary formation and differentiation. Iron isotope ratios are robust process tracers used to understand the origin of the Solar System, planetary formation, and …
