Comment:

δ56Fe analysis of sequentially extracted Fe pools: • Processing after Henkel et al. (2016). Column separation after Schoenberg & von Blanckenburg (2005). Isotope analysis on a ThermoFinnigan Neptune Multicollector-ICP-MS (standard-sample bracketing method with IRMM-014) (Schoenberg & von Blanckenburg 2005).
