Italy originator GFZ Data Services publisher We report the results of high throughput, robust, and sensitive method for the precise analysis of 56Fe/54Fe and 57Fe/54Fe, performed using Multi-Collector-Inductively Coupled Plasma-Mass Spectrometer (MC-ICP-MS), Thermo Scientific Neptune PlusTM. We measured the Fe isotope compositions of widely used standard reference materials ranging from basaltic to rhyolitic compositions (JB-2, BHVO-2, BE-N, AGV-1, and RGM-1). We also propose a new iron isotope reference material, IAEA-B5, a basalt from Mount Etna already commonly used as a reference for B and Li isotopes.
