Modeling of HSE abundances of the IIF irons indicates a complex formation history that included the mixing of primitive and evolved solid and liquid metals. By contrast, modeling of HSE abundances of PES metal suggests these meteorites formed mainly as equilibrium solids from a common liquid. Abundances of some of the siderophile elements in the IIF irons and PES are permissive of a common core origin; however, the abundances of W and Ni indicate the PES ultimately formed on a more oxidized body. The PES most likely formed by the injection of olivine present at the core\u2013mantle boundary into a metallic core liquid as a result of impact. The core then crystallized inward, trapping the olivine.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Connor D. Hilton, Richard D. Ash, Richard J.
