Abstract— The nonmagnetic separates of Antarctic H‐ and L‐chondrite finds from the Lewis Cliff stranding area are enriched in Fe and siderophile elements such as Ni, Co, Cu, As, Ir, and Au, relative to those of non‐Antarctic falls. The siderophile enrichments are caused by the oxidation of metallic...
