"Two fulgurites, both from York County, Pennsylvania, USA, showed the reduction of iron to iron metal with an assortment of Fe–Ti and Si–P compounds with stoichiometry that ranges from nearly pure Fe metal to FeSi. These metal silicides include stoichiometric Fe3Si, Fe2Si, and Fe5Si3, and possibly Fe8Si3 and Fe7Si3, and provide a terrestrial source for these phases, which are typically associated with extraterrestrial material."
