Placers in the Yanshan area (which are otherwise composed of chromite, ilmenite, zircon, gold, PGE minerals, etc.) have been found to contain abundant spheres of "iron", typically 0.1-0.5 mm in size, which consist of an outer shell of magnetite, wüstite and maghemite and an inner shell of kamacite and taenite. In addition, some spheres have a core which is composed of gupeiite and xifengite.
