Mode of occurrence, compositional zoning and bulk chemical composition of metals in the Yamato ordinary chondrites have been studied. Metal grains in the chondrites are discrete taenite and kamacite, and composite grains of the two phases including plessite. They show a remarkable compositional zoni...
