The deep etching of plessite particles in ordinary chondrites was carried out followed by an electron-microscope study of the metallic structures. This made it possible to obtain information on the fine structure of kamacite grains, the structure of polycrystalline kamacite, and the presence of inclusions of other minerals. Specifically, the fine structure of a large kamacite grain in the Zvonkovoe chondrite was investigated.
