“SEM image of micronugget of Iridian Ferronickelplatinum composed by crude cubic and cubooctahedral crystals intergrowth from heavy concentrate, washed on Bir Bir river banks. Dark in BSE material, filling cavities, is limonite with admixture of some unidentified iron phosphate. Compositional data are available on the daughter photo. For exact size look the micrometer bar. Pavel M. Kartashov analytical data, photos and collection.”
