13.5 Pound Cut And Etched Campo Del Cielo Meteorite. This 7 x 5 x 3 inch iron-nickel meteorite has been cut in half, polished and etched on both inside sections to show the interesting silver and gray Widmanstatten patterns made possible because of the segregation of two nickel compounds, Kamacite and Taenite, which etch at different levels. These unique patterns define these specimens as meteorites because a slow cooling of not more than a few degrees per million years is necessary to allow the nickel alloys to separate and no rocks on earth have these patterns. Campos are of the category polycrystalline octahedite iron-nickel meteorites and are defined by wide bands in the Widmanstatten pattern. This example also exhibits the characteristic regmaglypts and fusion crust on its unaltered surface.
