Polished And Etched End Cut Campo Del Cielo Iron-Nickel Meteorite. This large end cut 4 x 2.75 inch over two pound (920 grams) Campo del Cielo iron-nickel meteorite has been cut, polished and etched on two sides to show the interesting Widmanstatten patterns made possible because of the segregation of two nickel compounds Kamacite and Taenite which etch at different levels. This pattern defines these iron-nickel 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. Campo del Cielo meteorites are found in Gran Chaco Gualamba, Argentina about 500 miles northwest of Buenos Aries. Campos are of the category polycrystalline ochahedrite iron nickel meteorites and they are defined by wide in the widmanstatten pattern. End pieces are desirable because they still display the original surface of the meteorite on two sides and the interior structure on the two polished and ecthed ends. This is certainly a large enough specimen to get a good feel for the internal pattern and still possess some original surface with some small regmaglypts (thumbprints).
