Item Details
Description
Canyon Diablo Iron-Nickel Meteorite Slice with Widmanstatten Pattern. This 178.1 gram 4 ½ X 2 ½ inch Canyon Diablo iron-nickel meteorite slice has been polished and etched on both sides to show its Widmanstatten pattern. Widmanstatten patterns result from acid etching the polished surface of an Iron-Nickel meteorite. The low nickel (5%-15%) Kamacite iron-nickel alloy and the high nickel (up to 50%) Taenite iron nickel alloy etch at different rates in the acid. This Widmanstatten pattern is not found in any Iron-Nickel alloys since it only forms when the alloy cools very slowly only a few degrees over a million years. Estimated Value $200 - 500
Collection of Richard Kosta.
