Fmnh Meteoriticists Classify Rare Iron Meteorite

The meteorite was discovered on May 9, 2009, when it was unearthed by Jim Koch while he was preparing his field for alfalfa planting. A cut sample was sent to the Field Museum in March 2015, where it was confirmed and classified as an IVA iron meteorite. These are exceptionally rare, representing only about one per thousand of all known meteorites, and about 7% of all known iron meteorites. (This is the second meteorite classified by the Pritzker Center from the US Midwest found near a small town that shares its name with a major European city, the other being the Hamburg meteorite.) The classification was performed by Robert A. Pritzker Curator Philipp Heck, with help from Meteoritics Collections Manager Jim Holstein, and University of Wisconsin scientists Carrie Eaton, Noriko Kita, and Rich Slaughter. Research Scientist Laure Dussubieux also provided guidance in the Museum’s Elemental Analysis Facility. The classification was published in Meteoritical Bulletin, and you can read more in the University of Wisconsin News.
