Corn        35°24’18"N, 98°44’56"W

Oklahoma, USA

Found: 1994

Classification: Ordinary chondrite (H5)

History: Found by Mr. Kenton Gossen in 1994, in a pasture 2 miles north and 2 miles east of Corn, Washita Co., Oklahoma. Mr. Gossen took the specimen to Southwest State College and was told it was not a meteorite, but he kept it on the shelf in his office until meeting Ms. Sandra Cloud, a science teacher at Corn Bible Academy. In March 2011, Ms. Cloud brought the meteorite to the Kansas Meteorite Museum and Nature Center in Haviland, where the curator (Dr. Donald Stimpson) identified it as an ordinary chondrite and arranged to purchase it.

Physical characteristics: A single, large brownish stone weighing 5176 g.

Petrography: (A. Irving and S. Kuehner, UWS) The specimen is somewhat recrystallized but some chondrules remain. Primary minerals are olivine, orthopyroxene, sodic plagioclase, chromite, troilite and some kamacite (partially altered to iron hydroxides).

Geochemistry: Olivine (Fa17.9-18.3), orthopyroxene (Fs16.0-16.6Wo1.2), clinopyroxene (Fs5.8Wo45.8-46.1).

Classification: Ordinary chondrite (H5, S2, W2).

Specimens: A total of 21 g of sample and one polished thin section are on deposit at UWS. The main mass was purchased by DStimpson for the Kansas Meteorite Museum.
