Brenham[1] is a pallasite meteorite found near Haviland, a small town in Kiowa County, Kansas, United States. Pallasites are a type of stony–iron meteorite that when cut and polished show yellowish olivine (peridot) crystals.

The Brenham meteorite is associated with the Haviland Crater.

History[edit]

In 1949, a collector named H.O. Stockwell discovered a mass of 450 kilograms (990 lb), known at the time as "The World's Largest Pallasite Meteorite."

In October 2005, geologist Philip Mani and meteorite hunter Steve Arnold located and recovered the largest fragment ever found of Brenham: a single pallasite mass of 650 kilograms (1,430 lb).[2]

Classification and composition[edit]

Brenham is an anomalous pallasite (Pallasite-an).[1]

Specimens[edit]

The 650 kilograms (1,430 lb) mass found by Philip Mani and Steve Arnold is currently housed in a private collection in Texas.

The 450 kilograms (990 lb) mass discovered in 1949 is called The Space Wanderer and is on display at The Big Well in Greensburg, Kansas. It was found and hand dug in the Ellis Peck farm, east of Greensburg.

The world's largest collection of Brenham meteorites along with numerous fragments weighing a total of 8,500 pounds[citation needed] are housed at the Kansas Meteorite Museum and Nature Center in Haviland, Kansas owned by Don I. Stimpson & Sheila M. Knepper.[3]
