Brenham – pallasite from USA Brenham is a pallasite meteorite, remarkable for its composition and discovery history. It is mainly found near the town of Haviland in Kansas, USA, and is one of the largest pallasites ever discovered. Pallasites are a rare type of meteorite, composed of iron-nickel metal and olivine crystals, giving them their characteristic appearance. Brenham was discovered in 1882 by H.O. Shepard, who found several small fragments in a field near Haviland, Kansas. Later, in 1928, Daniel Moreau Barringer, known for his work on the Meteor Crater in Arizona, financed further exploration of the area, during which additional parts of the meteorite were found. The total recovered mass is approximately 4.3 tons. The area around Haviland was repeatedly searched by enthusiasts and geologists. One of the largest fragments of the meteorite, weighing over 450 kg, was discovered in 2005 by Steve Arnold and Philip Mani. This discovery attracted significant media attention and popularity among meteorite collectors. Composition The Brenham meteorite is classified as a pallasite, a rare type of meteorite that contains approximately 50% metallic component (mainly iron and nickel) and 50% olivine crystals. These olivine crystals are usually transparent and can have different shades of green and yellow. When cut and polished, they give pallasites their unique appearance. Origin Pallasites, including Brenham, are considered fragments of the transitional zone between the mantle and the core of planetesimals or small protoplanets that formed in the early solar system. Their composition suggests that this is material formed under extreme temperatures and pressures.
