{"title":"Bison - LL6 Ordinary Chondrite","description":"\u003cp\u003eBison is an LL6 Ordinary Chondrite found near Bison in Rush County, Kansas, USA. The meteorite was recognised after a 3 kg stone was found in 1958, which led to the identification of an earlier 1938 stone as the same meteorite. Around 11 kg of material is recorded from two stones. As an LL Chondrite, Bison has low total iron and low metallic iron compared with H and L Chondrites, while its type 6 classification indicates a high degree of thermal metamorphism on its parent asteroid.\u003c\/p\u003e\n\u003cp\u003eBison is also described as an impact melt breccia, adding further interest beyond a standard equilibrated Ordinary Chondrite. Specimens may show a compact, recrystallised matrix with subdued chondrules, low visible metal, and areas affected by shock and melting. Published locality data records Bison as LL6, shock stage S4, and weathering grade W2, reflecting both significant pre-terrestrial impact history and moderate terrestrial alteration after landing.\u003c\/p\u003e\n\u003cp\u003eStudying Bison provides insight into the LL Chondrite parent body, high-grade thermal alteration, and impact melting within asteroid material. Its Kansas provenance, limited recovered mass, LL6 classification, and impact melt breccia character make it especially appealing for collectors of USA meteorites and unusual Ordinary Chondrites. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, altered by heat and shock before its arrival on Earth.\u003c\/p\u003e","products":[],"url":"https:\/\/outerspacer.com\/collections\/bison-ll6-ordinary-chondrite.oembed","provider":"OuterSpacer Meteorites","version":"1.0","type":"link"}
