Gibeon Meteorites were discovered in the 1830's in Namibia.
Meteorites are igneousrocks formed in space.
They consist of various minerals and their chemical composition differs greatly.
Typical rock-forming minerals in meteorites are olivine, pyroxenes,
Fe and Ni alloys and sulfides, rarely you might find organic matte also.
Meteorites fall into four main groups, according to metallic iron and silicate component: iron mereorites, Siderolite, Chondrite, Achondrite.
Radiometric dating places the age of crystallization of the iron-nickel metal in the Gibeon at 4 billion years.
