Gibeon meteorite Iron meteorite - 694 g

Gibeon was first found in Namibia, in 1838. It is classified as a type IVA fine octahedrite. Gibeon is one of the most sought after meteorites. This specimen is highly aesthetic and shows the classic Widmanstätten pattern, the form of crystallisation of iron in space upon cooling 1 degree Celsius per million years. The pattern is very thin and reflects light in different directions, as shown in the pictures. Iron meteorites are composed mainly of iron and nickel. Actually, they are a piece of an asteroid core. In the differentiation process, when the asteroid is a ball of magma, during its formation, iron and nickel settle to the core of the asteroid, as they are the heaviest elements. After cooling, the asteroid metal core is formed. Through catastrophic collisions, the asteroid and its core break and the fragments remain in space, until a piece falls to our planet. They are estimated to account for 5. 7% of falls. At Expometeoritos, we take care of dissemination, talks, workshops, analysis, classification and exhibitions of meteorites. We are members of: .
- IMCA (International Meteorite Collectors Association) #8187 .
- Meteoritical Society .
- American Meteor Society All our pieces are certified and, if the value of the piece is over €300, we also provide its chemical composition analysis, carried out in our facilities by X-ray spectrography.
