Origin: Africa, Namibian desert.
A meteorite is a solid piece fallen on the Earth´s
surface from space, which has been preserved during the penetration to the
atmosphere. The age of the object is about four billion years. It´s origin is
eighter from a large broken asteroid or planet (a particle from the center/heart
of the planet). For the largest part of the meteors that hits the Earth´s
atmosphere glow so that they become non-existing, but pieces that weigh >1 kg
usually manages to penetrate the frictional border.
The first Westerner who found this meteorite was the
English Army Captain, Explorer Sir James E. Alexander. The local inhabitants the
Kalahari Desert, Nama-tribesmen used it to make tools and weapons out of it.
elements of the Earth are similar to those which the meteorite posesses. The
distribution of the elements are different, they are more similar to those which
the inner parts of the Earth contains. The chemical composition is mainly iron
and nickel, other components are cobalt, phosphor, copper and chromium.
precise description of the Meteorite
The origin of the stones are from the
meteorite-belt between Mars and Jupiter, from where they have travelled into the
attractive gravity force ot the Earth, and from where they have fallen on the
Earth´s surface. This found is not only one meteorite, but from several
pieces of a shattered groupe of Meteorites that has hit the Earth at the same
time, on a area that is about: 350 x 100 km:s. The Gibeon was mostly found lying
on the desert. The name
given to a Meteorite usually is directly related to the geological place where the meteorite has dropped/fallen. The area has
already been picked, and today finding the pieces has been getting
more difficult, but due to metal detectors, there are still material being found
on the site, but only quite small ones, which earlier were more difficult to
detect. This meteorite has been well preserved due to the very "light"

methods the age of the meteorite is stated to be four billion years. It has
been formed about at the same time as our solar system. This research has been
supported by the theory of the creation of the Widemannstätten figures. The
figures are present in the most of the Gibeon-meteorites, which are classed as
When the Gibeon
octaedrite is sawn, cut, polished and etched, there will be the
lamellae-system, the trigon shaped figures visible on the surface. These figures
has still not been synthetically crated in laboratory environments by Man, and
that is why they prove the authentity of the material. The Widemannstätten figures are
formed in almost zero-gravity conditions and extremely cold temperatures, where
the cooling has been one degree in every one thousand years. The creation of the
figures has lasted alltogether 800 million years. Due to the figures, unique gemstones
can be cut outof the stone.

from Windhoek where there is a large Meteorite collection. All the
newly found pieces are very important to Namibia, and there is
export regulations, which protect the natural cultural treasure.
