Description
MORASKO Météorite de fer, coupe d'extrémité avec cohenite - 228 g
Poznan, Pologne

Very rare, end cut with several cohenite inclusions and impact lines

Morasko is a very difficult to acquire meteorite, since for 2 years, its search and collection has been prohibited.

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 into our planet. They are estimated to account for 5.7% of falls.

The Widmanstätten pattern is the result of the intergrowth of taenite and kamacite strips, which are two iron and nickel alloys. In order to produce this pattern, very slow cooling is needed, of at least 1 degree Celsius per million years

At Expometeoritos, we take care of dissemination, talks, workshops, analyses, classification and exhibitions of meteorites.

We are members of:
.- IMCA (International Meteorite Collectors Association) #8187
.- Meteoritical Society

All our pieces are certified and, if the value of a piece is over €300, we also provide its chemical composition analysis, carried out in our facilities by X-ray spectrography.
