The piece of this lot is a rust fragment in the shape of a crust and that covers many of the large meteorites of this fall.
The Muonionalusta is a meteorite classified as fine octaedrite, type IVA (Of), which hit the North of Scandinavia, west of the border between Sweden and Finland, circa one million years before our era.
The first fragment of Muonionalusta was discovered in 1906 near the village of Kitkiojarvi. About forty pieces are known today, some of them quite large. Other fragments were found in a 25 x 15 km area in the Pajala district in the county of Norrbotten, at about 140 km north of the Arctic polar circle.
The meteorite was described for the first time in 1910 by Professor A.G. Högbom, who named it ‘Muonionalusta’, in reference to a place near the Muonio river. It was studied in 1948 by Professor Nils Göran David Malmqvist. The Muonionalusta, probably the oldest known meteorite (4.5653 billion years) marks the first appearance of stishovite in an iron meteorite.
