The Indian micro-brand, Bangalore Watch Company, has also released a line of space themed watches called Apogee that includes a model with the dial sourced from the meteorite.The Indian brand, Titan, uses the meteorite for one sub-dial on its Swiss-made Meteorite by Xylys chronographs. The watch brand Zelos also uses slices of the meteorite as dials and bezel inserts in their watches. Another part of the meteorite is used in the BOLDR Odyssey watch. Ī part of the meteorite is used in the 25-pieces limited Rolls-Royce Tranquility Collection ( Phantom VIII) Controller and in the M850i xDrive Coupé Night Sky Edition by BMW.

Distribution įragments of the Muonionalusta meteorite are held by numerous institutions around the world. One can safely assume then that stishovite formation (in the Muonionalusta meteorite) is connected with an impact event. Clearly, the meteoritic stishovite cannot have formed by isostatic pressure prevailing in the core of the parent asteroid. Stishovite, a high pressure polymorph of SiO 2, is an exceptionally rare mineral.and has only been found in association with a few meteorite impact structures. From the article "First discovery of stishovite in an iron meteorite": For the first time, analysis has proved the presence of a form of quartz altered by extremely high pressure- stishovite, probably a pseudomorphosis after tridymite. It also contains the minerals chromite, daubréelite, schreibersite, akaganéite and inclusions of troilite. New analysis of this strongly shock-metamorphosed iron meteorite has shown a content of 8.4% nickel and trace amounts of rare elements-0.33 ppm gallium, 0.133 ppm germanium and 1.6 ppm iridium. ![]() Slice (across 9.6 cm) of a Muonionalusta meteorite fragment, showing the Widmanstätten pattern. It has a strongly weathered surface covered with cemented faceted pebbles. It was unearthed from a glacial moraine in the northern tundra. ![]() Since landing on Earth the meteorite has experienced four ice ages. It is quite clearly part of the iron core or mantle of a planetoid, which shattered into many pieces upon its fall on our planet. Studies have shown it to be the oldest discovered meteorite impacting the Earth during the Quaternary Period, about one million years ago. The name Muonionalusta is Finnish: it comes from the name Muonio (+ possessive particle -(o)n-) and alusta, which in this context means "a place below", i.e. The Muonionalusta meteorite, probably the oldest known meteorite (4.5653 ± 0.0001 billion years), marks the first occurrence of stishovite in an iron meteorite. It was studied in 1948 by Professor Nils Göran David Malmqvist. ![]() Högbom, who named it after the nearby place Muonionalusta on the Muonio River. The meteorite was first described in 1910 by Professor A. Other fragments have been found in a 25-by-15-kilometre (15.5 mi × 9.3 mi) area in the Pajala district of Norrbotten County, approximately 140 kilometres (87 mi) north of the Arctic Circle. Around forty pieces are known today, some being quite large. The first fragment of the Muonionalusta meteorite was found in 1906 near the village of Kitkiöjärvi. The Muonionalusta meteorite ( Finnish pronunciation:, Swedish pronunciation: ) is a meteorite classified as fine octahedrite, type IVA (Of) which impacted in northern Scandinavia, west of the border between Sweden and Finland, about one million years BCE.
