LOW PRICE!!!MUONIONALUSTA IRON METEORITE!!!Big Block Cut!!!Exquisite Etched Specimen!!!Classification: Iron, IVA!!! Found: 1906!!!Location: Sweden!!!Total Known Weight: Thousands of Kilos!!!Weight: 46.3 grams!!!The Muonionalusta 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.The first fragment of the Muonionalusta was found in 1906 near the village of Kitkiöjärvi. Around forty pieces are known today, some being quite large. 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 .The meteorite was first described in 1910 by Professor A. G. Högbom, who named it "Muonionalusta", after a nearby place on the Muonio River . It was studied in 1948 by Professor Nils Göran David Malmqvist . The Muonionalusta, probably the oldest meteorite known to man (4.5653 billion years), marks the first occurrence of stishovite in an iron meteorite.DescriptionStudies have shown it to be the oldest discovered meteorite impacting the Earth during the Quaternary period, about one million years ago. 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. Since landing here this meteorite has experienced four ice ages. It was unearthed from a glacial moraine in the northern tundra . A strongly weathered surface covered with cemented faceted pebbles leaves no doubt that its sojourn on Earth has been long and dramatic.Composition: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 . It also contains the minerals chromite , daubréelite , schreibersite , akaganéite and inclusions of troilite . 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 . From the article "First discovery of stishovite in an iron meteorite":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.... Clearly, the meteoritic stishovite cannot have formed by isostatic pressure prevailing in the core of the parent asteroid.... One can safely assume then that stishovite formation (in the Muonionalusta meteorite) is connected with an impact event. The glass component might have formed directly as a shock melt....A 2010 study reported the lead isotope dating in the Muonionalusta meteorite and concluded the stishovite was from an impact event hundreds of millions of years ago: "The presence of stishovite signifies that this meteorite was heavily shocked, possibly during the 0.4 Ga [billion years] old breakup event indicated by cosmic ray exposure...."BUYER TO PAY $5 FIRST CLASS SHIPPING ANYWHERE IN THE U.S. OR BUYER TO PAY $15 SHIPPING COSTS TO ANYWHERE ELSE IN THE THE WORLD.
