Kainsaz meteorite
In Kainsaz is an observed meteorite fall from September 13, 1937, 14:15 clock near the Kainsaz kolkhoz, Muslyumovo District, Tatarstan, Russia.
After a visible within a radius of 80 km fireball fell to a 40 km stretch between Kastiljowa in the southeast and to the northwest Kainsaz at least 40 individual masses with a total weight of more than 215 kg. According to witnesses, the case was followed by five or six loud explosions. The real ball of fire and its smoke trail could not be seen from the case of area.
The elliptical strewn field was visited a few days after the fall of the Russian scientist AS Selivanov, ensure the masses of the 15 - Kainsaz case the onset of winter and could bring the Mineralogical Museum Fersman Moscow. Among these was the 102 kg vast bulk of the case, which is now on display still in Moscow. Other discoveries made Selivanov few hundred meters southeast Kainsaz ( a 53 kg mass ) in Tash- Elga ( a 27.5 kg mass ) and at Krasny Yar ( a 22- kg mass ). The impact wells in all cases reported to the diameter of the meteorite and were each about as deep as the largest vertical extent of the particular composition.
The Kainsaz meteorite belongs to the rare group of carbonaceous chondrites. The mineralogical- petrographic analysis revealed a C03.2 - type with a shock stage S2 and a degree of weathering of W0. The coordinates of the case today with 55 ° 26 '0 "N, 53 ° 15' 0 " O55.43333333333353.25Koordinaten: indicated 55 ° 26 '0 "N, 53 ° 15' 0" E ( the site where the main mass ).
The remote and little explored stray field of the meteorite fall came during the Second World War into obscurity and was only rediscovered in 2000 by Russian Meteoritenprospektoren. This found that the angle of the central axis of the stray field was actually 39 ° and not 47 ° as it was recorded in Selivanovs. Overall, more than 32 other individuals and fragments with masses of 50 g to 2 kg were found in campaigns from 2000 to 2007. The German meteorite researcher Svend Buhl participated in the campaign in 2005, in part, collected and translated eyewitness reports as well as passages from Selivanovs records and published the current state of research of the stray field in an article for the Meteorite Magazine.
Kainsaz was not published until today in the Meteoritical Bulletin of the Meteoritical Society, but is officially recognized by the Meteoritical Society. Both the Data Base of MetBull and the Catalogue of Meteorites lead Kainsaz as observed meteorite fall.
