Fifteen pieces of the Kainsaz meteorite were seen to fall near Kainsaz, Muslyumovo, Tatarstan on September 13, 1937.[1] The largest weighed 102.5 kilograms (226 lb), the total weight was ~200 kilograms (440 lb).[2][3] As of January 2013[update] pieces were on sale for ~US$100/g.[2] Kainsaz is the only observed fall in Tatarstan.[3]
History
A fireball was observed which left a dust train and broke into fragments during flight in a series of detonations that were heard up to 130 kilometres (81 mi) away.[1] The strewn field of 40 by 7 kilometres (24.9 mi × 4.3 mi) was oriented SE-NW with the largest stone falling at the NW end,[1] the smallest (the size of a nut) near the village of Kosteevo at the SE end.[1]
Mineralogy
Most of the chondrules (90 %) are either droplet (39 %) or lithic (61 %). The remaining 10 % are barred olivine, radial pyroxene, cryptocrystalline, glassy, sulfide-metal, micro-poikilitic and complex chondrules.[4]
