TheAletai meteorite, previously also known as theArmanty meteoriteorXinjiang meteorite, is one of the largest knowniron meteorites, classified as a coarseoctahedritein chemical group IIIE-an.[b]In addition to many small fragments, at least five main fragments with a total mass over 74 tonnes have been recovered, the largest weighing about 28 tonnes.[1]
Among the irons of the Aletai meteorite, three pieces can be distinguished, which at the moment apparently occupy the 5th, 6th and 9th places among thelargest meteorites found on Earth.[3]The correspondingstrewn fieldalong its long axis is at least 430 km (and presumably even larger). It is by a margin the largest meteorite debris scattering field found on the planet, believed to be due to its unique stone skipping-like trajectory.[
