Sikhote-Alin meteorite is in the top ten largest meteorites world, and a number of features makes this meteorite unique - for example, when the overall homogeneity of chemical composition, it does not represent a single crystal, a complex of many randomly oriented crystals, "not related" [Fesenko, 1978], and that probably led to the disintegration of many parts.

This is a classic example of meteorite falls. Were extremely favorable time and place of the fall, perfect weather, and even divide, kept a picture of destruction as much as possible. Place the fall of the meteorite was discovered the next day, but after two weeks of the first investigators were at the scene of incidence.

A large number of substances made it possible to virtually any testing without risk to spend too much. Therefore, a meteorite thoroughly investigated. On it is written, at least three monographs, and hundreds of scientific articles. Now everything is more or less the major museums of the world have samples of the Sikhote-Alin meteorite. In addition to the recorded 27 tons of collected materials, a lot of samples went to the country and from time to time vyplyvayut in unexpected places.

Snow has been sealed and the resulting solid now freely withstand rights. Among this chaos ziyali craters and the crater. The largest crater had a diameter of 26 meters and a depth of 6 m. The huge cedar trees felled with roots lying radially around the crater. Geologists have found about 30 crater and craters, and a plan of their location. In one of the craters of broken rocks they collected meteorite fragments.

In the area of impact has been a special expedition to the end of April reached the place of work. Expedition led by Academician VG Fesenko. To help military expedition Primorsky district had been allocated a unit of deminers. The expedition conducted a detailed survey of the crash site, interviewed witnesses, completed teodolitnuyu filming location and has collected several tons of individual copies and fragments of meteorite rain.
