· 400 million years ago the Earth was in the initial stages of formation of Pangea (Supercontinent, "All Earth"). The meteorite heated to the melting point due to friction with the atmosphere, and in the form of a fireball, after hitting the earth, exploded.



The initial diameter of the meteorite is 7km, the speed of fall is more than 10 km/s.



· The energy during the explosion - 10k times exceeded the total capacity of all the world's nuclear weapons stockpiles.



· The magnitude of the pressure was millions of atmospheres, the temperature was over 3000 degrees.



· The solidified upon cooling melts crust is the impact and it assimilated meteorite substance.



· In the Illinetsky crater, the content of nickel, iridium, cobalt in the proportions of meteorite rocks is higher than that of the earth. Impact diamonds were first found here in 1974. This is the second crater on Earth where was found these gems and the world's largest agate. According to scientists, the nucleus of the meteorite in Illinetsky crater lies approximately 700 meters deep.

· At the base of the crater are gneisses and blacks, leucocratic pink granites and pegmatites, as well as more rare types of rocks, which are represented by amphibolites. on the modern erosion surface, loose Quaternary deposits are deposited directly on the rocks of the coptogenic complex and the crystalline base complex.
