So-called natural quasicrystals, found in Russian Koryak Mountains (Chukotka), arrived at our planet from the open space.
      
      Such is the conclusion of scientists who have studied the unusual crystals found in Russia; it is explained in the article published on Tuesday in the magazine Proceedings of the National Academy of Sciences.
      
      Quasicrystals almost never occur in nature of the Earth. They are called so because their crystal lattice has not only a periodic structure, but also includes axes of symmetry of different levels, the existence of which earlier contradicted to notions of crystallographers.
      
      Khatyrkite was found back in 1979 by the Russian geologist Valery Kryachko in the course of examining the channel of River Khatyrka in the area of Koryak Mountains in Chukotka.
