Meteorite reveals rare irregular crystals

Scientists have found naturally occurring quasicrystals for the second time in a meteorite recovered from eastern Russia, according to a new study in Scientific Reports. Some of the researchers, including the lead author, Luca Bindi of the University of Florence in Italy, reported the discovery of the first natural quasicrystal, a mineral called icosahedrite, in the same meteorite in 2012. The researchers say that both quasicrystals probably formed under the high temperatures and pressures of a violent cosmic collision about 4.5 billion years ago, shortly after the formation of the solar system.
