INTRO: A team of researchers has discovered a new mineral accidentally created by a lightning strike or a downed power line in a wind-created dune in the Sand Hills of north central Nebraska. The discharge produced extreme temperatures (over 1,710 degrees) that led to the formation of a fulgurite, a tube of fused and melted sand along with traces of melted conductor metal from the power line.
Within the fulgurite was found a dodecagonal quasicrystal, an "impossible crystal" previously not found occurring naturally on Earth.
Until a few years ago quasicrystals were only hypothesized by physicist. Unlike classic crystals of minerals, quasicrystals are composed of equally spaced atomic layers, but the arrangement of the atoms doesn't repeat like in a classic crystalline structure. While crystals, according to the classical crystallographic rules, can possess only two-, three-, four-, and six-fold symmetries, quasicrystals can display a higher symmetry... (MORE - details)
