This book describes the discovery of quasicrystals (icosahedral and decagonal) in an extraterrestrial rock from the Koryak Mountains of Far Eastern Russia. After a decade-long search for a natural quasicrystal, this discovery opened a new avenue in mineralogy and crystallography that could lead to further discoveries in geoscience, astronomy, condensed matter physics, and materials engineering. For the first time, minerals have been discovered that violate the symmetry restrictions of conventional crystallography. The natural occurrence of such crystals was unexpected, involving previously unknown processes. The fact that the quasicrystals were found in a meteorite formed in the earliest moments of the solar system means these processes have been active for over 4.5 billion years and have influenced the composition of the first objects to condense around the Sun. Finding quasicrystals formed in these extreme environments also informed the longstanding debate concerning the stabilityand robustness of quasicrystals. Recent shock experiments lend support to the hypothesis that the extraterrestrial quasicrystals formed as a result of hypervelocity impacts between objects in the early Solar system, and that they are probably less rare in the Milky Way.
Rezensionen / Stimmen
"The book is currently the only available textbook on natural quasicrystals. Overall, it includes both basics and advanced discussions covering descriptive, experimental, and theoretical mineralogy, nevertheless is concise and written in plain sentences. . This book is strongly recommended to both experienced mineralogists and petrologists, as well as beginners, and in particular, for the high-pressure mineral physics and meteoritics researchers." (Naotaka Tomioka,American Mineralogist, Vol. 106, 2021)
