Additional Information |
Németh P, Garvie LAJ, Salzmann CG (2023) untersuchen Material von der Typlokalität und stellen fest, dass "In conclusion, Canyon Diablo lonsdaleite is not a discrete phase, but instead is a nanocomposite of disordered c/h stacked diamond and diaphite." Damit wäre Lonsdaleit kein eigensändiges Mineral. Eine Diskreditierung durch die IMA wird in dem Artikel jedoch nicht angesprochen. |
