The discovery of icosahedrite, the first natural quasicrystal, and the subsequent discovery of two other types of quasicrystals challenged the conventional wisdom. Icosahedrite was found to be formed naturally in CV3 chondrites that comprised the primordial material of our Solar System. So, it is not impossible to form it outside the laboratory. Since it has only been reported in one CV3 chondrite to date, one cannot draw precise quantitative conclusions.

准晶体在宇宙中真的如此罕见吗？

第一种天然准晶二十面体的发现，以及随后发现的另外两种准晶对传统智慧提出了挑战。二十面体被发现是在 CV3 球粒陨石中自然形成的，CV3 球粒陨石构成了我们太阳系的原始材料。所以，在实验室之外形成它也不是不可能的。由于迄今为止仅在一颗 CV3 球粒陨石中报道过它，因此无法得出准确的定量结论。
