A new polymorph of carbon, hexagonal diamond, has been discovered in the Canyon Diablo and Goalpara meteorites. This phase had been synthesized recently under specific high-pressure conditions in the laboratory. Our results: provide strong evidence that diamonds found in these meteorites were produced by intense shock pressures acting on crystalline graphite inclusions present within the meteorite before impact, rather than by disintegration of larger, statically grown diamonds, as some theories propose.
一种新的碳多形体——六方金刚石，已在 Canyon Diablo 和 Goalpara 陨石中被发现。这种相最近在实验室中特定的高压条件下被合成。我们的研究结果：强烈地证明了这些陨石中发现的钻石是由冲击压力作用于陨石中存在的结晶石墨包裹体而产生的，而不是如一些理论所提出的那样，由较大的、静态生长的钻石的解体产生的。
