隕石拍賣 (Meteoriten Haus Collection)

来自美国亚利桑那州保存完好的 Barringer Crater 的 Canyon Diablo 隕石蚀刻切片

这块 Canyon Diablo 隕石在撞击时经历了极强的冲击。因此威德曼斯坦图样几乎被抹去，Kamacite 在巨大的压力下转变为 Cohenite，并伴有石墨夹杂。

1891年，直径约1180米的 Meteor Crater 及其周围的铁质块体的陨石起源已被科学界认可。

土地所有者 Barringer 先生多年来试图定位在坑底下形成此陨坑的陨石块。

如今我们知道，陨石大多在爆炸中蒸发，形成了这个陨坑。含铁的凝聚滴，即所謂的球粒（spherules），已在陨坑周围发现，证实了大部分陨石已蒸发。

尽管如此，在陨坑周边区域仍发现约30吨的铁陨石。

This canyon diablo meteorite was highly shocked at impact. So the Widmanstätten pattern are nearly wiped out, the Kamacite turned into Cohenite by enormous  pressure. With Graphite inclusion

In 1891 the meteoritic origin of the 1180 m wide Meteor Crater and the iron masses around have been scientifically accepted.
Mr. Barringer, owner of the land, tried to locate the meteorite mass which has formed the crater, under the crater floor , for decades. Today we know that the meteorite mostly vaporised by the explosion forming the crater. Iron containing condensed droplets ,so call spherules, have been found around the crater and are confirming the fact that most of the meteorite vaporised. Never the less , 30 metric tons of iron meteorites have been found in the  crater surrounding area.
