Number four, also an iron oxide spherule.

第四， 也是氧化铁球体。

But at any event, in Stein Jacobson's lab, we studied the chemical composition of those spherules, and we found that 80% of them belong to materials from the solar system that was seen before, but then 20% look different.

无论如何， 在斯坦·雅各布森的实，我们研究了这些球的化学成分，发现其中80%的物质属于已知的太阳系材料，但剩下的20%则显得与众不同。

After the Chicxulub impact, the spherules settled on the sea floor within minutes.

希克苏鲁大碰撞后，小球体几分钟内便落到海底。

So, a lot of what we found and what Jon says he has found were iron oxide spherules.

所以，我们发现的很多东西以及乔恩说他发现的很多东西都是氧化铁球。

It looked as if the world's forests had spontaneously ignited as the rain of spherules heated the atmosphere by up to a thousand degrees centigrade.

看起来好像是从大气中落下的小球体雨，带着1000℃的高温自动点燃了全世界的森林。

He says glassy spherule, with a small metal bead.

他说是玻璃球体， 带有一个小金属珠。

In outer space the vapour condensed into tiny droplets which fell back all over the earth as white hot spherules.

在外太空，它们凝缩成微小的熔珠，它们落满整个球，变成白热的小球体。

So, number two is an iron oxide spherule.

所以， 第二个是氧化铁球体。

These were the spherules just discovered by Doctor Keller.

它们就是Keller博士发现的小球体层。

Number five, iron oxide spherule. Number six, iron oxide spherule.

第五， 氧化铁球体。第六， 氧化铁球体。

On top of the spherules, there seemed to have been a period of normal sedimentation, eight metres of mud had built up.

小球体层上面似乎有一个正常沉淀的时期，堆积了8米厚的泥沙。

They were excited because these spherules were eight metres below where any had been found before.

他们激动是因为这些小球体所在的位置比之前找到的方低了8米。
