Those deposits are called tillites and they’re the material that gets left behind by glaciers.

这些沉积物被称为硅土，它们是 冰川留的物质。

ROSS COEN: They look at the diatoms.

罗斯·科恩：他们观察硅。

These  can be grouped as follows: Phytoplankton – plant-life such as algae  and diatoms that photosynthesise sunlight.

这些可分为以：浮游植物——利用阳光进行光合作用的植物生命，例如和硅。

ELISA BERGSLIEN: Put that all together, where would you find these diatoms, these minerals, that you wouldn't find coral?

ELISA BERGSLIEN：把所有这些放在一起，你会在哪里找到这些硅、这些矿物质，而你找不到珊瑚？

Tiny fossilized skeletons of aquatic creatures called diatoms are swept into the wind and carried westward where they rain down on South America.

被称为硅的水生生物的微小骨骼化石被风吹走并向西飘落在南美洲。

Mr. Bowler says almost half of the oxygen we breathe comes from very small algae called diatoms. These plants live in the part of the water where the sun reaches.

鲍勒说我们呼吸的近一半的氧气来自名为硅的微小，这些植物生活在太阳能抵达的水中。

Those plants and animals that do survive usually reproduce very fast and in great numbers. The single-cell plant, the diatom, can multiply itself into a billion new distoms in one month.

那些生存来的植物和动物通常重新繁衍更快和更多的数。单细胞植物，像硅，能在一个月自己繁衍一百万新的硅。

They're diatoms: photosynthetic, single-celled algae responsible for producing oxygen and helping seed clouds on a planetary scale and with intricately sculpted, geometric exoskeletons made of -- yeah, glass.

它们是硅：光合作用的单细胞，负责产生氧气并在行星范围内帮助种子云， 并具有由——是的， 玻璃制成的复杂雕刻的何外骨骼。

Few objects are more beautiful than the minute siliceous cases of the diatomaceae: were these created that they might be examined and admired under the higher powers of the microscope?

很有物体比硅科的微小硅质外壳更美丽：这些物体是为了在更高倍数的显微镜进行检查和欣赏而创造的吗？

He soon found that mixing nitroglycerine with kieselguhr would turn the liquid into a paste which could be shaped into rods of a size and form suitable for insertion into drilling holes.

他很快发现，将硝化甘油与硅土混合会将液体变成糊状，可以将其塑造成适合插入钻孔的大小和形状的棒。

Some of the critters I found were delightful things like seed shrimp and many more beautiful, geometric diatoms. I then went farther afield to camp out in the Dry Valleys for a couple of weeks.

我发现的一些小动物是令人愉快的东西， 例如种子虾和许多更美丽的何硅。然后我去了更远的地方， 在干谷露营了个星期。
