Rocks like plagioclase and olivine that contain calcium and magnesium naturally absorb carbon dioxide to become limestone or dolomite.

比如含有钙和镁的斜长石和石可以自然吸收二氧化碳转变成石灰岩和白云石。

Some have green or orange crystals of a mineral called Olivine embedded in a web of metal.

一些有着绿色或橙色的矿物晶体的叫做石，它们嵌在金属网。

Olivine is quite common here on Earth but it's largely found inside the planet.

石在地球上很常见，但它主要存在于地球内部。

The plagioclase content of the Chang'e-6 samples is significantly higher than that of the Chang'e-5 samples, while their olivine content is significantly lower.

嫦娥六号样本的斜长石含量显著高于嫦娥五号样本，而其石含量则显著较低。

Olivine is a type of rock that can actually be found here on Earth, for instance  in parts of Australia.

石是一种岩石， 实际上可以在地球上找到，例如在澳大利亚的部分地区。

See, tiny green crystals made of a mineral called olivine are falling down on this star from its surrounding clouds of gas.

看，由一种叫做石的矿物制成的微小绿色晶体从周围的气体云中落在这颗恒星上。

Unlike sedimentary rocks, which are made by particles of sand and other  detritus slowly accumulating on top of each other over time, an igneous rock like Olivine  is formed by the cooling of magma.

沉积岩是由沙子和其他碎屑颗粒随着时间的推移慢慢堆积而形成的，而像石这样的火成岩是由岩浆冷却形成的。
