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矿物晶体叫石，它们嵌在金属网里。

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

比如含有钙和镁长石和石可以自然吸收二氧化碳转变成石灰岩和白云石。

Instead, Perseverance had discovered the igneous  rock, Olivine.

相，毅力号发现了火成岩，石。

Peridot. - Is that what it's called?

石 -原来叫这个名？

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.

嫦娥六号样长石含量显著高于嫦娥五号样，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，由一种叫石矿物制成微小绿色晶体从周围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推移慢慢堆积而形成，而像石这样火成岩是由岩浆冷却形成。
