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橄榄石，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.

比有钙和镁的斜长石和橄榄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，橄榄石。

Peridot. - Is that what it's called?

橄榄石 -原来叫这个名？

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

橄榄石在地球上很常见，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量显著高于嫦娥五号样本，而其橄榄石量则显著较低。

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

橄榄石是一种岩石， 实际上可以在地球上找到，例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，由一种叫做橄榄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，而像橄榄石这样的火成岩是由岩浆冷却形成的。
