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

比如含有钙镁的斜长榄可以自然吸收二氧化碳转变成灰岩白云。

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含量显著高于嫦娥五号样本，而其榄含量则显著较低。

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榄，它们嵌在金属网里。

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

榄在地球上很常见，但它主要存在于地球内部。

Peridot is a high-quality version of the mineral olivine.

榄是矿物榄的一种高品质变体。

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

看，由一种叫榄的矿物制成的微小绿色晶体从周围的气体云中落在这上。

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

榄是一种岩， 实际上可以在地球上找到，例如在澳大利亚的部分地区。

That stuff is olivine, basically tiny specks of peridot.

那东西是榄，基本上就是些小粒的榄。

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.

沉积岩是由沙子其他碎屑粒随着时间的推移慢慢堆积而形成的，而像榄这样的火成岩是由岩浆冷却形成的。

If you go to the southernmost point of the Big Island and go up the east coast about one mile, you will find the Green Sand Beach, which is an entire beach made out of olivine, aka peridot.

若你前往大岛的最南端，并沿着东海岸行进约一英里，便能发现绿沙滩——这片海滩完全由榄（又称榄）构成。

Its mission is to analyse the composition of olivine  rocks near the Shioli Crater, some 200 miles south of the Sea of Tranquility, where  Neil Armstrong took his famous " small step" .

其任务是对宁静海南部约200英里处的Shioli陨坑附近的榄岩进行成分分析，这一地点正是尼尔·阿姆斯特朗迈出其着名“一小步”的地方。
