As it builds up, so the calcite forms decorations that hang from the ceiling, stalactites.

Made of calcite rods, the same stuff that forms limestone, they constituted the earliest visual systems known.

Using special proteins, mollusks can produce two crystal structures out of CaCO3: calcite and aragonite.

Plus, they were covered from their rounded heads to their many segmented feet in an exoskeleton made of calcite and chitin.

此外，它们从圆圆的头部到多节的脚部都覆盖着由方解石和几丁质构成的外骨骼。

Calcite is the more stable of the two and less prone to dissolving over time, so most mollusk shells have a sturdy outer layer of calcite.

方解石是两者中更稳定的一种，随着时间的推移不易溶解，因此大多数软体动物的壳都有一层坚固的方解石外层。

Between the size of a grain of rice and a small lima bean, a recent discoveries have found calcite and magnetite crystals chips in it or fragments.

He dimly recalls the subtle variations in texture, the distinctive calcite deposits that run up the length of the wall, stretching up, up, to a small window in the rock.

他模糊地记得那些细微的质地变化，沿着墙面延伸的特有的方解石沉积物，一直向上伸展， 直到岩石上的一小扇窗户。

The example you're looking at right now is calcite, and when you're seeing double, it's because light with one polarization is getting bent at a different rate than light with the other polarization.

你现在看到的例子是方解石，当你看到重影时， 是因为一种偏振的以不同的速率被弯曲， 而另一种偏振的则不是。

" The inside looks like a crystal cave because the limestone has leaked calcite into little stalactites, " says Lin, who entered the tomb and used lidar (light detection and ranging) to explore it on the show.

“里面看起来就像一个水晶洞，因为石灰岩中的方解石已经渗漏成了小钟乳石，”他进入墓室，并在节目中使用激雷达（探测和测距）进行了探索。
