" 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，因为石灰方解石已经渗漏成了小钟乳石，”他入墓室，并在节目使用激雷达（和距）行了索。

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

Their calcite exoskeletons made for hardy fossils that would remain intact for hundreds of millions of years to come.

它们方解石甲壳形成了坚韧化石，在接下来数亿年都维持完好。

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.

你现在看到例子是方解石，当你看到重影时， 是因为一种偏振以不同速率被弯曲， 而另一种偏振则不是。

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.

大小介于一粒米和一颗小利马豆之间，最近发现表明其含有方解石和磁铁矿晶体碎片。

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.

方解石是两者更稳定一种，随着时间推移不易溶解，因此大多数软体动物壳都有一层坚固方解石外层。

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