They compared that core with another from Arizona, embedded with zircons.

他们将块岩心与亚利桑州一块嵌有石的岩心进行了对比。

And that's where a resilient little mineral called zircon comes in.

就有弹性的石来源。

But zircon also has two things quartz doesn't: zirconium, which gives it its name, and small traces of radioactive uranium.

，它名字的由来，还有少量放射性铀的痕迹。

In this case, Ramezani was dating tiny zircon crystals embedded in a fossil bed in Patagonia, near the southern tip of South America.

在本研究中，Ramezani 一直在北美南段附近的巴塔哥尼亚，里化石床中镶嵌的微型英石的年代。

There is too much money in palm oil, as well as timber, coal, gold, zircon and the forest's other vegetable and mineral riches.

棕榈油有很大的价值, 森林中的木材、煤炭、黄金、石、其他蔬菜和丰富的矿产也如此。

In this case, Ramezani was dating tiny zircon crystals, in fact, in a fossil bed in Patagonia, near the southern tip of South America.

在个案例中，拉米扎尼在靠近南美洲南端的巴塔哥尼亚的化石层中微小的石晶体的年代。

So despite earth's best efforts to hide its age from us, uranium-lead dating of little bits of zircon tells us our planet formed at least 4.4 billion years ago.

所以尽管地球尽最大的力对我们来掩藏它的年龄，少量铀铅的结合在石内，告诉我们，我们的星球至少在 44 亿年前形成。儿。

And one of the oldest terrestrial minerals ever found, quite possibly the oldest piece of the earth we know of, happens to be a very lead-filled grain of zircon found embedded in sandstone in Western Australia.

有史以来发现的最古老的陆地矿物之一，很可能我们所知道的地球上最古老的一块，恰好嵌入澳大利亚西部砂岩中的非常铅含量的石颗粒。

Which is weird, because lead isn't similar to zirconium, and so would never have ended up in a zircon crystal on its own, so the more lead you find in a zircon crystal, the older you know it is.

就奇怪了，因为铅与不相似，所以绝不会单独出现在石晶体中，所以在石晶体中发现的铅越多，它的年代越久远。
