This favours impact formation, as zircons transported by mantle plumes would have more profound origins.

这有利于击的形成，因为地幔热柱搬运的锆石具有更深的起源。

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

这就有弹性的锆石来源。

The team said the crystals contained a mineral called zircon.

研究小组表示，这些晶体中含有一种名为锆石的矿物质。

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

他们将这块岩心与亚利桑那州一块嵌有锆石的岩心进行了对比。

Heck noted that zircon is a very strong mineral that can " survive the breakdown of rocks during weathering."

赫克指出，锆石一种非常坚固的矿物质，可以“岩石风化过程中幸存下来”。

In that study, researchers examined how many atoms of uranium and lead were contained in the zircon crystals.

那项研究中，研究人员检查了锆石晶体中含有多少铀和铅原子。

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

锆，这它名字的由来，还有少量放射性铀的痕迹。

The zircon is believed to have formed when the lunar surface cooled after being in a melting state after the crash.

据信，锆石击后月球表面熔化后冷却时形成的。

And remember, zircons are also used in radiometric dating.

请记住，锆石也用于辐射 测年。

Analyses of their constituent zircons could well provide valuable supporting evidence that Earth's continents owe their existence to bodies from outer space.

对其构成的锆石的分析很好地提供有价值的佐证，证明地球大陆的存应归功于来自外太空的天体。

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, 这森林中的木材、煤炭、黄金、锆石、其他蔬菜和丰富的矿产也如此。

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

本研究中，Ramezani 一直北美南段附近的巴塔哥尼亚，测定那里化石床中镶嵌的微型锆英石的年代。

Zircons whose ratio of oxygen-18 to oxygen-16 is 0.5% higher than found in seawater, for example, would have originated far below Earth's surface.

例如，海水中发现的氧-18和氧-16的比率比高0.5%的锆石可能起源于地球表面以下很远的地方。

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

这个案例中，拉米扎尼靠近南美洲南端的巴塔哥尼亚的化石层中测定微小的锆石晶体的年代。

But the authors will also need to explain why zircons previously found at other, even older, sites do not display the same telltale signature of impact.

但作者还需要解释，为什么之前其他更古老的地点发现的锆石没有显示出相同的击迹象。

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，少量铀铅的结锆石内，告诉我们，我们的星球至少 44 亿年前形成。这儿。

That speed showed that the samples were made of zircon, and zircon is one of the oldest known solids, meaning the moon must be the same age, 4.46 billion years old.

这个速度表明样本由锆石构成的，而锆石已知最古老的固体之一，这意味着月球的年龄也一定44.6亿岁。

There's also other evidence from meteorites that suggests the earth is even older, but at bare minimum, this zircon lets us say with confidence that the earth is literally older

陨石还有其他证据表明地球更古老， 但至少，这颗锆石让我们自信地说， 地球确实更老了。

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锆石颗粒。

Most of the broad summit is comparatively level and thick sown with crystals, quartz, mica, hornblende, feldspar, granite, zircon, tourmaline, etc., weathered out and strewn closely and loosely as if they had been sown broadcast.

宽阔的峰顶大部分较为平坦， 密布着水晶、石英、云母、角闪石、长石、花岗岩、锆石、电气石等，经风化后，密布、松散， 犹如播种。
