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

这有利于撞击的形成，因地幔热柱搬运的具有更深的起源。

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的岩心进行了对比。

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的矿物质。

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

在那项研究中，研究人员检查了晶体中含有多少铀和铅原子。

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

这就是有性的来源。

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

赫克指出，是一种非常坚固的矿物质，可以“在岩风化过程中幸存下来”。

Zircon dating helped scientists figure out that these separate mountain ranges used to be one.

测年助学家确定，这些独立的山脉曾经是连一体的。

And remember, zircons are also used in radiometric dating.

请记住，也用于辐射 测年。

If zircon crystals are hiding in there, inside the rock they formed in.

如果晶体藏匿其中，即它们最初形成的岩内部。

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

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

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

据信，是在撞击后月球表面熔化后冷却时形成的。

And zircon is both of those things.

而兼具这两种特性。

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

，这是它名字的由来，还有少量放射性铀的痕迹。

You can think of zircon kinda like an hourglass.

你可以把想象成一种类似沙漏的物体。

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、、其他蔬菜和丰富的矿产也是如此。

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

在本研究中，Ramezani 一直在北美南段附近的巴塔哥尼亚，测定那里化床中镶嵌的微型英的年代。

Ancient zircons are completely rewriting that history.

古老正彻底改写这段历史。

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，在海水中发现的氧-18和氧-16的比率比高0.5%的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.

在这个案例中，拉米扎尼在靠近南美洲南端的巴塔哥尼亚的化层中测定微小的晶体的年代。

A beam, a few thousandth of a millimeter wide, is fired at the zircon crystal, blasting away this cloud of atoms.

一道宽度仅千分之几毫米的光束射向晶体，瞬间将其中的原子云轰散。
