For instance, zircons and a few grains of quartz have been found on the moon , which never developed a granitic, continental-style crust .

例如，在月球那样绝不会有花冈岩或大陆型态地壳出现的地方，仍可找到锆石及少许的石英结晶。

3

These findings imply that the zircons were once plentiful and came from a widespread source region , possibly a continental landmass .

这些发现暗示，锆石的数量曾经很丰富，而且源自一片分布很广的地区，例如一个大陆陆块。

4

The analysis results show that there are two types of zircons from the Danzhu granodiorite: magmatic zircon and metamorphic zircon .

研究结果表明，该花岗闪长岩中存在两种不同类型的锆石：岩浆锆石和变质锆石。

"These zircons have been absolutely hammered, " Rasmussen says .

拉斯姆森表示：“这些锆石绝对经过一番摔打。”

6

The distribution of ancient zircons provided additional evidence .

古锆石的分布也提供了其他的证据。

7

Zircons in the rocks were exposed to the same conditions .

这些岩石中的锆石也暴露在同样的环境中。

8

Today , Earth teems with thousands of kinds of minerals , from agates to zircons .

今天，地球充满从玛瑙到锆石等成千上万种矿物。

9

Found in rocks throughout Earth's crust, zircons are some of the oldest bits of mineral on Earth .

广泛分布于地壳各处岩石中的锆石是地球上最古老的矿物之一。
