The study has also revealed that the Chang'e-6 lithic fragment samples are primarily composed of basalt, breccia, agglutinate, glasses and leucocrate.

研究还揭示，嫦娥六号的石碎片样由玄武、角砾、凝聚物、玻璃和白长石组成。

Percolating into empty cracks and cavities, such as those found in breccias, it creates flowstones.

渗透到空的裂缝和空腔中，例如在角砾中发现的裂缝和空腔，它会产生流石。

The team now reckon the Member 4 breccia formed between 3.4m and 3.6m years ago, over a million years earlier than believed.

该团队现在估计 Member 4 角砾成于 340 万至 360 万年前，比人们认为的早了 100 万年以上。

To test that idea, they directly dated the cave breccias in Members 2 and 4 using cosmogenic nuclide dating, which Dr Granger helped develop.

为了验证这个想法，他们使用格兰杰博士帮助开发的宇宙成因核素测年法，直接对成员 2 和成员 4 中的洞穴角砾了测年。

Using this method Dr Granger and colleagues determined, in 2015, that the breccia in Member 2 is 3.7m years old—1.5m years more ancient than originally thought.

使用这种方法，Granger 博士及其同事在 2015 年确定，成员 2 中的角砾有 370 万年的历史——比最初认为的古老 150 万年。

When a breccia-forming object falls into a cave, it finds itself shielded from cosmic rays, and the steady decay of its existing cosmogenic nuclides can be used to determine how long ago it fell in.

当成角砾的物体落入洞穴时， 它发现自己免受宇宙射线的影响， 并且其现有的宇宙成因核素的稳定衰变可以用来确定它落入洞穴的时间。

In 1912 a man drilling a well for the town water supply reported bringing up a lot of strangely deformed rock, a crystalline clast breccia with a melt matrix, and overturned ejector flap, as it was later described in an official report.

1912 年，一名男子为城镇供水系统钻了一口井，报告说发现了许多奇怪变的石、带有熔融基质的结晶碎屑角砾和翻转的喷射器瓣，后来在官方报告中对此了描述。
