Then we transitioned from that crater floor into the sedimentary deposits and now we're here in sandstones, conglomerates, mud stones, the kinds of rocks that are deposited by flowing water.

然后我们从火山口底部过渡到沉积沉积，在我们在这里看到了砂岩，砾岩，泥石，这些是由流水沉积的岩石。

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，嫦娥六号的岩石碎片样本主要由玄武岩、角砾岩、凝聚、和白长石组成。

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

渗透到的裂缝和腔，例如在角砾岩的裂缝和腔，它会产生流石。

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，报告说了许多奇怪变形的岩石、带有熔融基质的结晶碎屑角砾岩和翻转的喷射器瓣，后来在官方报告对此进行了描述。

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

该团队在估计 Member 4 角砾岩形成于 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的宇宙成因核素测年法，直接对成员 2 和成员 4 的洞穴角砾岩进行了测年。

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 的角砾岩有 370 万年的历史——比最初认为的要古老 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.

当形成角砾岩的体落入洞穴时， 它自己免受宇宙射线的影响， 并且其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。
