The stone was of a type called a carbonaceous chondrite.

The rocks are carbonaceous chondrites, one of the rarest types of meteorites, rich in carbon.

But only the carbonaceous chondrites contain water - as well as lots of carbon, if you couldn't tell from their name.

你从它称中也可以得知它们带有很多碳， 它们之所以带有水是因为它们是在太阳雪线以外形成。 此外它们水中带有氘比例。
