carbonaceous chondrite

(C chondrite)
(stony meteorites with carbon compounds showing no melting)

Carbonaceous chondrite is a category of meteorite, specifically one that is stony rather than metallic, that shows no signs of melting, and that includes carbon compounds. They represent only about one in twenty meteorites. Various subclasses include significant water and/or amino acids, or show very close correlation to the makeup of the solar photosphere. They have been theorized as Earth's source of water.
