DEF

A diverse class of chondrites (one of the two divisions of stony meteorites), important because of the insights they provide into the early history of the solar system.

CONT

[These chondrites] comprise about 3 percent of all meteorites collected after being seen to fall to Earth. Carbonaceous chondrites are subdivided into six well-established groups—CI, CM, CV, CO, CR, and CK—based on their bulk chemistry, petrology, and oxygen isotopic compositions.

CONT

Carbonaceous chondrites show very little metamorphism but display evidence of chemical alteration by water, which continued after their formation, suggesting the parent body was rocky material mixed with ice. They contain a varied suite of organic compounds ... and a high content of inert gases.
