Carbonaceous Chondrite:
Carbonaceous chondrite is any stony meteorite or asteroid containing material associated with life (e.g., hydrocarbons, amino acids, and forms resembling microscopic fossils) and for which some researchers have postulated an ...

Carbonaceous chondrites make up less than 5% of the chondrites that fall on earth.
So-called carbonaceous chondrites are especially fertile reservoirs of stardust. Each stardust grain existed before the earth was formed. The meteorites have preserved the previously interstellar stardust grains since that time.

Perhaps the most interesting type of meteorite is the CI carbonaceous chondrite. Strictly speaking, one could legitimately question why such meteorites are called chondrites at all inasmuch as they do not contain chondrules.
Those of the C1 carbonaceous chondrites resemble solar material with volatile elements partially removed. 3. The terrestrial bulk abundances are inferred from crustal abundances and earth models.
C-type, includes more than 75% of known asteroids: extremely dark (albedo 0.03); similar to carbonaceous chondrite meteorites; approximately the same chemical composition as the Sun minus hydrogen, helium and other volatiles; ...
One of the rare varieties of these is known as the carbonaceous chondrite, an carbon rich object thought to originate from c-type asteroids. The neat thing about these is that some have been found to contain things like water and amino acids.
A meteorite of the type known as a carbonaceous chondrite, which fell in France on Mar. 15, 1806, and was later examined by Jöns Jakob Berzelius.
Primitive meteorites, in particular carbonaceous chondrites, contain millimetre to centimetre-sized calcium-aluminum-rich inclusions (CAIs) and chondrules, molten or partially molten droplets that become bound up in the asteroid.
Although classified as carbonaceous, Ceres reflects roughly 10 percent of the sunlight that strikes it ("albedo") and so is not as dark as other low-density asteroids called carbonaceous chondrites, which have albedos of around three to five percent.
It is also possible to find unusual isotopes such as magnesium-25, in small samples of material less than a millimetre in diameter, between the grains in the meteorites called carbonaceous chondrites.
Three-quarters of the asteroids visible from earth, including Ceres, belong to the C type, which appear to be related to a class of stony meteorites known as carbonaceous chondrites.
Carbonaceous chondrites are the most primitive meteorites--primitive in a chemical way. For example, the CI group of carbonaceous chondrites are closest in composition to the photosphere (visible surface) of the Sun.
They are similar to carbonaceous chondrite meteorites and exhibit about the same chemical composition as the sun minus its volatiles. About 17% are S-type asteroids, which are brighter, with an albedo of 0.10 to 0.22.
It is similar to the C-type (blackish carbonaceous chondrite) asteroids that exist in the outer asteroid belt.
Comets are icy planetesimals usually from 1 to 50 km across and containing bits of fragile dust resembling carbonaceous chondrite material.
