A chondritic meteorite discovered in Antarctica.
The largest meteorite ever discovered weighs 60 tonnes and was found in Namibia.
However, s often still have the primordial solar system abundances of these elements.
CAI: Calcium-aluminum-rich inclusions (CAIs) are found in chondritic meteorites. CAIs are primitive materials that formed in the solar nebula before the planets formed.
Primitive s (and presumably their asteroidal parents) still have the primordial solar system abundances of these elements.
A Type I carbonaceous chondritic meteorite that fell in France in 1864 and that has recently been found to contain amino acids. [H76]

There he could see that it was a -- a stony meteorite. This one contained numerous metal grains making it an H chondrite. The rusty weathering told Hildebrand the meteorite had fallen on the prairies thousands of years before.
PETROLOGIC TYPE - Measure of the degree of aqueous alteration (Types 1 and 2) and thermal metamorphism (Types 3-6) experienced by a chondritic meteorite. Type 3 chondrites are further subdivided into 3.0 through 3.9 subtypes.
Asteroidal dust resembles carbonaceous s, and cometary dust resembles interstellar grains, which can include the elements: silicates, polycyclic aromatic hydrocarbons, and water ice.
type are the most common variety and are usually found in the outer regions of the asteroid belt. They have very dark and neutral-colored surfaces, and are probably of carbonaceous composition similar to primitive carbonaceous chondritic meteorites.
