A chondritic meteorite discovered in Antarctica.
The largest meteorite ever discovered weighs 60 tonnes and was found in Namibia.
However, chondritic meteorites 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 chondritic meteorites (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 chondritic meteorite -- 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 chondritic meteorites, 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.
