ACHONDRITES


about 7% of all known meteorites. There are many different types:

HOWARDITES, EUCRITES, DIOGENITES, OLIVINE-DIOGENITES:
Fragments of the crust of a differentiated asteroid, most likely Vesta.

UREILITES:
primitive achondrites, rich in carbon, and occasionally nano-diamonds.

AUBRITES:
Contain minerals unknown on Earth.

ANGRITES:
one of the rarest, the origin is still being argued.

BRACHINITES, LODRANITES, ACAPULCOITES, WINONAITES:
Contain a lot of metal. Very rare types.

LUNAR
Basalts and Breccias: Similar to samples brought back by Apollo missions.

MARTIANS:

3 different types: shergottites, Nakhlites, and Chassignites.

CARBONACEOUS
CHONDRITES


Very primitive, still very similar in composition to the pre-solar nebula.

Contain carbon and, occasionally, organic material.
Several groups, named after the type meteorite: O (Ornans), V (Vigarano), M (Mighei), I
(Ivuna), K (Karoonda), R (Renazzo), B (Bencubbin).

ORDINARY
CHONDRITES:


The most common type of meteorites. Divided in 3 types
:

H: High iron content,   L: Low iron content,   LL: Very low iron content.
The homogeneity of the crystallization is indicated by the petrologic grade, from type 3
(clear isolated chondrules) to type 6 (barely distinguishable chondrules).
