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:
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).
