The intrepid type collector, forever at the mercy of nomenclature.
What was once CV4 is now CK4. Over time, the type collection
continues to grow and grow.

According to David Weir's Meteorite Studies website, here is a
condensed breakdown of the known types -

CM2 (subdivided into CM2.0 to CM2.6)
CM3
CO3 (Ornans) (subdivided into CO3.03 to CO3.7)
CV (Vigarano) (also CV2 and CV3)
CK (Karoonda) (CK4, CK5, CK6)
CR (Renazzo) (CR1, CR2, CR3)
CB (Bencubbin)
CH
CR ungrouped
C4 ungrouped
C ungrouped (Tagish Lake, others)


Ordinary Chondrites :

H impact melt
ungrouped ordinary chondrites


Enstatite Chondrites :

EL (EL3 to EL7)
EL impact melt
EH/L
EH (EH3 to EH7)
EH impact melt
ungrouped enstatite chondrites

K (Kakangari)

ungrouped primitive chondrites


Achondrites :

Howardite (subdivided into fragmental breccia and regolith breccia)
Eucrite (monomict and polymict with each having subclasses)
Diogenite (monomict and polymict)
Olivine Diogenite
Dunite
Ureilite (monomict and polymict)


Martian achondrites :

Shergottite
Pyroxene-phyric basaltic shergottite
Olivine-phyric basaltic shergottite
