Hello Elton and all,

I believe the "decimal" value in type 3 chondrites is commonly being applied
to carbonaceous chondrites. In the new "purple" catelogue both CO3 and CV3
chondrites are being classified with decimals.
For instance Colony is classified as a CO3.0, Kainsaz is a CO3.1, Ornans is
a CO3.3. In CV chondrites, Allende is a CV3.2, Vigarano is a CV3.3, and
Axtell is a CV3.0.

Several others are classified as only a CV3 or CO3; I assume in the future
they too will have their "decimal" or perhaps they may be too weathered?
