My reference was:
G.W. Kallemeyn and A.E. Rubin (1995) Coolidge and Loongana 001
A new carbonaceous grouplet (Meteoritics 30-1, 1995, p. 20):
"They are also similar in petrologic type (3.8-4) and shock stage (S2)"
In Monica Grady's Fifth Edition of the Meteorite Catalogue, we find:
C3.8 (not CR !) - ungrouped
For Alex Seidel it is still a "C4-UNGR" (pers. comm.).
In an article by Huss et al. (2001) it is a: CV4
HUSS G.R. et al. (2001) Aluminum-26 in calcium-aluminum-rich
inclusions and chondrules from unequilibrated ordinary chondrites
(MAPS 36-7, 2001 pp. 975-997).
Does anyone (and by anyone I do not mean Bernd :-) know
the correct classification of Coolidge carbonaceous chondrite?
(CB) - No, not Bencubbinite
