Writeup from AMN 33(1):
MET
01149 original classification in AMN
26, no. 2 (and Met Bull. 88) as a CK3 chondrite, but several unpublished
studies have yielded information inconsistent with this classification. Because of the small nature of the sample,
and the relatively rare class of CK3, the curator has decided to change this
classification even with unpublished data to avoid confusion from requestors. MET 01149 is re-classified as an R3 because
it contains many grains of Fa39 olivine, R-chondrite-size chondrules, and
several cryptocrystalline chondrules
(which are very rare in CK chondrites).
INAA data generated at UCLA indicates that the rock has low abundances
of refractory lithophile elements and relatively high Fe, consistent with an
R-chondrite classification. (A. E.
Rubin, 2009, pers. comm.).
