Classificational tidbits culled from:

HUTCHISON R. (2004) Meteorites: A Petrologic, Chemical, and
Isotopic Synthesis (Cambridge Planetary Science Series, pp. 506):

Page 49: " ... St. Mesmin is LL3-7, H6 (Dodd 1974). Occasional
complexity, we believe, is the acceptable price of accuracy."

also on page 49: " ... St. Mesmin contains contains type 3 material
in addition to the dominant LL6 lithology. Some slices additionally
show a shocked dark fragment of H6 lithology that signals mixing
between parent bodies."

and on pages 51-52: "It is proposed that the maximum amount of
information should be incorporated into the classificatory shorthand
for breccias - St. Mesmin for example, would be classed as LL3-7, H6.

Any comments ? Jeff (Grossman) ?

Best wishes,

Bernd
