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
