Hi Rob and List,

First of all, sincere congrats on such an "exotic" classification. I am eagerly waiting
for Jeff Grossman's comments! Well, slashes (e.g. L4/5) indicate transitional classes
whereas hyphens (e.g. L5-6) indicate breccias. In other words, an LL6-L4 chondrite
seems to have an LL6 lithology and, well,...now it's really getting difficult especially
because the Met.Bull. entry doesn't give any details,...is the L4 lithology incorporated (embedded) into an LL6 matrix (?), is there a clear-cut boundary between an LL6
lithology and an L4 lithology (something like this: left part of the stone LL6, right part
L4) or are there L4 islands floating in an LL6 "sea" or, maybe vica versa?

Curious minds just wanna know ;-)

Best wishes,

Bernd
