Just like Adam, I've been desperately looking for triple junctions, ... none :-(
Unless it is something "anomalous" my recent guess (olivine diogenite) is
wrong because diogenites do have triple junctions!

I've been looking for chondrules or fragments of chondrules, ... none :-(
Metal-rich + absence of chondrules, does that look like a CH or a CB?

I would expect to find chondrules in a CH chondrite and I would expect
to find larger pyroxenes in a CB chondrite (just think of Gujba, for example!)

*If* the interference colors are correct, this thin section is excessively rich in
brownish pyroxene, and, another *if* it is orthopyroxene, we might be looking
at a metal-rich (anomalous) aubrite.

Oh, well, ...
