Hello George:
I noticed the armored chondrules on my Clovis H3 as well (which is off
the piece yours came from).  I also have a slice of El Djouf 001 (CR2)
which exhibits the same characteristic rimming. So yes, I believe your
interpretation is correct. Armored chondrules are not rare by any means,
they are just neat to look at under the scope! Look at pieces like
Bluff(b), Felt(b), and Densmore, you will see the same thing.

Best Wishes,
