Absolutely right, ... stunning, fantastic, breathtaking picture! Surely, a
dramatic moment unfolding before one's eyes: A porphyritic chondrule
fragment caught in the act of colliding and demolishing an "innocent"
barred olivine chondrule.

A.L. Graham wrote in an article about the Julesburg chondrite that
"numerous chondrules indent each other" and that "some chondrules
have been welded to adjacent silicates".

The right part of the BO chondrule looks as if it is being welded into
the adjacent, shock-darkened pyroxene laths

Best wishes from the proud owner of 43.5-gram Julesburg slice (purchased from
Walter Zeitschel) and a Julesburg thin section (acquired from Mark Bostick),
