Hi Anne, Dave and List,
I believe those clasts are orthopyroxene not olivine judging by the
cleavage but you would need a Microprobe to be sure.
All the best,

So I would like to assume that a mesosiderite is not a
core-mantle sample
(like a Pallasite) but the smushed up surface of a
well pounded asteroid.
I have a couple of those too. They are beautiful.
Just go look:
That mesosiderite wants to grow up to be a
