It looks to me like the holes are just where chondrules have fallen out of
the matrix. From what I understand, vesicles form by gas being "boiled out"
of liquid rock. That's why they've only been found in a eucrite, because
it's an igneous rock. It's wierd that that is the only one that looks like
that though. Perhaps a loose matrix or something?
