G'day Graham,

I believe a lot of work has been done of vugs/vesicles over the years. There
is a well known paper by Edward Olsen called "Vugs in Ordinary Chondrites".
It's pretty old now but it does still seem to get referenced in modern
papers.

If you have never used NASA Ads then I highly recommend it! It's where I
find 90% of my material when researching meteorites and in my personal
opinion is one of the very best scientific resources available. Here is the
link:

I also make mention of the vesicles in Ibitira which is an anomalous
basaltic achondrite:

Hope that helps,

Jeff
