Interesting photo's. Are those vesicles which are visible especially in
the larger slices?

Made me wonder what the composition of gases trapped inside them would
be? I assume that somebody, somewhere has looked into this? Surely this
would provide excellent evidence for their source, as it did for Martian
stones. If Muong Nong formed in 'molten pools' on the Earth surface then
presumably the gas mix would be that of Earth hundreds of thousands of
years ago. Would the same be true for the other shapes if their source
was the Earth or Moon, or would the passage through Earth's atmosphere
from either source result in the same composition?

Certainly provided me with some food for thought, I'd be interested in
hearing from other, better informed, list members!

Thanks,

Matt.
