[meteorite-list] Vesicle gases

[Dave Harris]

Hullo

On a more serious note, and I think I have asked this question before but I
do not recall any answers - I was looking at my Mt. Taz again and checking
out the vacuoles that spongify (!) the rock - so what gases were inside the
rock to create the pores (like Ibitira).

I can understand gases from planetary sources (same mechanism as pumice
creation on Earth) but can't be certain that these gases in Taz, or Ibitira
would be the same.
Does freshly cut Taz have a distinctive odour?


Any ideas? Any research papers?

Yours, in search of knowledge,
