In the meteorite JaH 073 there are very small spheres. My guess is they
are micro concretions perhaps indicating a water action at some point in
this find. Too small for direct observation. At a magnification of about
350X they show up nicely.
They have been dismissed as chondrules, but I would say with as much
certainty as is reasonable in such cases, they are not.
Some are in my micrograph gallery
(http://www.meteorite.com/meteorite-gallery/meteorites-alpha_frame.htm ) under JaH 073 but if you like this sort of
thing, just ask and I will send you more spherule shots.
