Hello List,
I just ran into something new I don't recall seeing
discussed here. While examining a piece of Mesosiderite NWA 1817 (which I
believe might be paired with NWA 1878), I found a small cavity in an inclusion
with tiny gas bubbles. The inclusion has a fairly dark matrix, but the
little cavity is filled with a very clear, glass like material and several
bubbles are clearly visible.
Here is a link to some photos ranging from 0 to
100x. http://f2.pg.photos.yahoo.com/ph/skyrok99/album?.dir=/bd7d I
took them through the eyepiece of the scope so they're not the best,
but you can see the bubbles at the higher powers.
Is this common and I am just running into it for
the first time? Any background on this clear material and how/why the gas
was captured there? Maybe an impact with a beanaroid sometime in its past
;-)
Thanks for any feedback.
