Re: [meteorite-list] Tiny Bubbles in NWA 1817
Hello Bernd and List, Thank you very much for your very clear and logical explanation. Not sure why the problem with accessing the photos on yahoo, but here is a link to a different site that should work. http://my.execpc.com/~eagle1/ Thanks again for sharing your amazing knowledge of meteorites.

[meteorite-list] Tiny Bubbles
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=/bd7dI 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. Don Shervey
Re: [meteorite-list] Re: Beanies and Meteorites
Dear Geoff and List, That lucky fan you mentioned might have been me. I won a nice little Odessa half stone with beautiful inclusions and a model of Star Trek's Star Ship Enterprise from Steve. The Odessa is still one of my favorites, and the Enterprise has a permanent docking station next to my computer. It has flashing lights and a weapons array, so now when I loose an auction to a last second bidder, I can let loose a few photon torpedoes and a good phaser blast and feel a whole lot better. Live Long and Enjoy Meteorites...
