Re: [meteorite-list] Macrochondrules, My biggest Chondrule
Hello Mark, Christian, and List, Real whoppers, ... your macro- or megachondrules! Another interesting chondrule is present on NWA 081. The pyroxene seems to flower out from where the chondrule is. http://www.meteoritearticles.com/colnwa081.html That's a very interesting example. This may be a xenolithic clast and the flowering effect my have been caused by the impact of unrelated material into or onto the host meteorite. Reminds me of the lunar Mare Orientale impact basin with its multiple concentric rings. Very beautiful!

Martin, You may have stumbled upon an opportunity for the bead industry with your shameless ads...when a nanodiamond- or pearl-necklace won't do... Let's see... Since you have that very nice 276g Saratov 1918 witnessed fall slice at $1.70 per gram it might be profitable, especially if someone else is interested in the rest of the grains and micromineral fragments!, A one centimeter in diameter spherical chondrule must weigh very close to 1.67 grams (geek comment: density drops as size increases - a suspicion that the big chondrules are created by a different mechanism than the little ones). I'll give you $3 a gram (Almost double asking price) for some freshly shucked pearly chondrules of diameter 1.00 cm +/- 0.06 cm. For 40 of those chondrules, that would come to 40X1.67X$3= just about US $200. Not shabby at all for such as treasure.Hopefully shucking for chondritic pearls won't becoming viewed as cherry-picking the chondritic cocktail (Saratov Cocktail?).

Re: [meteorite-list] Macrochondrules/Saratov
Oddly enough I recently did this with a friable NWA. Approximately 100 grams was pulverized, separated, softened with 99% IPA, dried, and combed over painstakingly with a small paintbrush. Small chunks of matrix are hard to tell apart from the chondrules given the business of all the debris..eyes tend to go blind after a short time. Each chondrule was isolated then further cleaned of matrix, in all about eight hours work getting these puppies cleaned. http://www.nakhladogmeteorites.com/catalog/chondrules.htm Rob Wesel http://www.nakhladogmeteorites.com -- We are the music makers... and we are the dreamers of the dreams.

Re: [meteorite-list] Macrochondrules/Saratov
Acquittal - Judge Doug! The Saratov was sold long time ago and I don't have any other forsale. My homepage is many years old, I never found time to renew it (and had not the feeling to do so, as most of my pieces I distribute directely to the collectors from whose I know, that they might interested in).

Re: [meteorite-list] Macrochondrules/Saratov
With Bjurbole it works best like this: Put a fragment in a plastic display box, fix and pack it the best you can. Wrap it into paper, put it in a padded envelope and send it around with german post. The addressee will recieve a heap of dust with the isolated chondrules swimming on top. But the chondrules in Bjurbole aren't very large. I didn't try it with Saratov yet, but I guess, the larger the specimen, the farer you should send it. Buckleboo!
