NWA869 is one of the most common meteorites from Africa. Luckly for us, i= t is also one of the nicest. Me and Dean Bessey have recovered a good sha= re of it and sold it under this name. Other dealers have submitted sample= s under different numbers. Farmer and the Hupes use NWA787. Matteo origin= ally got the number NWA900 for the stone, as seen in Richard Norton's boo= k "The Cambridge Encyclopia of Meteorites, page 144. Matteo has since got= ten several other numbers for the stone was well. Rubin classified NWA869= as an L4, but then reclassified it as an L5. It should appear in the Met= eoritical Bulliten as an L5. Farmer-Hupes got NWA787 classified as an L6.= Matteo got an L3.9-6 classification. Two times with a brecciated classif= ication, and two times without. =20 When I was in Tucson, several of the moroccan dealers had large amounts o= f this stone as well. I tried telling a few of them the classification an= d wrote it down for them but then I would see someone looking at one ten = minutes after I talked with the Moroccan sellers and they would "forget" = my conversation. None of the moroccan dealers seemed to care about the cl= assification. =20 So what is the Classification? Rubin says its an L5, I am willing to go w= ith that. Is it brecciated? I think it is. But hey, if Gold Basin isn't b= recciated, then I guess I am willing to say NWA869 is not either. Breccia= tion has more to do with how it looks in a thin section rather then the e= ye, so this can be confusing at times. =20 Some have reported Carbonaceous enclosures in NWA869. What I believe they= are seeing is shock evidence in the stone. The more shocked parts of the= stone is usually darker and this is where I have seen dark inclusions, t= hat I think others have labeled Carbonaceous in error. =20 There is a lighter golden version of NWA869 as well. While I have not see= n this part in a thin section, I believe this to be a more weathered part= . Or it appears such is more accurate. Now, I have also seen the golden v= ersion, in the middle of the stone before and not on the edges, but it do= es look a lot like typical weathering I have seen in the African stones. = I think I if I remember right, NWA869 got a weathering of 2 (?). =20 Me and Dean have sold at least 600 kilos, mostly Dean. With what I have s= een at other dealers, the moroccan sellers in Tuscon and what I have been= offered from Morocco. I would say there has to be more then 1000 kilos o= f this stone out there. Maybe 1500 kilos or more. Now, arent we glad it d= oesnt look like Dhofar 020....:-) =20 If I can find the time soon, I will post pichures of thin sections from N= WA869. =20 Mark Bostick PS: I few 12+ pound NWA869 and would be willing to trade one if anyone is= interested? ----- Original Message ----- From: Jamie Stephens Sent: Tuesday, December 10, 2002 9:54 AM To: Meteorite-List Subject: [meteorite-list] The biography of NWA869? List Members, I suspect that NWA869 has an interesting history. It's not =20 a story like http://www.meteor.co.nz/aug96_1.html or similar classics. Instead maybe NWA869 is a good archetype for a modern (?) meteorite story. Nomads (who?) find some about here. They take it to somebody =20 else, who talks to Dean (?) at midnight in the desert (or in =20 his car at a drive-thru via cell phone). Dean negotiates. =20 Meanwhile, other nomads find more material possibly paired =20 with NWA869 ... Dean brings back some, which he sells to =20 resellers and collectors. A notorious reseller engages in odd busines practices. Some controversy brews somewhere. =20 NWA869 is classified. Prices fluctuate. Etc. Please note that I have no idea. I'm just making that summary narrative up. I can see a blockbuster movie starring Harrison Ford as Dean (and maybe a montage of others). Dean and others, could you help flesh out this story? I'd be happy to summarize (if needed). List Members, if you're not interested, let me know. I'll repost and ask for info off-list.
