Re: [meteorite-list] NWA 6694 / Abee
Hi Larry and Frank, yep in the future I will be better versed at creating photobucket files with specific pictures. Thos are pictures of our slice of Abee and the shadows are from the fir trees overhead. We had so few sunny days this summer that most folks here in the Northwest agree that Summer never happened here. The shadows from the fir branches on the Abee slice are almost as rare as the meteorite specimen, really! That shadow on the two edges of the slices of eucrite run through all of the slices and it looks very much like the heat rim seen on meteorites like you see on the Bagdad iron. But I think that it is a weathering affect from desert heating maybe. We are donating a slice to CML and to UCLA and they can tear them apart to try to figure out all the cool stuff that is going on inside this amazing rock. I have got to get a microscope with a good camera head on it. This breccia is really something that begs to be shared with everyone! Thanks to everyone who came up with suggestions for similarities. I really liked the comparison with Dag 400, don't I wish!

[meteorite-list] NWA 6694 (was: ad- offering for sale a killer eucrite breccia like none other!)
Hi Edwin! Great new addition to the world --- and I'm with you in mind and body on the medical issues, can't say enough ... Godspeed and all our prayers and positive thoughts be with you! On the Eucrite, Wow, it is so highly polished it sort of loses me to compare to my other stone age polished specimens: Nuevo Laredo? Igdi? NWA 3368? My cute little Stannern slice isn't so nicely polished, but might even fit the bill! Do you see something different in the matrix? I plead ignorance on how breccias could be evaluated, but speaking a little about my intrinsic fancies yours would be a great candidate to do a size distribution of included chunks compared to others and something would be learned from that, though I'm not sure what it would be, it would probably be very enlightening!

Greetings list Members! Writing to introduce what I believe to be one of the wildest and most beautiful eucrites ever to fall to Earth. The pictures attached are of a center slice from this single beautiful mass. The slice weighs 121 grams. Slices from this stone range from 50 grams to 145 grams. We’ve also had three thick slices cut for museum curation. Last month Marlin Cilz and his lovely wife Debbie came to Lake Oswego for a visit during their vacation travels throughout the Northwest. While they were here visiting we opened up the vault and went through a number of stones and irons that show cutting potential. Among other items Marlin talked me into slicing and polishing a large piece of our “Super Green” NWA 6693 the pyroxenite. In Tucson this year I bought a large oriented achondrite. It was a huge gamble and a high priced purchase. But it was one of those times when instincts told me that it was something special. I really should not have made the investment but the stone was so beautiful that I figured that if it turned out to be an HED instead of planetary that I could at least maybe get the investment back by selling the oriented stone whole. We donated a large fragment taken from an already broken surface (78 grams) to UCLA for classification. The stone was classified as a eucrite (NWA 6694). This seemed to feel like a bit of a letdown. Now the vault was home to a very pretty, oriented, expensive, loaf of bread. Well, Marlin looked at this not so little gem and said; “why don’t you let me take a single cut off this side of the stone where it is already broken and it will clean up the stone, give you a good look at the inside and you can still sell the whole thing if that’s what you decide you want to do. A week later we were talking on the phone and while talking about other pieces Marlin was cutting for me I said “hey Marlin, how about just cutting the end off of that stone and then send me a picture of the cut face. He did that and when he emailed the picture it was one of those moments that one remembers forever, a definite Kodak moment. My favorite meteorite feature has always been breccia. I remember getting week in the knees the first time I saw Chico at UNM and the first time I saw Abee. I could not be happier to get to share this gorgeous meteorite with all of you. We are selling it and there are roughly twenty slices. So please feel free to contact me or Patrick off list for sizes and prices and pictures. Just minutes ago I got the long awaited phone call from my neurosurgeon’s office telling me that my back surgery is scheduled for next Tuesday September 20th. So this rock truly is a gift from Heaven. Hopefully it will help pay the medical bills. I also want to take this opportunity to publicly thank Darryl Pitt for all of his support and knowledge regarding this pending surgery and everything leading up to this time. I never dreamed that someone could talk me through the pain like Darryl has done. Instead of feeling like I am falling apart, Darryl has helped me to feel like this is just part of the program. Darryl has given me more answers and information than any ten doctors could have. He has been through exactly the same problem and repair. May the Heavens bless Darryl by dropping loads of gorgeous meteorites nearby. Not on him but nearby! Thanks man. Sincerest regards, Edwin etmeteori...@hotmail.com to reach me or for Patrick at; patr...@etmeteorites.com http://s1110.photobucket.com/albums/h443/etmeteorites/ The slice featured in photos here measures 3mm x 11cm x 15cm and weighs 121 grams P.S.

I have looked everywhere I can think of looking and I have not been able to find any other eucrites that have a similar breccia. This list is a powerful resource of
Re: [meteorite-list] NWA 6694
Congrats on that nice looking breccia! Breccias are my favorites, esp. polymicts. It's like having different stones within a stone. Reminds me alot of DaG 400, except more clast laden. One of the few neat interesting examples of how eucrites can look so lunar. e.g. (NWA 6072 -- NWA 482) (NWA 5234 -- NWA 5000) and now: (NWA 6694 -- DaG 400) any others?

Hello List, Several list members brought it to my attention that the last 3 images in Edwin's photo album are of Abee, not NWA 6694. My mistake. I should've figured it out when I noticed the 'weathering' effect was not evident in the first images of the hand specimen, '6694, only the last 3 images of the big slab of Abee. I didn't see any comments on this weathering effect seen in clasts of the Abee, can anyone explain what's going on there? Having not ever seen a piece of it in person it's hard to tell exactly what I'm looking at. Now that I know it's an EH chondrite I'm wondering if the high metal is somehow causing the effect. Thanks!
