This issue is not unique to NWA meteorites. The same thing could be said for
Antarctic or other desert finds. Yes, Antarctica is a desert. The same issue
applies to falls. How much Allende is really out there? Nobody knows for sure,
the same can be said for Murchison. You can make the same claim for just about
any fall.

Adam the difference between NWAs and all the other falls is that NWA nobody knows where the strewn fields are. As for the rest, there is data on strewn fields and correct documentation that is used to asses the fall or find.
?
But with a NWA I find that people say that only buy my NWA because its the real deal and the pairs are inferior. The problem with that is with NWAs are collected and through out the months or year the same meteorite gets recycled back to dealers and in a since every NWA stone has to be classified cause of the collection process.
?
Good example is NWA 2999, I think this meteorite has 2 other pairings if not more and think how many pairs it will have in a few years from now? And another good example is NWA 5400 which could have a few pairs, which are very likely.
?
Now when people bank of there NWA as being rare cause of low TKW it seems that it this could be misleading cause of the circumstances that NWAs present to science and they way they are collected.

lets say you found an NWA and its about 1000g and you get it tested and its a
new NWN. Now you can say its rare because there is only 1000g, but do you
really know that for sure? From what I have seen, its not the case, and NWAs
keep getting paired with each other more time then not.... I think that's why I
tend to stay away from NWA's for that reason and others.

the same can be said for Murchison. You can make the same claim for just about

among them. I have lost more value by collecting new falls than I have
collecting finds. This is why I tend to stay away from new falls. The price
drops off sharply within a few months once the initial excitement disappears.


I lost a small fortune on New Orleans and Claxton by letting the market
determine the value by putting them up for auction with no reserves.

Happy Hunting, Long live the finds because without them we would have no lunar
meteorites,

Hello Greg S and Listers,
?
Now the slight problem I have with NWA's is that you really don't know how much of that?stuff is out there. That can work in your favor and against you. So lets say you found an NWA and its about 1000g and?you get it tested and its a new NWN. Now you can say?its rare because?there is only 1000g, but do you really know that for sure? From what I have seen, its not?the case, and?NWAs keep getting paired with each other more time then not.... I think that's why I tend to stay away from NWA's for that reason and others. Plus it seems that every meteorite is unique in its own right and some bank off that uniqueness and rarity to pump up the price in the NWA market. But once more is found, that type isn't that rare anymore, so that's why I stick with the historic falls, cause that event can only happen once and there is a rich history and legacy to back up that meteorite.
?
Also?the NWA?5400 is speculated to have a connection with Earth. Now?in my own opinion if this was the find of the century, wouldn't you think there would be more research papers written about this monumental find that some people praise it to be? All?I can find are 2?papers and the second paper?doesn't?even seem that promising. Good example is Almahata Sitta. That meteorite has been around since NWA 5400 and there is so much information and papers upon papers?about this meteorite, and?the research hasn't stop, but for the NWA 5400, its?is a trickle, 2 papers whats up with that? Again, the evidence isnt there and a swashy?thought out theory, which other theories have been brough up about the NWA 5400 and where it came from, more evidence please.?
?
But at the end of the day people have their reasons why they collect and some are drawn to classifications and others to historic falls. The good thing for any collector is to do research and learn what they are?going to buy before?they buy it. Also?they learn alot more about meteorites in the process and gain a since of understanding of where meteorites came to be.
?
If any one has the?time, check out this link below, its a great paper written?by Ursula B. Marvin, explaining the?beginning of meteorites from a historical and scientific perspective.

Wow - this is making my head spin.? It is my understanding that the O isotope data is necessary to show the relationship to the early earth-type rocks; it has to fall on the TFL.? I would think this is necessary to prove a "pairing" to NWA 5400.? Until then, it is not 100% certain.? The fact that NWA 6292 IS paired to 5400 suggests that there could be more of this unique meteorite out there.

Just my thoughts,

Greg S.
