I agree, ever since Dr. Agee started talking about how interesting this rock was I too wanted a sample. However I think that it is best left to the scientists to study.

NWA 7034 like Allan Hills 84001 is a Martian meteorite that is not a SNC. Hence the strange classification. At least it was not classified as a diogenite the way Allan Hills 84001 originally was.

Dr. Agee said on Facebook today that it was originally classified as an "achondrite-ungrouped" so it would be approved by NonCom in time for an upcoming conference (LPSC 2012). Without approval, the meteorite could not be accepted into a peer-reviewed journal. NonCom can be notoriously slow or reluctant to approve new types or classes of meteorite (Entmoot). If Dr. Agee had submitted it as a new basaltic-breccia Martian achondrite, it might have delayed the approval and he would have missed a chance to publish the meteorite prior to the conference. This happens from time to time with unusual meteorites. The "ungrouped" classes of meteorites are catch-all categories for meteorites that require further study or are anomalous in some way.

Now Dr. Agee is going back and resubmitting this meteorite for approval as a new Martian type (which it is). It remains to be seen whether NonCom will approve it as such, but they probably will.

Sutter's Mill is another recent example. It was rushed through the classification and approval process so it could studied and published in an expedited manner - because of it's potential scientific importance. The current official classification of "C - carbonaceous chondrite" is a similar catch-all type and it is likely that Sutter's Mill will eventually be reclassified as a CM breccia, CM2.1, or CM2.2.

This is a fascinating new meteorite. The Met Bulletin says it is a single stone with a single owner. So, one person controls the entire world supply of this meteorite. For collectors, everything will depend on what this one person decides to do with it. UNM has the classification sample, but don't expect to see any of that on the collector market.

Just heard on FB that there are four other smaller paired stones/fragments of this same meteorite that are known to exist and are not accounted for in the published TKW. Two of those fragments are in the UNM collection along with the classification sample. The other two are "in France". Those two specimens "in France" might end up being the only hope for private collectors.

Wow, NonCom moved pretty quick on this one. It was just approved last night : http://www.lpi.usra.....php?code=54831

Needless to say - I want, I want, I want. Gimme, gimme, gimme. ;)

The first time I saw the photo of NWA 7034 I commented that it almost looked like a lunar - I looked at these photos in the news pieces and on the MetBull and it still has a lunar-like appearance to me.

I'm pretty good about spotting a martian stone these days - I'm not sure if I could have gotten this one correct.

Maybe that is one reason they were not sure quite what they had when they first started studying this stone...
