[meteorite-list] NWA 2921 Classification CORRECTION
Dear List Members, I just received an email from Dr. Bunch, there was an error in the lab. Here is part of his email: Dr. Bunch's reply: Yes there is a mistake. Your section number is RHH4 and was read as PHH4, the data of which is ET's CO3.5. Yours is an R3.8. complied the data before I left and I did not double check it. --- R3.8 S1W3Fa39.3 ± 1.2; FeO/MnO = 72-76 (we started to use this constraint which is foolproof in identifying some carbonaceous chondrites, don't need O2 data anymore). We have used our hundreds of analyses to provide the following FeO/MnO ranges: R = 68-90; CK, 100 - 130; CO, 110- 150; CV 140). Some overlap but other compositional characteristics overcome the minor overlap of CK and CO, which do not look the same anyhow. I don't know who said that it looked like (NWA)3146, many Rs do but they are not paired with (NWA)3146... Sorry about the mistake and thank you for pointing it out. Thank you Christian, Marcin and all who brought attention to this mistake. It just shows that when we work together, good things happen. I have corrected the current auctions on eBay to reflect the R3.8 classification and have notified the two members who purchased some using Buy it Now. Now, I wonder if crow tastes good with mustard...

I don't know who said that it looked like (NWA)3146, many Rs do but they are not paired with (NWA)3146... Sorry about the mistake and thank you for pointing it out. Its in our interest to help correct every error. There are alot of meteorites so its natural that there will be any of them. But I reflect about other thing. NWA 2921 is NOT paired with NWA 3146, 2289, ..., becouse NAU checked this for possible pairings or its not paired becouse they not checked it for pairings ? Becouse this can be interpreted in 2 different ways. Lets see my NWA2698 Howardite. Its material that is paired with many other NWAs, including the father NWA1929. But If I will send it to lets say, Russian Lab I will get unpaired meteorite becouse they dont have comparison material. Also NAU can't technicaly (I think) compare every Howardite to many many others for possible pairings. My specimen is paired, becouse I say to Ted, to compare it with NWA1929, becouse Im was sure that it was the same material. So unpaired meteorite can't alvays mean that it is unpaired, but only that it was not classified as paired. If Im wrong, correct me. -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryt.net [EMAIL PROTECTED] http://www.PolandMET.com [EMAIL PROTECTED] http://www.Gao-Guenie.com GSM +48(607)535 195 [ Member of Polish Meteoritical Society ] __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
