Date: Thu Apr 22 10:31:14 2004 Message-ID: <20040416132448.D05525365A_at_pairlist.net> I am wondering if Oum Dreyga (Amgala) will be accepted by the Nomcom as = a witnessed fall. As long as it is not confirmed to be a fall, it is still nothing other = thing than a find. My personal opinion is, that it will be not accepted for 100%. Just see the latest MetBull 88 what happened to Bensour. It is listed as "found, possible fall" Long faces in the collectors community - it was stated as a fall since = it appeared on the market. And now ??? What is it - a hybrid ? Paid for a fall, got a "found, = possible fall". And this took 2 years to find out. I think it is a solomonic decision of = the Nomcom. And this is not the only one :=20 It was the same with NWA 820 (Hassi Labyade). The Nomcom did not accept = it as a fall. Let's wait and see how much kgs really appear and if it will be a fall = or not.

However: =A0 1) I know of at least one other 1kg+ 'Amgala'=A0being offered in Morocco = at the moment. Whatever it is, it's actually a=A0very nice (& even more expensive) specimen. =A0 2) I don't think there will a huge drop in Amgala prices because there doesn't seem to be enough weight. Certainly not as much as Bensour and = Park Forest. =A0 3) Side by side, Zag and Amgala are quite different. I could be wrong = here but even the crust on Amgala seems a little more..... 'velvet-like' than Zag. =A0 Anyway, it's a very nice meteorite whatever it is! ;-) =A0 Cheers, =A0 Jeff Kuyken I.M.C.A. #3085 www.meteorites.com.au =A0 ----- Original Message -----=20 From: j.divelbiss_at_att.net=20 To: thomasmeteorites_at_wanadoo.fr=20 Cc: philippe thomas ; meteorite-list_at_meteoritecentral.com ; Adam Hupe=20 Sent: Friday, April 16, 2004 9:40 PM Subject: Re: [meteorite-list] Main mass of Oum Dreyga (Amgala) recovered = ! Hello All, Last month I reported on my first take of the Amgala individual I got = from the Hupe's that when cut sure looked like Zag to me. It being a small individual of about 20 g, it is not easy to see a lot of detail in a end = cut of 2g...so I'm still not sure what I have. The piece of Amgala I cut has a very nice blackened crust, and inside it = had both the blue-ish black lithology and the lighter brown H6-like material I've seen on Zag. I do have some very nice crusted individuals of Zag = whose crust looked just as nice as the piece I received. Since then I've = bought and seen slices of Amgala that do look different than the first piece I cut...the interior of the Amgala slice I got looked more "yellowish" = inside as if they are slightly oxidized. No significant breccia in my slice. whereas the piece I cut myself did have some. Did I buy a Zag that was freshly picked years ago and sold to the Hupe's = as Amgala...maybe??? I'll be home later tonight(12 plus hours from now) if anyone wants to see a picture of my Amagala(Zag?) individual.=20 What I would like to see sent to the list today is someone's picture of = a fresh interior of Amgala that is not yellowed...if there is such a = thing.=A0=20 Curious now, John =A0 > Dear Adam and List Members, >=20 > I can quite believe that the main mass of this meteorite is weighing = over 2.5 kg=20 > (If it=92s the=20 > case, I ask to everybody to excuse me for the title of my first = message) but I=20 > have never=20 > heard about this piece and nobody has shown a picture of it. >=20 > I know, of course, that this meteorite (Oum Dreyga/Amgala) is already being=20 > studied at NAU,=20 > but as it often arrives, this meteorite will be analysed by several=20 > laboratories.
