However: 1) I know of at least one other 1kg+ 'Amgala' being offered in Morocco = at the moment. Whatever it is, it's actually a very nice (& even more = expensive) specimen. 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. 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. Anyway, it's a very nice meteorite whatever it is! ;-) Cheers, Jeff Kuyken I.M.C.A. #3085 www.meteorites.com.au ----- 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. =20 Curious now, John =20 > 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.
