The shape suggests a water worn pebble = more than an ablative process to me. If the refractive material were = meteorite metal you would get more of pull from a magnet judging from = the amount present. The things I look for are a valid fusion crust, = proper shape, nickel-iron metal, shock indications and how the stone = weathered. I see nothing that indicates a meteorite to me but I have = been surprised a few times in the past. Very interesting stone whatever = it turns out to be. All the best, Adam ----- Original Message -----=20 From: Bernhard "Rendelius" Rems=20 To: meteorite-list_at_meteoritecentral.com=20 Sent: Thursday, February 26, 2004 1:38 PM Subject: [meteorite-list] Help me solve a mystery - NWA mystery Hi, app. 2 weeks ago, Steve Arnold (Illinois) sold a "mystery NWA" on = ebay. This is the text that came with the auction (as often with Steve, = no pic): "Up here for auction is a mystery.This is a 134.9 gram whole stone = that has been cut by AL LANG.It is a unclassified NWA mystery stone.I = had bob haag,richard norton,al lang,ed thompson,blaine reed, and a few = others give thier opinion on what it might be.No one knows.It has a very = rich dark brown matrix.Very few or none at all with chondrules.High in = metal, but it pulls very weakly even with a strong magnet.You can be the = lucky winner of this mystery stone and you can try and get it = classified.It measures 6.5 cm x 5.2 cm x 3.8 cm.I will start the bidding = at $1.00. Good luck." Well, I bidded and won the item. Today it arrived. I had a closer look = at it, took some photographs and am looking for your expertise now. Let me describe the tactile impressions: The item is feels pretty cold = when you hold it, and it has about the right weight for a meteorite of = this size. However: the outside feels quite "soft", more like an = ordinary stone than a meteorite, like a pebble that has been in the = water. There is indeed a lot of metal visible from the outside, but on the = cut surface, the deeper you go inside, the less metal you find. A close = examination with a 10x magnification showed no chondrules at all, at = least for me.=20 Here are three photos of the object (they are quite large in order to = reveal more details). I have brightened the photos and added some = contrast and some mild sharpening, but I'd say they are true to the = visual appearance of the object: http://metcollector.rendelius.com/mystery1.jpg http://metcollector.rendelius.com/mystery2.jpg http://metcollector.rendelius.com/mystery3.jpg So - what's your impression? Is it a meteorite at all? What is it?
