Bombers did do night runs and some got lost out over the desert. You are right, no danger where this meteorite was recovered. I did not read all the posts after when I made the initial post regarding this. Just the appearance of the "fresh" crater and ataxite "shrapnel"... And knowing that WWII was fought in North Africa came to my mind. I have seen the photos. Pretty nice meteorite find. No doubt. Was there a meteorite, an achondrite, found in 1942 by a soldier during one of those North African Battles? I can't remember which meteorite it was, or the battle.

I agree ideally publication first would be very desirable but you above all should have experience with the the difficulties and understand that once the cat is out of the bag, it won't be put back in. These beautiful cats are like that. Study was done on a slice early this year on when the interesting meteoritical features were first observed by a leading classification scientist. You would have liked to see a 6 kg specimen which is already in its new home - beautiful meteoritical inclusions peeking out. As for the comments on bombs and mines, all of that is quite far from target. The WWII mining activity in Northern Africa was concentrated in a strip 30 km wide along the Mediterranean. No activity was south of Siwa (and very minimal there) according to the magical Internetwhich is as far as 250 km south of the Mediterranean. Only places along the Red Sea , Sinai and Suez were also mined. This locations is in the most distant part of the country you can get from the Sea. Like worrying about being careful walking around Madrid from the mining of Normandy. I don't believe any bomber would make the 2500 km round trip to the crater since that is further than the best vintage German bombers' range under optimal conditions and fueling, at a time of severe fuel rationing on a flight to nowhere. Finally, the surface texture of the meteorite is not of an age anywhere near Sikhote Alin (basically WWII age), it is older. I am no expert in caliche formation, but there is a thin layer where in contact with the ground. ...and it only rains about once every ten years there for the last 7000 years. It looks to me of neolithic age but that is unfounded conjecture. Perhaps a good movie could be made about a DeLorean fitted with a flux capacitor delivering ataxite forged heavy ordnance to warring cave painters ... this was the humorous image that formed in my mind as I read your comment. I hope you'll get to look at the material at some point to get a better idea to base your next comments and I think you will quickly have a change of heart. Some nice photos have been posted already, including this one: http://www.diogenite.com/ataxite/255c.jpg Kindest wishes and thanks Doug -----Original Message----- From: Steve Schoner <schoner at mybluelight.com> To: meteorite-list at meteoritecentral.com Sent: Wed, Jun 23, 2010 10:12 am Subject: Re: [meteorite-list] New Iron (Ataxite) SHRAPNEL That would be a great find as a new ataxite (low nickel) with an impact crater. But until the analysis is in I have my doubts as the shrapnel part has me wondering... This area of the desert was most probably flown over by bombers back in WWII. Could that hole be the product of a bomb that was dropped? Bombers often unloaded hung up bombs in odd locations. At any rate if I were searching any area close to a WWII battlefield it would be wise to keep that in mind, as any unexploded ammo or even mines might still be active. Would not want any to be the last casualty of WWII.

Thus, any Aeolian deflation or wind shaped sedimentation pattern around the crater would have to be oriented along this axis. This appears not to be case. Instead we see a radial pattern with the crater as its center." Svend has described poetry in motion; I am going to save his description for reruns with a cup of coffee and savour the detailed analysis, perhaps when life is at a kind moment and I am out in the desert observing the night sky and inventing my own constellations for family members. The impact rays are probably already covered quite well, but if it is not clear, let me try to add this: We have a central source of material and under Richard's hypothesis, wind blowing down points on the rim to form these "rays". We look at the rays and the first thing we notice is that they are as quite well defined. Svend's comments about the character of the prevailing wind direction, pavement and bedrock aside, let's try the strategy of proof by contradiction strictly under Richard's hypothesis: Suppose this is a sandy or powdery place where the wind can blow out spokes from the sand source(hole, crater, pit, whatever). Looking at the rays from all directions we are forced to reason that the wind must be blowing from all those directions or else we wouldn't have a hub and spoke design around the crater. But ... if the wind is blowing sand and powder spokes from all directions, why would the spokes be linear, nearly as well formed distally as near the crater? Because wind from all the directions of the compass would cause a scattering proportional to the distance from the crater, perhaps curves if it was a windstorm from another direction, and not a sharp delineation towards the ends of the rays like a bicycle wheel. The absence of this is a contradiction ... the backbones of the rays are too straight and well defined to support Richard's idea. A much simpler explanation is that someone painted them on a something solid ground - who better than Mother nature responding to the impact? Kindest wishes Svend, and Richard, thanks Doug ____________________________________________________________ Refinance Now 4.0% FIXED! $160,000 Mortgage for $633/mo. Free. No Obligation.
