[meteorite-list] Link to webpages about Nevada impact site
Hello List, Since I've just returned from an extended field trip, there wasn't proper time to compose a typical Bob's Findings article for Meteorite-Times.com this month. But I thought it would be nice to still give our readers the opportunity to view the most recent, preliminary results by a group of researchers known as the Stratofox organization, and of their fieldwork in the Black Rock Desert. So, instead of my usual article, I decided to make a webpage that would simply be a couple of links to the Stratofox group's website that describes their latest efforts at trying to locate evidence for a suspected impact crater in Northern Nevada. It's just that I would like to give the meteorite community some exposure and visibility to the work done by the principal investigator, Ian Kluft. In case you're interested, here is a link to get you started: http://meteorite-recovery.tripod.com/2008/sep08.htm Regards, Bob V . __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] meteorite sale - please read message
Dear meteorite friends! Once again I need to tell you about a tragedy here in Thailand and I hope that you can help us out. A short time ago, my long-time friend and companion of many Chiang Khan expeditions drowned in the Mekhong river. Mr Tim has left his wife and several children behind, who have now lost the primary breadwinner. Friends of Mr Tim's informed me about the financial crises that the family is in. Mr Tim was a loyal and honest travel companion on many of my expeditions, and we had become good friends. For this reason my wife and I have tried to help Mr Tim's wife and family and have financed a small grocery store. This should help support the family. The total sum we gave towards the store was around Thai Baht 470,000, or around Euro 9,500. We have scrounged up this sum ourselves, even our 4-year- old daughter had to plunder her bank account. To recoup this money, which we now miss dearly, I have decided to sell the last few larger specimens in my collection. Amongst these pieces are two larger Chian Kahn specimens (all the remaining pieces are under 5g). A museum specimen, very unusual, 27.5g. For this exceptional piece I am asking 90 Euro/g. The second item is a 100% crusted, beautifully oriented Chiang Kahn, 63.4g. Here I am asking for 45 Euro/g. Also Offered are the following pieces: * NWA4935, shergottite, 2.956g, partslice * D hofar 310, lunar, 0.352g * NWA4483, lunar, 5.612g, endcut Please see these specimens here: http://fotocenter.aol.de/galleries/zneutronz/ As I have mentioned, we hope to achieve Euro 9,500 with these sales. We trust that you will support us in light of the circumstances of this sale. Thank you so much for your time and consideration, Regards , Oliver IMCA#6131 Oliver Alge Calle Las Artes, Loc. 2 Res.

Re: [meteorite-list] Acfer breccia - provisional classification results
Hi List, In January 2007, I posted a link ( http://home.planet.nl/~rlenssen/Acfer500g.htm ), pointing to some pictures of an odd looking meteorite, asking for comments. This request resulted - via List member Frederic Beroud - in a contact with Jerome Gattacceca from CEREGE in France, who conducted magnetic susceptibility measurements, and kindly offered to help to have it classified. Today I received (provisional) classification results, and want to share them with you: Provisional results by: M. Denise (MNHN)/J. Gattacceca (CEREGE) breccia LL6-L4 shock stage S2-S4 (S2 for the LL lithology and S4 for the L lithology) W1 Microprobe analysis (LL-L lithology) Fayalite 31.5±0.6-25.5±0.5 Fs 26.5±0.4-22.2±0.3 So, it turned out to be an LL6-L4 breccia! I wonder how rare this kind of breccia is, and especially if such a breccia has special scientific value, above just a mix of LL6 and L4 material. Does anybody know an answer to this?

Re: [meteorite-list] Acfer breccia - provisional classificationresults
It is very unusual to have one ordinary chondrite group mixed with another. Dimmitt (H regolith breccia) has an LL5 clast; St. Mesmin (LL regolith breccia) has some H clasts. Let's get this thing named officially through the Nomenclature Committee.

[meteorite-list] Carolina Bays
Darren and list members, Thank you for the links to the Carolina bays article. I believe that the researchers are probably onto something that will likely be the cause for megafauna extinction. The sterile layer (devoid of cultural remains) above the Clovis layer that exsists in Texas Clovis sites such as the Gault site has always troubled me. This layer can be a few feet in depth and seems to indicate a rather long hiatus of human activity in places where the rest of the record is rich in cultural debutage. Recently I read somewhere of micro-craters on some megafauna horn sheaths and other bones in Alaska. All of this evidence seems to be pointing at a cosmic calamity being a likely death-knell for the big game hunted by early Americans and probably more than a few of the Clovis people themselves. While diesease and overhunting could push species to extinction they do not explain the break in the cultural record. I am a new 'list' member who specializes in tektites- Bediasites in particular. I have hunted them for almost two decades and have found between seven and eight hundred specimens and one Georgiaite. More on that later. Maybe Chicken Little was right...
