[meteorite-list] Meteorites, stock market, spending habits recessions
Hi List! I'll stay away from the politics because there is plenty of blame to go around for the bureaucrats and plutocrats. But I can say for myself, I have only owned one credit card in my entire life. It was several years ago and I ran up a debt on it. I then paid it off and cut it into micromount-sized pieces. I haven't owned another since then and I never will. I pay for everything with cash or my debit card - I don't finance anything. Has this hurt my credit rating over the years? Sure. But I can sum up my credit debt with one number - 0. That is a good feeling. Of course, the cash only lifestyle is not for everyone and I will qualify my success with this - my wife and I are only a few months away from realizing our dream of living full-time in an RV that runs on solar power and has a very small carbon footprint. (look out strewnfields, here we come!) If one follows a minimalist and non-materialist lifestyle, it's very easy to stay away from credit and crushing debt. Yes, it is possible to live comfortably without any credit cards or borrowing money - you just have to live within your means and don't try to keep up with the Joneses nextdoor who are in debt up to their eyeballs and when they die, their children will inherit a house with multiple liens against it. As for meteorites, buying them and selling them in a depression, I have had some interesting responses off-list to my intial post/question. Several dealers, large and small, emailed me off-list about their sales. I will not divulge names, but the response was mixed. The smaller dealers, like myself, have been hit the hardest. The larger and more diversified dealers are doing pretty well. (Lesson to self - diversify!) I do the bulk of my business via an email list I have compiled over the years from collecting and restoring antique telescopes. That list has about 40 names on it. Many of those customers would be considered very wealthy. One customer recently told me that he lost about $200,000 in one week on the stock market. Another saw his retirement fund shrivel by almost 50%. These people have stopped buying meteorites for the moment, although they still plan on collecting and buying in the future when their personal financial situation improves. This past sunday night, I did manage to make 2 sales - not long after I belly-ached to the group about my lack of sales. It's almost as if someone was listening and took pity on me. I made a $100 sale and a $50 sale. My profit on those 2 sales, after shipping, will be $115. That's a healthy margin, but that margin is not going to make me rich when my overall numbers for 2 weeks is only $150 in gross sales. The only thing I can do is to sit back, wait, and ride out this slow spell. This has put a freeze on acquisitions for my personal collection since I finance my personal collection (in large part) with my meteorite sales to other collectors. I've also had to sell off some of my telescopes and eyepieces to offset the loss in the meteorite sales. Despite this rough patch, I am not tempted to start selling on eBay. For me, eBay is a venue for buying only. This recent sales drop has taught me two things - one, I need a larger customer base. And two, I need to diversify my offerings. To address the first point, I am going to start advertising in larger venues. I have a print ad coming out in a major national publication next month. And I plan on resuming in person meteorite sales at outdoor events like flea-markets, arts and crafts shows, sidewalk fairs, and other targets of opportunity as we chance across them in our RV travels. To address the second point, I am going to start offering a larger selection of specimens that is not limited to micromounts (which is the bulk of my inventory). And I am going to start offering fossils, trinitite, rare minerals, custom-made displays, and meteorite-related artwork created by my wife. I have read with great interest some of the market commentary in this discussion from the larger long-time dealers. And from an observer's perspective, I agree with most of the points Mike, Dean, Alex, and others have made regarding the types of meteorites and their respective price points. Honestly, I don't see how some of you are making any money by selling on eBay. Don't get me wrong, I am not against it, since I have gotten some great deals on eBay recently - including a $2 angrite, several grams of CV3 for under $10, and an ALH Antarctic for under $10. WOW! But seeing margins like this is not inspiring me to emulate the sellers. This truly is a buyer's market - now I just wish MY buyers would start buying! LOL Best regards and clear skies, MikeG .

Re: [meteorite-list] South Pole Meteorite????????????
I completely agree with Jason here. This type of weathering is typical of Antarctic/Ice meteorites. I checked the story behind the Antarctic vessel and it is true. The Hero now resides in Newport, Oregon - the same location as the seller and was sold as surplus many years ago. If the story is true, the buyer needs to do some serious research and find out why this material was left behind, which is the part of the story that doesn't make any sense. I actually tried bidding on it, figuring the detective work might be intriguing and Newport isn't too far from me. It was probably worth the gamble. I look forward to hearing more about this story and what may come out of it. The material looks similar to 76009. Many kilos were recovered and some pieces were taken by helicopter pilots as souvenirs. The new owner has a lot of detective work to do. This crazy story reminds me of another sloppy/unbelievable auction from a few years ago. It was a purported hatch decal removed from the Apollo 13 capsule after flight. The auction story seemed absurd and was a sloppy listing. It was also listed at a penny with no reserve. To make a long story short, it turned out to be the actual decal, which was removed when the Apollo 13 capsule was lifted out of the sea and was removed by one of the recovery ship workers. The buyer of that decal rolled the dice and got an unbelievable bargain and piece of history. Best, Mike Bandli -- Original message -- From: Jason Utas [EMAIL PROTECTED] Hola Darren, All, The story may be crazy, but that meteorite shows weathering exemplary of Antarctic meteorites.

[meteorite-list] What've I got here?

Since they were cheap (a few dollars-- less than $10) I bought them, barely glanced at them (they were small and underwhelming) and set them aside. I found them again recently and have been giving them a closer look. Any ideas what I have here?

Re: [meteorite-list] South Pole Meteorite????????????
Hi, All, The story may be crazy, but the Antarctic Research Vessel Hero is not. Here is an excellent website about it history and its retirement life since leaving Palmer Station: http://www.palmerstation.com/hero/index.html The Hero is currently to be found in Newport, Oregon. It has passed through the hands of several private owners and extensive repairs and renovations have been made. It was moored at the Newport docks, but this year was moved to a less accessible location in the Bay. It may or may not still be owned by a gentleman named Bill Wechter. The R/V Hero has a length of 125 feet and a breadth of 30 feet 4 inches. She displaces 300 tons, with a draft of 14 feet. Her range under power of the 760 hp engine is 6,000 nautical miles at 10 knots. The sails were used for silent running. Meteorites being dense and heavy, I would think they would make a fine ballast for a vessel in heavy seas, and Antarctic waters would qualify in that respect. How many of those useless big black rocks did they chunk down in the bottom of the hull, do you suppose? Anybody on the list live in Oregon? [Insert the smiley emoticon here.] Sterling K.

Re: [meteorite-list] Question About Potassium-Argon (K/Ar) dates for North American and Australasian Tektites
Michael list, Greetings from Tanzania! Sorry to be so out of touch, but electricity and internet service are both pretty insecure here. Michael, K-Ar and Ar40/Ar39 techniques are not limited to volcanic rocks. Anything containing potassium (certainly including tektites) can work. There are always interpretative issues, but that's another subject. I spend a fair bit of my field time here working with geochronology where 2.8 billion years is young and an error bracket of +/- 40 million years is almost too sloppy to be of use! I'm learning some new stuff. No meteorites so far, and virtually no decent search environments. I found a killer little iron in the middle of a jungle trail a while back, but a quick zap with a Niton portable XRF unit showed no Ni. Just a nice chip off of an iron plow or sledge hammer---. The Niton ray gun is driving me crazy. At virtually no cost, I can pull the trigger and analyze for the entire periodic table heaver than Na in less than 1 minute. This machine should be able to let us non-destructively differentiate iron meteorites, and maybe tektites. Why am I going crazy? ALL my collection is in storage in the USA and I can't test the technology! The unit costs around $35,000 US. Here, now, I have unlimited access to one, and soon, several. Imagine being able to instantly (in relative terms), go though a collection of irons and verify their identity. I've got some in my collection that are potentially with the wrong tag, and I bet every museum in the world fits into that fellowship. What if we can easily zap tektites to confirm/differentiate Ivorites, Bediasites, and Australasians? Authenticate moldavites and reject etched glass? I THINK this tool is in our hands now. I'm coming to the US at Christmas time. Who can offer me a nice wide variety of approx. 1 cm sq slices of irons at a decent price? I could even return them afterwards (subject to the risk of confiscation in customs somewhere---). If this works as I think it could, I'd consider buying a Niton on my return to the USA, and offering verification services. If anyone is able to provide me with a dozen or so little iron chips (for a price of course), please let me know. This could be very cool.

Gee, this looks an awful lot like ALHA76001, to name a specific Antarctic meteorite! Compare the photo of a larger slice of ALH 761 in Japan with the ebay photo: http://metdb.nipr.ac.jp/Data/ALH761/sALH-761.1-80_small_200822195950.jpg For several years, I have wondered what happened to the 3800 g piece of this meteorite, which was supposedly once in the Field Museum collection in Chicago (according to MetBase). However, that meteorite and its siblings from 1976 have not been in the Field collection for a long time. Is it possible this is it? Maybe one of you knows the history of these meteorites well enough to speculate.

Here is another view of 76001 @ NIPR: http://metdb.nipr.ac.jp/Data/ALH761/sALH-761.1-79_small_20082219597.jpg The back has patches of crust, but doesn't look anything like the more fresh and intact crust on the eBay material in question. 76001 was a 20.1kg stone, so it is possible that it had a broken side. I'm away from my photographic catalogs, but maybe someone else can check their own. I believe either the Catalog of Yamato Meteorites or Photographic Catalog (1981) show the entire mass. I'll check when I get home... Mike Bandli -- Original message -- From: Jeff Grossman [EMAIL PROTECTED] Gee, this looks an awful lot like ALHA76001, to name a specific Antarctic meteorite! Compare the photo of a larger slice of ALH 761 in Japan with the ebay photo: http://metdb.nipr.ac.jp/Data/ALH761/sALH-761.1-80_small_200822195950.jpg For several years, I have wondered what happened to the 3800 g piece of this meteorite, which was supposedly once in the Field Museum collection in Chicago (according to MetBase). However, that meteorite and its siblings from 1976 have not been in the Field collection for a long time. Is it possible this is it? Maybe one of you knows the history of these meteorites well enough to speculate. Jeff Jason Utas wrote: Hola Darren, All, The story may be crazy, but that meteorite shows weathering exemplary of Antarctic meteorites. Note the thin cracks - almost certainly lined with evaporites, hence the white lining. Also note the fresh exterior and weathered interior. Bassikounou? Nothing like it. More like Antarctic material, to be frank, which, other than ice-blasting, typically shows little-to-no external weathering and varying degrees of internal oxidation. It is a crazy story, but, to be frank, it's either a fresh stone from a salty terrestrial environment that's been laying around for a very short time in very wet conditions, or it is, in fact, from an ice field (somewhere). I've never seen such weathering features on a meteorite from...anywhere else. Have a look at those pictorial catalogs of Antarctic meteorites if you don't believe me - you'll see what I mean.

Re: [meteorite-list] Question About Potassium-Argon (K/Ar) dates for North American and Australasian Tektites
Hi, Paul, List Potassium Argon Dating has been applied to tektites since the method was first available. It dates the arrival date of the tektite, the time of the last secondary melt that resets the K-Ar clock. The arrival date of each strewn- field is the same; the arrival date of each strewnfield is different from the others. The date of the primary melt of all tektites, their formation date (by Rb-Sr isochron), is the same -- about 450+/-50 million years. And their initial 87Sr/86Sr ratio, which is what the isochron points at, is different that any other material in the solar system yet examined by us; their original source is unknown. Guy Heinen's Tektites is the most recent complete work on the subject, published in 1998. It has a complete (up to that date) bibliography of the scientific literature, many 100's of references. Hal Povenmire's books are still available. Going back, there's John O'Keefe's 1976 book, Tektites and his many papers, some of which are listed: http://en.wikipedia.org/wiki/John_A._O'Keefe It appears that the complete text of O'Keefe's 1976 book is online! (There will a short delay while I download the entire thing): http://originoftektites.com/index.php I'd forgotten about Chap. 6. Take a look at Chap. 6, Paul; there may be enough recent bulk compositional data for you. (Putting this on the web must be a new project; Chaps. 7-10 are incomplete, and the References are empty.) It's copyright- free, though. The largest source for bulk composition data of a large number of tektites is: J.A. O'Keefe, Editor, Tektites, Univ. of Chicago Press, Chicago, Illinois (1963), Long out of print, hard to get, costly, though there are xeroxes that sell for $90-$100. It has pages and pages of these analyses, performed by the USGS, in the course of which they destroyed about 8000 tektites. In the pre-Apollo space boom, O'Keefe, who believed in the lunar volcanic origin of tektites, got the US government to spring for this massive study. Dates are based on hundreds of samples. A List of sources from this website (lots of list members there): http://www.meteoriteassociationofgeorgia.org/GATektitesList.htm chosen for their relevance to Georgiaites: Tektites: A Cosmic Enigma, by Hal Povenmire Tektites in the Geological Record: Showers of Glass from the Sky, by G. J. H. McCall Rocks from Space, by O. Richard Norton Tektites: Witnesses of Cosmic Catastrophies, by Guy Heinen Moon Trip, by Bert King Georgiaites, the New Georgia Encyclopedia Bediasites / Georgiaites, by Aubrey Whymark Georgia Tektites, by Paul Harris Upper Eocene impact horizon in east-central Georgia, R. Scott Harris A prominent recent researcher is Billy Glass. Yeah, I know... He's an authority on tektites and his name is Glass. And everybody calls him Billy Glass, not William. Google Billy Glass Don't want to forget the late Darryl Futrell: http://www.meteorite.com/Darryl_Futrell/ One of Darryl's papers is referenced in: http://www.edamgaard.dk/Bibliography_final.htm That bibliography is excellent for the entire subject of tektites, but only covers Australites. You could Google for tektite potassium argon dates and get 2380 hits, but you will have to dodge Young Earthers. Here's some GoodGoogles: A very geological take: http://www.utexas.edu/tmm/npl/meteorites/tektites/tektite_info.html Vergil Barnes was an important pre-radiometric researcher of tektites. Also George Baker, who first explained the origin of the shapes. 1999 text on Geochronolgy by K-Ar, pp. 35-36 http://books.google.com/books?id=FgeSnj9OnFsCpg=PA35lpg=PA35dq=tektite+potassium+argon+datessource=webots=-Yq2NQj1Q8sig=-3fOLu7vkys2lUJwceWJdEIMd5ghl=ensa=Xoi=book_resultresnum=6ct=result They say few K-Ar data-sets are as concordant as the K-Ar of tektites, and it's true. In general, there seem to be few quarrels about these dates. Or are there? http://www.australites.com/theories.htm In Conclusion: To anyone who has worked with them, tektites are probably the most frustrating stones ever found on earth. -- Henry Faul, 1966 The Tektite: 1. Never was there so much data with so little return in certainty. 2. Every researcher, in his heart, believes all the other researchers are wrong, and every one of them, however associated in schools, have theories that contradict the others. 3. The last time I compiled a list of all the proposed theories-of-origin, there were eighty-three of them. 4. Dr. Geoge Seddon remarked, When first hearing of tektites, I thought them quite incredible. But after learning more, I realize they are impossible. 5. If you research them long enough, you too will have yet another theory of tektites, incompatible with all the others. Sterling K.

[meteorite-list] Question About Potassium-Argon (K/Ar) dates for North American and Australasian Tektites
Dear Friends, Can anyone recommend a publication that provides a comprehensive listing of Potassium-Argon (K/Ar) dates that have been published for the North American and Australasian tektites? Also, what the authorative reference(s) work for the bulk composition of tektites from each of these strewn fields? Any citations, which you can recommend would be greatly appreciated.
