Excellent post, Gary I copied the selections and found I have many, but there were some that I would like to have in hand . I do agree however that, much to the distate of many old school purists, the days of the book are numbered as far as the publication of new materialis concerned. When I drive by the expensive to construct and maintain public libraries in Las Vegas...and were not talking about great university, or national, repositories here...I wonder if my tax dollars couldn't be spent more effectively.

Re: [meteorite-list] Guide to Newbies (was Meteorites Competition)
Hi List, I think MikeG understands the concept, and if Jim Tobin already has material covering the subject, it's probably not worth the time putting it in book form. But none of the books below touch on the subject I'm touching on. The newest Norton book does give a great explanation for nickel testing, determining bulk density and etching meteorites. The idea isn't about meteorite hunting/people, the origin of meteorites in space, a catalog of meteorite types (or the history of the XYZ fall), but a detailed, step-by-step guide for cutting, polishing, treating meteorites, so as to ensure that people can reduce waste. It wouldn't be a heavy, big book. I have such a guidebook on casting, which is wire bound, and is smaller, much lighter than 99% of my meteorite books. Eric's suggestion made me laugh! I think he's right, maybe it would be good to just put the existing material into Meteorite Wiki! Anyways, what touched off the discussion was a question about exchanging money and stones with people in Morocco, and wasn't a question about meteorite prep. I just thought that I've seen many newbies have a lot of questions like that. And someone attacked newbies for asking questions on cutting, etching, etc. And when Adam Hupe reminded us how precious the material really is, it made me wonder just how much material has been damaged by novices experimenting with lapidary equipment. I've seen people soak stones in acid to expose the metal (terrible outcome...). Anyways, thanks for the feedback everyone. Happy hunting/collecting (and selling). And keep the thought provoking questions coming you newbies! have a great day!

Re: [meteorite-list] Guide to Newbies (was Meteorite Competition)
Hi Gary and all, If listee's read about the Port Orford Meteorite Mystery by Roy S. Clarke and Plokin they should also read the article in Meteorite Magazine, May 2007 by Doug Borgard. Borgard covers a lot of items that I have maintained about the Port Orford Meteorite over the years and shows many of the flaws that are in the Port Orford Meteorite Mystery. I didn't necessarly agree as much with the second part as much as I did with the first part but it is another view on the Port Orford Meteorite which I view as real. Here are my views expressed back in 2007 about his article: In the May issue of Meteorite Magazine, there is an excellent article about the Port Orford Meteorite by Doug Borgard. Doug relates many of the issues I have brought up over the last several years in regards to the official Publication that it was a hoax. While it may have been a hoax, I think that Doug's article has exonerated John Evans, who I feel did his part and was an innocent party to this allege hoax. There is a second part that will be published in the August issue of Meteorite. Don't know what Doug will say but if he has found some of the same material that a friend of mine who research this very thoroughly, there may be reference to Jackson who in my opinion had been unfairly treated at that time. He was undermined by those he hired and lost a job from the government. It is my believe that he had reasons to plant the imilac in place of the newly found Port Orford pieces. Perhaps he wanted to search, recover, or find this for himself and sell it to the government to make them pay. There is certainly a motive here. There are other scenarios also. In this article I believe that the real truth of the matter is brilliantly argued, mistakes by writers of the John Evans and the Port Orford Meteorite Hoax are cut to the bone and that a better explanation is given. One of the mistakes the investigator made was being on the wrong mountain. No wonder they didn't find anything. While I maintain this still could be a hoax, I in no way believe that John Evans had anything to do with that and better research was needed to explain things than was done. I look forward to the next installment of Doug's article. --AL Mitterling - Original Message - From: Gary Fujihara fuj...@mac.com To: Dennis Miller astror...@hotmail.com Cc: meteorite-list@meteoritecentral.com; impact...@aol.com Sent: Sunday, November 15, 2009 11:32 PM Subject: Re: [meteorite-list] Guide to Newbies (wasMeteorites Competition) Aloha Dennis, Anne, listees, The Port Orford, Oregon Meteorite Mystery, Roy S Clarke, 1993 Smithsonian Press, 42 pg Great story of an even greater hoax __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] newbies coming out of the woodwork
Hi Steve and all, I think I would like to point out that people and newbies should be careful when accepting items from you. You have been buying some of your items from someone who was misrepresenting meteorites and was pointed out on this list. It would be nice of you if you were to point out to anyone accepting these free meteorites that they came from this person of very questionable reputation. My suggestion is not to buy from him so we don't get material that is of questionable pedigree into our collections. --AL Mitterling - Original Message - From: steve arnold stevenarnold60...@yahoo.com To: meteorite-list@meteoritecentral.com Sent: Monday, November 16, 2009 8:31 AM Subject: [meteorite-list] newbies coming out of the woodwork Hi list and all.

[meteorite-list] Info on Sikhote Alin's shrapnel
Hi all, I ask to those who are more experienced than me,clarification about Sikhote Alin's splinters formation. In my opinion there can be two ways to justify the origin of the fragments found in the vicinity of the largest craters, 1) The kinetic energy released at the contact surfaces of meteorite/ground was enough to melt the frontlayer of the meteorite with the subsequent violent expulsion of fragments, fused or partially fused. 2) Having the meteorites reached the retardation point at only 5 km of altitude, they would arrived at an impact with their hot surfaces, this would facilitate the expulsion of splinters.

(I had to state the obvious) What type of bait do you use? http://www.urbandictionary.com/define.php?term=baitpage=4 and; feeding fish (sharks, carp, suckers, etc.) are in schools (shoals, drafts, runs, hauls, or catches) and not droves. Droves might be used for: 1 : a group of animals driven or moving in a body http://www.merriam-webster.com/dictionary/droves or 2 : a large number : crowd —usually used in plural especially with in came in droves . The person throwing the bait (fish guts, fins, and heads; in your case orphaned or mongrelled meteorites) is caller a chummer or baiter. And the act of throwing the chum is called chumming or baiting. So Steve, keep on chumming / baiting so the chiming doesn`t stop. Have a great day Steve and All.

[meteorite-list] Rosetta Bound for Outer Solar System After Final Earth Swingby
http://www.esa.int/esaCP/SEMZC04VU1G_index_0.html Rosetta bound for outer Solar System after final Earth swingby European Space Agency 13 November 2009 This morning, mission controllers confirmed that ESA's comet chaser Rosetta had swung by Earth at 8:45 CET as planned, skimming past our planet to pick up a gravitational boost for an epic journey to rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. Rosetta passed over the ocean, just South of the Indonesian island of Java, at exactly 08:45:40 CET, at a speed of 13.34 km/s with respect to Earth at an altitude of 2481 km. The swingby was pre-planned and fully automated, and the spacecraft was in direct communication with Earth at the time, via the ESA New Norcia Station. The successful swingby was confirmed at 09:05 CET when mission controllers re-established contact with Rosetta via ESA's Maspalomas station in Spain. Although a detailed analyses is in progress, spacecraft operators have confirmed that the swingby provided a boost of 3.6 km/s. Europe's comet chaser has now flown a little over 4500 million km of its 7100 million km journey to its destination comet 67P/Churyumov-Gerasimenko. This was Rosetta's fourth planetary swingby and the third and final swingby of Earth. [Image] Image of Earth beamed back by Rosetta last night Science close to Earth Some of Rosetta's instruments have been on since early November, performing imaging, magnetospheric, and atmospheric observations, as well as looking for water on the Moon. The first round of images and data recorded just before and during the swingby will be downloaded later today. Rosetta is now departing Earth to meet asteroid (21) Lutetia in July 2010. It has gained sufficient orbital energy to achieve its final goal: a rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. The spacecraft is scheduled to enter deep-space hibernation by mid 2011 for the coldest leg of her journey to receive a wake up call only in spring 2014.

But fall location duplication can be quickly dismissed as random chance, since there is no connection between earth-crossing asteroid orbital periods and earth's rotational period. However, date-synchronized falls ~is~ a possibility. Dr. Rubin and I wrote a paper on this subject which appeared in the journal _Earth, Moon and Planets_ in April 2008: http://www.springerlink.com/content/fh155p1n30318876/?p=c33955927db24de 2b0c2116738abeb6dpi=0 Our conclusion was that due to the tiny fraction of meteorite falls that are successfully recovered each year, and the comparatively short dynamical lifetime of a meteoroid stream (10^4 to 10^5 a), the probability of successful recovery of two falls from the same stream are extremely small. --Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com on behalf of ma...@imagineopals.com Sent: Sun 11/15/2009 12:20 PM To: meteorite-list@meteoritecentral.com Subject: Re: [meteorite-list] new fall RICH friday 13 / 11/2009; ; 21.25 cmt could there be a cloud of objects that Earth's orbit flys through?

[meteorite-list] Leonid meteor shower to peak Tuesday
A reminder - Greg S. http://www.cnn.com/2009/TECH/space/11/16/nasa.leonid.meteors/index.html (CNN) -- This year's Leonid meteor shower will peak early Tuesday, forecasters say, producing mild but pretty sparks over the United States and a more intense outburst over Asia. We're predicting 20 to 30 meteors per hour over the Americas and as many as 200 to 300 per hour over Asia, said Bill Cooke, of NASA's meteoroid environment office. Our forecast is in good accord with ... work by other astronomers. The Leonid shower is made of bits of debris from the Tempel-Tuttle comet, which streaks through Earth's inner solar system every 33 years. It leaves a stream of debris in its wake. Forecasters, however, say it's hard to know exactly how many of the meteors will be visible. We can predict when Earth will cross a debris stream with pretty good accuracy, Cooke said. The intensity of the display is less certain, though, because we don't know how much debris is in each stream. The first stream will cross over Earth about 4 a.m. ET. That stream should produce about two or three dozen meteors per hour over North America, NASA said. Experts say people who want to watch the shower, which is visible with the naked eye, should get as far away from city lights as possible. The darker the sky, the brighter the meteors will appear. Leonids will appear to be shooting almost directly out of the planet Mars. High-altitude sites are best for viewing, reducing glare from the moon, and there's no particular direction one should look for the best shot at seeing one, they say. The next Tuesday streams will peak over Indonesia and China shortly before dawn there. The pair of streams there were actually laid down by Tempel-Tuttle in A.D. 1466 and 1533, and the two of them crossing at the same time is the reason for the 300 or so visible meteors expected. Even if the rates are only half that number, it would still be one of the best showers of the year, Cooke said. Overall, and especially in the United States, this year's Leonids are mild. From 1999 to 2002, the streams produced outbursts of more than 1,000 meteors per hour. But one added plus this year, Cooke said, is that, coincidentally, Mars will be passing nearby at the time of the showers. Leonids will appear to be shooting almost directly out of the planet Mars, he said. _ Hotmail: Trusted email with Microsoft's powerful SPAM protection. http://clk.atdmt.com/GBL/go/177141664/direct/01/ http://clk.atdmt.com/GBL/go/177141664/direct/01/ __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] earth rocks that contain nickel
Dear List, With all the recent attention put on newbies I thought now would be the perfect time to ask something stupid. My Question: What Earth rocks naturally contain nickel? The reason I ask is I have found some rocks that test positive for nickel. I have used the Nickel allergy test, the cotton swab turned pink and stayed pink for more than 5 minutes. When researching this nearly every source I have found says nickel inside of earth rocks is very rare and a good sign for positive meteorite identification. The rock in question: - has a black crust (not as nice as I would expect), - it has a bulk density of 3.6, - it has shiny, small metal flakes on inside - it is magnetic, - it does not leave a streak - it tests positive for nickel - it is not slag (no vesicles, stony gray interior) I do not think this is a meteorite because the interior looks like ingenious rock and I have not been able to find meteorite pictures that look similar. So what I'm really trying to do is get a list of earth rocks together that do contain nickel so that I can ID it off of one of them (and ignore it in the future if I come across it again). I have read this page: http://en.wikipedia.org/wiki/Nickel and the samples on that page, limonite, garnierite, pentlandite don't seem to match up with what I have here. Here is a picture of the rock in question: http://www.mikesastrophotos.com/rocks/nickel-rock.jpg Thanks, Mike From University of Washington 'Gallery of meteor wrongs...' With a few rare and well known exceptions, naturally occurring terrestrial rock do not contain iron metal or iron-nickel metal. There are two reasons. First, early in Earth's history the iron-nickel metal sank to form the Earth's core. Second, any metal that did not sink has oxidized (rusted) over Earth's long history. The Earth's environment is far more oxidizing (oxygen atmosphere and water) than space, where meteorites originate. Earth rocks do contain iron and nickel, but only in oxidized (non-metallic) form. Therefore, if you find a rock that contains iron-nickel metal, it's probably a meteorite. That sounds simple, but there are two problems. First, many people find slags and other by-products of metal manufacturing. Some of the samples that have been brought to us may have been from forges or blacksmith shops that are more than 100 years old (see meteorwrongs 026, 027, 061, 065, 070, 075, 093, and 122). Others appear to fall from the sky for unknown reasons (see Getafe). Metal in slags and industrial by-products is mostly iron. Such materials will probably contain little nickel (much less than 1%). So, if you can determine that the sample has little or no nickel, then the sample is not a meteorite. The second problem is that some minerals in terrestrial rocks look like metal but are not. All that glitters is not metal. Many rocks contain small grains of sulfide minerals like pyrite (fool's gold) or micas that are finely disseminated and shiny. I've had many people tell me, But, it contains metal! when there really isn't any. Clue: If there are shiny bits in it but it's not magnetic, it's not a meteorite (Meteorite Realities). __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] YD impacts: isotopes, image?, Carolina Bays, and AD
Hi Paul, Rich - I am sceptical of Firestone's claim of supernova as the production mechanism for the isotope variations observed. As an alternative, my GUESS (hypothesis) is that neutrons and protons are freed in large hyper-velocity impacts. This should be a relatively easy hypothesis to check. If I am correct about one spike in the INTCAL98 chart, then Barringer crater in Arizona should be surrounded by unusual isotopes. Or it may be that deuterium or tritium in comets is the material from which the neutrons and protons are freed; I have no idea whether nucleon binding energies vary from element to element, or from isotope to isotope. In any case, since my stroke all of this kind of work is beyond me. If any list participant wants an image of what may be a Native American petroglyph showing this impact, or at least a cometary impact, please contact me off list. On the Carolina Bays, there appears to be evidence for an impact mega-tsunami hitting the east coast of North America around 1,050 BCE. This may be reflected in the Carolina Bays' distribution and their contents.

The Sudbury impact, named after the Canadian city located near the center of what remains of the ancient crater, happened around 1.85 billion years ago (SN: 6/15/02, p. 378). Despite erosion since then, the impact structure at least 200 kilometers across is recognized to be the second-largest on the face of the planet, says William Cannon, a geologist with the U.S. Geological Survey in Reston, Va., and coauthor on a paper in the November Geology. The event fundamentally affected the concentrations of dissolved oxygen in the deep sea enough to almost instantly shut down the accumulation of marine sediments known as banded iron formations, report Cannon and coauthor John F. Slack, also of the USGS in Reston. Banded iron formations, massive deposits rich in iron oxides, have accumulated at several periods in Earths long-distant geological past, mostly when atmospheric concentrations of oxygen were low (SN: 6/20/09, p. 24). One extended episode of banded iron formation (or BIF) buildup suddenly and without an obvious explanation ended about 1.85 billion years ago, says Cannon. Over a very short interval, he notes, the environment shifted from one happily making banded iron to one that wasnt. In northern Minnesota and other areas nearby, the formations lie directly underneath a thick layer of material only recently recognized as ejecta from the Sudbury impact. Mark Jirsa, a geologist with the Minnesota Geological Survey in St. Paul, was a member of the team that identified the ejecta layer. We intuitively connected the Sudbury impact with the shutdown of BIF accumulation, he says. But now [Cannon and Slack] have come up with a model for how that might have happened. About 1.85 billion years ago, Earths now separate landmasses were joined in a single supercontinent. That also means there was one large ocean, says Cannon. Many scientists suggest that the object that slammed into Earth then probably an asteroid abut 10 kilometers across splashed down in that ocean, in waters about 1 kilometer deep on the shallow shelf surrounding the supercontinent. Models hint that the tsunami spawned by the event would have been 1 kilometer tall at the impact site and remained at least 100 meters tall about 3,000 kilometers away, Cannon adds. Those immense waves and large underwater landslides triggered by the impact stirred the ocean, bringing oxygenated waters from the surface down to the ocean floor, the researchers propose. Sediments deposited on the seafloor before the impact, including BIFs, contained little if any iron in its Fe(III) form but were high in Fe(II), a sign that most parts of the ocean were oxygen-free. But marine sediments deposited after the impact included substantial amounts of Fe(III) but very little Fe(II) and, therefore, sizable amounts of dissolved oxygen. The teams analyses suggest that after the impact, dissolved iron spewed into the deepest parts of the ocean by hydrothermal vents would have reacted with oxygen within a day or so, thereby choking off most of the supply of Fe(II) to shallower waters where BIFs typically accumulated. While Cannon and Slacks model explains how BIF accumulation might have suddenly ceased 1.85 billion years ago, it doesnt prove thats how it happened, Jirsa warns. Nevertheless, he notes, scientists are closer to an explanation than we previously were. The geological record suggests that environmental changes were happening in oceans worldwide even before the Sudbury impact, he adds, and the role that the impact played, if any, in shutting down BIF accumulation isnt well understood. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Absolutely fantastic, Graham...love that! Thanks to you, Graham, and to the many others for sending kind words about Michael Johnson's post of my photos earlier today. But I must say that ANYONE here on the list can do this -- and that's the reason I ask Michael to post these little hints from time to time ;-) Thanks again Michael, not only for throwing a little educational outreach into your mix, but also for everything you do to keep bringing us RFSPOD!

Re: [meteorite-list] Carolina Bays
Hi Paul - In my opinion, as far as the Carolina Bays are concerned, they are a nothing more than a time-consuming red herring of gigantic proportions. Even if the Carolina Bays are impact features of some sort, they clearly are much too old be connected in anyway with a Younger Dryas event. In this case, I would think that the thing to do would be to look for another Kitscoty type structure indicating impact with an ice sheet. In his most recent summary, Firestone showed another set of what he views as secondary impact craters, but these with a different directional foci, i.l. from a different impact. Otto Muck was probably the person most responsible for popularizing the notion of the Carolina Bays as impact structures, but he saw them as the result of an mega-tsunami from an impact in the Atlantic Ocean. Myself, I am still waiting for the USGS cores from the Carolinas. E.P.

Re: [meteorite-list] YD impacts, agan
Hi Darren - You pretty well summed it up. Firestone's earlier hypothesis have been all over the place. I know this may sound strange to you, but when you're doing cutting edge research you can make mistakes. Note that responsible researchers disagree with McSween on the number of parent bodies for meteorites. I suppose that all of this is what happens when a nuclear physicist becomes involved in trying to explain impact data, and having no one to help him. It's really a shame the Dr. Peiser took the Cambridge Conference over to Global Warming Scepticism, otherwise all of this would have been hashed out a long while back. It's also a shame the Shoemaker died in that auto accident. He was the best the USGS had. Finally, it's a shame that NASA spent no money studying recent Earth impacts, but instead wasted it on the Ares 1. The interesting part in all of this is how many new unsuspected impacts are being evidenced by those involved with Firestone. We now have two, one in Alaska, another in Siberia. And the other ice impacts indicated by the orientation of secondary impact craters. As far as the injection mechanism goes, I'll stay with Clube and Napier for the time being, and forego the supernova hypothesis. Which leaves me with those isotopes to explain... But the bottom line is that 90 to 95% of the people living in North America died at 10,900 BCE, and those that survived left their descendants memories of what had occurred. In closing, even I myself have been wrong in the past, and I retain the right to be wrong both now and in the future. PS - someday impactites from the YD event will come on the market. E.P. Grondine Man and Impact in the Americas Darren wrote: Okay, a review-- so far this impactor has been a 500 mile wide snowflake from the atmosphere of a supernova hitting at hundreds of kilometers per second. It has been an airburst over ice leaving no crater. It has left craters deeper than Death Valley in the Great Lakes. It has caused golden showers and a rain of diamonds that lasted for months. It shotgun-blasted iron particles into the tusks of mammoths. It has been a comet. It has been a chondrite, and all meteorites found by or through Nininger have been debris from it, so it was actually all types of chondrite and everything else Nininger collected. Now, it is an extrasolar lunar meteorite from the future. So, to sum it up, this 500 mile 10 mile very low-density metal and stone filled comet-asteroid supernova-produced lunar snowflake that struck at hundreds of kilometers per second did and didn't produce impact craters and left no marks except for the Great Lakes and thousands of very shallow overlapping, highly oblong pits exactly like craters from an impact event except for craters from an impact event rarely being very shallow, overlapping, highly oblong pits. It killed off all the lost Ice Age fauna at once, except for all of the Ice Age fauna, which went extinct at different times in different locations and spread out over thousands to tens of thousands of years (in some spots pretty darn well timed with the establishment of human populations, coincidence or no.) Oh, and somehow a supernova is still involved. That isn't refining an idea-- that is throwing everything you can think of against the wall and hoping that some of it sticks. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Info on Sikhote Alin's shrapnel
List, I have searched many Kilos of SA shrapnel without ever finding ONE without some surface melting. From what I have seen shrapnel is ALL air shredding with subsequent atmospheric frictional melting. Cheers, Fred Olsen -- Original message -- From: ensorama...@ntlworld.com I did not know heat was needed at all to form shrapnel...surely it is just due to shearing of fragments from the dramatic collisions of fragments on impact or during exposive events on the way down that did not leave enough time for ablation? Graham UK Maurizio Eltri maurizio.el...@libero.it wrote: Hi all, I ask to those who are more experienced than me,clarification about Sikhote Alin's splinters formation. In my opinion there can be two ways to justify the origin of the fragments found in the vicinity of the largest craters, 1) The kinetic energy released at the contact surfaces of meteorite/ground was enough to melt the frontlayer of the meteorite with the subsequent violent expulsion of fragments, fused or partially fused. 2) Having the meteorites reached the retardation point at only 5 km of altitude, they would arrived at an impact with their hot surfaces, this would facilitate the expulsion of splinters. I apologize for my bad English.
