Re: [meteorite-list] Meteorite Picture of the Day
Thanks for the Post Paul and Fred! Very interesting that it was called a stony-iron probably just due to the inclusions - and furthermore that all stony-irons rather than the colorful olivine types were apparently called pallasites at that time (1924?) and this isn't just an artifact on the Ward's label, does anyone know when the definition of a pallasite was standardized ... or has it just gradually slid into the current Esquelesque usage?

In Meteorite with coin embedded at http://six.pairlist.net/pipermail/meteorite-list/2011-October/080158.html Yinan Wang wrote, Here is a funny little piece for laughs: Iron meteorite with a coin marked Vittorio Emanuel, Italia.

Victor Emanuel II, first king of a united Italy. Size: 2 3/8 D Weight: 2oz Condition: Very good” Yes, it is amusing the different types of objects, which get confused and mislabeled as a “meteorite.” Judging from the coin and picture, this object is a tourist curio that people visiting Mt. Vesuvius once could buy as a souvenir of their visit. Back in the 1800s and as late as the 1930s, a person visiting Mt. Vesuvius, if they had right guide, could for a small fee give him or her a coin and the guide would with the aid of metal tongs snag a piece of semi-molten lava from an active lava flow and embed a coin in it as you watched. My mother, when she was in Italy during the 1930s, paid her guide to create such a souvenir from a coin that she had and lava. My sister currently has this curious souvenir. An example of such souvenirs is illustrated in “Fascist coin embedded in lava” at: http://www.bbc.co.uk/ahistoryoftheworld/objects/cPGBddLLRTKFvEuerO6ulg This practice is noted on page 104 of: Scott, David Dundas, 1856, Italy, classical, historical and picturesque.

Shall Without fall do drank up in the near future. The Photo you will show. Thank you for advice! MexicoDoug mexicod...@aim.com [Mon, 3 Oct 2011 14:32:40 -0400 (EDT)]: Hello Alexandr Continue searching you must find something good soon! The first link is an earth rock, but it is most similar to a lunar meteorite dues to the brecciated appearance, with some white and green-like possible. But there is a quartz vein (a long mineralized branch of high pressure formed terrestrial quartz), so it is no good. The second picture has nothing remarkable. The third picture has some possibility as a weathered chondrite meteorite. We must know the other stones in that place you found it to determine easily if it is similar to them which is a first filter. Also, you will need to cut ort break off a small piece to see inside the stone where we can determine morer easily what it is. In the present complete state, it can be only a sand-blasted, worn surface weathered from the desert of a terrestrial (earth) stone, we cannot be sure. The fourth picture link, like the third could be interesting, but we need to look inside. The weathering (wear) from the climate and time make it difficult to determine. It is possible that the brown spots are caused by oxidation of iron inside which could be meteoritic. But we need to see inside, by sawing or breaking off a piece and looking at the matrix of the rock. Please keep in contact if you find anything also, I would love to know! Spaciva!

[meteorite-list] Gold and Iridium content of meteorites (especially irons)
Hi List, In perusing through the latest additions to the Met Bulletin today, I was reading the compositional data for NWA 6932 (iron, ungrouped). I noticed that the gold (Au) content was listed at 1.49mg/g. Is this sort of data as straight-forward as it appears, or is there more to it that this layman is missing? In other words, how much gold is in this meteorite? The TKW of this meteorite is 32kg. So, with 1000g in a kilo, and 1000mg in a gram, how much gold is in this celestial hunk of iron? (my math is horrible) Second question, what is highest known gold content in a meteorite and what meteorite is it? Third question, some meteorites also have high iridium content. What is the highest known iridium content in a meteorite? I am not suggesting in any way that meteorites should be refined or melted down to extract their precious metals content, but given the high value of metals such as gold and iridium, has any profiteer tried such an endeavour? Or would the process be too complex and expensive?

Re: [meteorite-list] Gold and Iridium content of meteorites (especially irons)
...so when we get tough going people will start melting down their meteorites for precious metals. Gold is currently US $50-$60/g. The example you quoted of 0.15% gold, if true (sounds high, but why not, are you sure they weren't micro grams being a factor of 1000 even smaller than you say?) would mean you need to buy about 650 g of this meteorite to extract a gram of gold. So if the meteorite is $5/g you have to pay 60 times the value of the gold just to get the raw material. Then you have to extract it. It would be a bitch to extract it. The sulfides would tangle the gold all up in conventional extration processes. It would be easier to make micros out of a nice meteorite rather than re-invent the Butcher iron! Hope that gives a bit of insight!

Re: [meteorite-list] Gold and Iridium content of meteorites(especiallyirons)
Hi Gang, I was just curious about exactly how much gold is bound up inside a meteorite with a higher than average content, like the one in this example. Personally, I share the same sentiment as most of you - it would be heresy to destroy a meteorite to extract something that is available here on Earth, even if it wasn't cost-prohibitive. At 41 years old, I have made it this far in life with terrible math skills, so this old dog isn't going to take any refresher courses. I was hoping one of the more skilled (and intelligent) members would act as a human calculator and cipher this question for me. :) So in this particular case, the 32kg iron meteorite contains ~1.5 troy ounces of gold, with a current market value of ~$2550. What sparked my curiosity was the apparently high gold content that was measured in milligrams and not the usual micrograms one expects to see. One last question, perhaps rhetorical in a sense, has anyone ever seen gold in a meteorite? I mean, has there ever been a visible bleb or gold inclusion in a meteorite? Or is all of the gold bound up on a molecular level and invisible to the naked eye and 10x loupe? I guess there won't be a gold rush to the asteroid belt Best regards, MikeG -- - Galactic Stone Ironworks - Meteorites Amber (Michael Gilmer) Website - http://www.galactic-stone.com Facebook - http://tinyurl.com/42h79my News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone EOM - http://www.encyclopedia-of-meteorites.com/collection.aspx?id=1564 - On 10/3/11, Sterling K.

Re: [meteorite-list] Gold and Iridium content of meteorites(especiallyirons)
Hi Doug and List, It sounded awfully high to me also, but what do I know? LOL Quoted below is the text from the write-up. Notice, the gold content is the only element listed in milligrams. Here is the text from the Met Bull write-up : Northwest Africa 6932 (NWA 6932) (Northwest Africa) Found: 2008 Classification: Iron meteorite (ungrouped) History: Reportedly found in the Algerian Desert Petrography: Plessitic octahedrite with isolated (5% of area) sparks and spindles of kamacite; longest bands are ~8 mm long and 0.2 mm wide. The material may be reheated; the fine plessite has a granular appearance and there are small dark ellipses that may reflect resorption of phosphide. No heat altered rim was recognized. Stucture Opl. Geochemistry: Composition: 4.51 mg/g Co, 69.8 mg/g Ni, 82.4 μg/g Ga, 380 μg/g Ge, 12.0 μg/g As, 4.12 μg/g Ir, and 1.49 mg/g Au. The meteorite has no close compositional relatives. For example, in the Co range from 6.2 to 7.5 mg/g, no ungrouped iron has a Au content within 20% and only Guin and Laurens County have Ir contents within 20% of that in this iron, but these irons differ in several other compositional respects. Specimens: Several additional masses are known. Best regards, MikeG PS - I am having internet connectivity issues and my connection is running about as well as a 500-pound man right now.

Re: [meteorite-list] Gold and Iridium content of meteorites(especiallyirons)
Hi Mike, Stuart and fellow astrochemisticists, The Bulletin is not a peer reviewed place, it is just the world being held on a few Atlas' shoulders who are nice enough to slave over it and an occasional inaccuracy could happen. Perhaps it was an issue of optical character recognition since mu, the prefix for micro (as in micrograms) looks a lot like an m, if you put your astronomer's cap on you'd suspect that the simple explanation it is just a run of the mill typo that will now be corrected. But ... since we haven't analyzed this meteorite, we can't be sure. For my argument that it is hogwash that this meteorite would have all that gold (so, the bigger picture is, that don't spread the idea that there are up to 48 grams of gold in a 32 Kg chunk of iron meteorite or folks will forget where it came from and the next thing we know the newspapers will be proclaiming that meteorites are loaded with gold). OK my argument, referencing Anders Ebihara, 1982, yes the same Anders that (karmaca) Martin kindly contacted not too long ago who invented the term poor man's space probe for meteorites, showed that in the Solar system there is nearly one hundred-million times more iron than gold in the elemental abundances in the Solar System. Well, if an iron meteorite has in round numbers, 900 mg/g of iron (90%), then moving the decimal over 7 zeros, we get 0.09 mg Au/g, which is 0.009 mg/g which is 9 ug/g. Granted, 9 is off by a factor of 6x more than is reported for the meteorite but at least we are not a factor of nearly 200 off (1500 ug/g = 1.5 mg/g). That's all I can say, based on a nice guy's work from 1982... but I'm less peer reviewed than the Bulletin so we need someone who is closer to the analysis. Or, perhaps go through a bunch of irons with published analyses and just see if anything is over say, 10 ug/g, in which case that would make a far more interesting story than a footnote to an analysis on what star made all that gold and why. Was it the home star of Girl from the Golden Atom? Did their society get obliterated? Did the incredible shrinking ray malfunction when reforming their marriage ring? And what of our adventurous and debonair young and gifted chemist?

Personally, I share the same sentiment as most of you - it would be heresy to destroy a meteorite to extract something that is available here on Earth, even if it wasn't cost-prohibitive. At 41 years old, I have made it this far in life with terrible math skills, so this old dog isn't going to take any refresher courses. I was hoping one of the more skilled (and intelligent) members would act as a human calculator and cipher this question for me. :) So in this particular case, the 32kg iron meteorite contains ~1.5 troy ounces of gold, with a current market value of ~$2550. What sparked my curiosity was the apparently high gold content that was measured in milligrams and not the usual micrograms one expects to see. One last question, perhaps rhetorical in a sense, has anyone ever seen gold in a meteorite? I mean, has there ever been a visible bleb or gold inclusion in a meteorite? Or is all of the gold bound up on a molecular level and invisible to the naked eye and 10x loupe? I guess there won't be a gold rush to the asteroid belt Best regards, MikeG -- - Galactic Stone Ironworks - Meteorites Amber (Michael Gilmer) Website - http://www.galactic-stone.com Facebook - http://tinyurl.com/42h79my News Feed - http://www.galactic-stone.com/rss/126516 Twitter - http://twitter.com/galacticstone EOM -
[meteorite-list] Iron grouping/Harrison Brown/Abundance of Gold, B.W.
This is a good reason to pay respects to Harrison Brown, who was an American meteoriticist born in 1917; worked with the nuclear physicists throughout the War and is the pioneer at the University of Chicago along with the Anders crowd, that gift-wrapped for Leonard (and via osmosis, Wasson) some of their most interesting fields of study. Brown, with his grad student had no top secret responsibilities left after the war and turned to merge his love of chemistry, work with nuclear chemistry to ffirst apply neutron analysis to the classification of iron meteorites and broke the ground for the classification scheme we have today. Way back in 1949, he discussed his results at UCLA and it caught on with the rest of the meteoriticists. He analyzed 45 irons of all types and found the highest gold concentration was: Bear Creek (Colorado, USA) Gold content: 2.5 ug/g (yes, that's micrograms per gram i.e., ppm) (Doug note: well below the 1490 ug/g reported in the Bulletin of NWA 6932) So Mike - that's an oldie but goodie and addresses your question of gold content and pretty much says it’s an error in the Bulletin you were basing this on, without a reasonable doubt. Be fun to compare the values with modern analytical techniques.

Re: [meteorite-list] Gold and Iridium content of meteorites(especiallyirons)
But Doug, Who says the solar system is uniform and that this iron can't have a higher than average gold content? On Earth you certainly have ore bodies that have significantly high gold content (although much less than this meteorite) and then you have areas with no gold at all. Why can't this iron be from a source that just happened to have a higher than usual gold content? Btw, anyone got a sample of this stuff around? -Yinan On Tue, Oct 4, 2011 at 12:31 AM, MexicoDoug mexicod...@aim.com wrote: Hi Mike, Stuart and fellow astrochemisticists, The Bulletin is not a peer reviewed place, it is just the world being held on a few Atlas' shoulders who are nice enough to slave over it and an occasional inaccuracy could happen.
