What does it mean when it says; mg/g etc... Is this milligrams divided by grams? What would the percentage be put in a way that it can be compared with the way others are reported? Geochemistry: Compositional data: Co 6.0 mg/g; Ni 79 mg/g; Ga 24 μg/g; Ge ~80 μg/g; As 29 μg/g; Ir 0.50 μg/g; Au 2.39 μg/g. Data are the mean of duplicate determinations. The composition of the metal differs in detail from other pallasites. For example, the Ir concentration is 0.50 ug/g, with the nearest relative Seymchan at 0.67 μg/g and Barcis at 0.32 μg/g. Classification: On element-Au diagrams, Conception Junction plots distinctly lower than most PMG on Ni and Cu and above most PMG on Co, Ga, As, and Ir diagrams; it is therefore classified as PMG-anomalous (PMG-an). Its Ni and Cu contents are the lowest known for PMG. Its nearest PMG-an neighbor on most diagrams is Krasnojarsk. The low Ni and high Co could reflect unrepresentative sampling of kamacite and taenite but these are the means of two replicates. Thank you.

[meteorite-list] New mineral in NWA 1934 discovered: Brearleyite
New mineral in NWA 1934 discovered: Brearleyite Researchers at Caltech and several author institutions have named a newly discovered mineral in a meteorite, “brearleyite,” in recognition of University of New Mexico Professor and Chair of Earth and Planetary Sciences Adrian Brearley for his contributions to meteorite mineralogy. “I’m deeply honored and humbled to say the least,” said Brearley. “It doesn’t happen to too many people.” Brearleyite is an extremely rare, fine-grained mineral that is a new meteoritic Ca-Al (calcium-aluminum) and Cl-rich phase. The sample was discovered in a carbonaceous chondrite meteorite found in Northwest Africa in 2003. It likely formed from a reaction of krotite with hot Cl-bearing gases or fluids on a small asteroid, 4.56 billion years ago. Krotite is another recently discovered mineral that is named after Dr. Alexandre Krot, a colleague and collaborator of Brearley’s at the University of Hawai’i, Manoa. The mineral and its name, “brearleyite,” have been approved by the Commission on New Minerals, Nomenclature and Classification (CNMNC) of the International Mineralogical Association. Three round, thin sections of one inch diameter contain the material. source: http://news.unm.edu/2011/08/newly-discovered-mineral-in-meteorite-named-after-unm-professor/ (29th August 2011) paper: http://www.minsocam.org/msa/ammin/toc/Abstracts/2011_Abstracts/AS11_Abstracts/Ma_p1199_11.pdf Best wishes to you all Martin __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] more on Chinese impact petroglyph
Hi all - I received this message. Apparently Robert is having trouble posting to the list. Dirk, can you help him fix this? Hello Ed, I tried to post additional info on the ancient Chinese impact to meteorite-list but failed as usual. I'll have to tweak my settings a bit more. Anyway, you may be interested in further info below. http://www.sott.net/articles/show/234135-Falling-Meteor-Depicted-in-5000-Year-Old-Rock-Carving-in-North-China (originally from Xinhua.net) Hohho -- A 5,000-year old rock carving in north China's Inner Mongolia Autonomous Region depicts a falling meteor, said archaeologists on Saturday. A rock on the side of Dahei Mountain 大黑山 in the city of Chifeng 赤峰市( 42°15'28.14N, 118°53'12.68E), also known as Ulanhad, about 350 kl NE of Beijing, has images of people, domed houses and a fire ball with a long tail falling from the sky engraved on it, said Wu Jiacai, head of the Inner Mongolia rock paintings protection association. I believe it shows prehistoric people returning at dusk from a hunting trip to their domed houses, as a meteor falls from the sky, Wu shared his findings at the 6th Hongshan Cultural Forum that runs from August 25 to 27. He added that in the same location several years ago, another set of carvings were found showing people fleeing, snakes slithering and birds flying away, which might be what happened after the meteor hit the earth. -- Wu Jiacai has been quite active in that area. He previously found a carving of the Big Dipper. http://hua.umf.maine.edu/China/astronomy/tianpage/0002H_observe6724w.html In 2006, Xinhua News reported a find made by Wu Jiacai in Inner Mongolia. During an expedition to Baimiaozi Mountain near Chifeng City in the northwest, a stone, 310 centimeters long, was found on which had been carved 19 stars. The shape of the Big Dipper or Plough was on the north side of the stone. The stars are round indentations in the rock, as if someone had used a blunt instrument and ground out the shapes. The carving style is consistent with the Neolithic cultures. The shape of the Dipper is consistent with estimates of the star positions about 10,000 years ago. The carvings were found in the area where many artifacts from the Hongshan Culture dating to about 4000 BC have been found. Paintings on nearby rocks may date to the same period, but they have not been verified. They depict sun images as well as horses. The link below takes you to the original article in Chinese.

[meteorite-list] A Plan To Place An Asteroid In Earth Orbit
http://www.technologyreview.com/blog/arxiv/27112/ A Plan To Place An Asteroid In Earth Orbit Chinese scientists have discovered a near Earth asteroid that, with a slight push, could enter Earth orbit Technology Review (MIT) August 29, 2011 Most of the discussion about near Earth asteroids focuses on whether they represent a threat to Earth and what to do take if they turn out to be heading our way. But today, Hexi Baoyin and pals at Tsinghua University in Beijing offer a different take. The question they ask is how to place an asteroid in orbit around the Earth. Their conclusion is a little surprising. They say it's relatively straightforward to nudge a small asteroid in our direction. They've even discovered a number of candidates nearby that we might want to bring as little closer. Their inspiration is a phenomenon that astronomers have noticed with Jupiter. Every now and again, the gas giant captures a nearby object, which hangs around for a few years and then wanders off into space. A good example is the comet Oterma which went into orbit about Jupiter in1936 before heading off into the Solar System two years later. Could a similar thing happen to Earth, ask Baoyin and co. Having studied the orbits of the 6000 known near Earth objects (NEO), they say the short answer is no. None of them will come close enough for Earth to capture. However, a few of these objects will come maddeningly close. So near, in fact, that a small nudge would send them into Earth orbit. When such an NEO approaches Earth, it is possible to change its orbit energy...to make the NEO become a small satellite of the Earth, they say. A particularly good candidate is a 10-meter object called 2008EA9 which will pass within a million kilometres or so of Earth in 2049. 2008EA9 has a very similar orbital velocity as Earth's. Baoyin and co calculate that it could be fired into Earth orbit by changing its velocity by 410 metres per second. That's tiny. This nudge should place the asteroid in an orbit at about twice the distance of the Moon. From there it can be studied and mined, they say. Just like Oterma's, this orbit is likely to be temporary so 2008EA9 will probably wander off into the heavens after a few years. Interesting idea. What could possibly go wrong?

Hi, Bernd, List, A mere 10-meter spherical asteroid? (To a physicist, everything is spherical at the first approximation...) That's 523.6 cu. meters. At a rock density of 2 to 3 metric tons per cu. meter, that's somewhere between 1047.2 and 1570.8 metric tons. As a disaster, it's on a par with dropping a grand piano on a cartoon coyote. It would be a slow approach and MIGHT drop 10 kilos of meteorites, but probably not unless it grazed the atmosphere at the correct angle. However, a 10-meter asteroid is a tiny playground. What if it were a 100-meter asteroid, ten times bigger, and lots of surface (and about 1,000,000 tons). If you accidentally dropped that object on the Earth, you'd have a 250-meter crater and 0.2 MegaTon blast. Too big to play with. A 33-meter asteroid? Airbursts at 14 kilometers and splatters a lot of fast fragments, but no craters. From this I conclude that the 10-meter asteroid grab is a Modest Proposal. Unless, of course, it's an iron...

Re: [meteorite-list] A Plan To Place An Asteroid In Earth Orbit
Hello Sterling, Well, since the purpose of this is to mine an asteroid, it seems pretty foolish to waste all that effort on a 10 meter rock which you won't allow to be an iron. IT HAS TO BE AN IRON unless you want to waste money. Or do you want to mine antimony (element = Sb). That would be very successfully at mining Antimoney (element = $$$ouch$$$) !!! The problem is that most of the trace elements worth mining are siderophiles. So if you are going to mine silaceous, or most stony meteorites, I'd suggest going to a beach on earth (with a K-T outcropping if you insist ;-) with a tonka dump truck as the initial probe... Even at the 1 ppm level (a gross exaggeration for a stony meteorite), there is 1,200 grams of gold in your 1,200 ton 10 meter diameter spherical asteroid. Now I know gold is getting expensive, but let's keep our feet on terra firma. If you are going to mine anything, it needs to be worth it. Considering that mining such a small body is an expensive proposition (how do you think it would be smelted in orbit), they'd be better off just bringing back the 1,200 grams of raw asteroid and selling it to scientists and collectors. So, no matter how you cut up this pie in the sky in a spreadsheet, it ain't workin' Kindest wishes Doug -Original Message- From: Sterling K. Webb sterling_k_w...@sbcglobal.net To: Bernd V.

At a rock density of 2 to 3 metric tons per cu. meter, that's somewhere between 1047.2 and 1570.8 metric tons. As a disaster, it's on a par with dropping a grand piano on a cartoon coyote. It would be a slow approach and MIGHT drop 10 kilos of meteorites, but probably not unless it grazed the atmosphere at the correct angle. However, a 10-meter asteroid is a tiny playground. What if it were a 100-meter asteroid, ten times bigger, and lots of surface (and about 1,000,000 tons). If you accidentally dropped that object on the Earth, you'd have a 250-meter crater and 0.2 MegaTon blast. Too big to play with. A 33-meter asteroid? Airbursts at 14 kilometers and splatters a lot of fast fragments, but no craters. From this I conclude that the 10-meter asteroid grab is a Modest Proposal. Unless, of course, it's an iron...

Re: [meteorite-list] A Plan To Place An Asteroid In Earth Orbit
Doug, List, I'll refer you to the book, Mining The Sky, by John S. Lewis, which makes a nice solid 260-page case for the economic value of the asteroids. Or to Harrison Schmidt's economic analysis of the value of mining the lunar surface for REE's (Rare Earth Elements). Iron is worth about $0.25 per kilo, but nickel is now over $12 per kilo, Lanthanum oxide $134 per kilo, Neodymium $260 per kilo, and so forth. Or maybe, just check this source: http://en.wikipedia.org/wiki/Asteroid_mining At 1997 prices, a relatively small metallic asteroid with a diameter of 1.6 km (1 mile) contains more than 20 trillion US dollars worth of industrial and precious metals. At today's prices? A lot more. The not an iron comment was in relation to safety only. A 10-20-meter rock is safe to drop; an iron that size is not. Personally, I think the worry about accuracy of orbital maneuvers is silly and mis-placed. Few human operations are are so precise. Think about matchng up with Vesta from hundreds of millions of km away! The usual standard of accuracy is roughly akin to shooting the eye out of a one-eyed Jack at 100 miles away. Routine.

Think about matching up with Vesta from hundreds of millions of km away! I can see it now: China say they are practicing mining and everyone thinks, 'ok, the Moon is 50 years old', Venus and Mars have been done, let them have their thing and waste their money on that foolish endeavor '. While they put an orbiting Damocles sword around the Earth which, if they choose, can make that crater, if they succeed as you believe, right on top of the White House or Kremlin, and no heat seeking defensive missle is gong to change that. A false sense of confidence by the guys pushing the buttons is all we need by systems governed by Finagle's Law. I think we have too many weapons' risks in the world and am completely unimpressed by the idea of going all out to get another Moon, no matter how small, given the 'silly' risk considering who will be controlling its orbit. Comparing asteroids of unknown composition, rotational, vibrational and translational energy, and variable tensile strength and mass which need to be determined in-situ on the fly and and space vehicles carefully assembled on Earth is apples and oranges - make that pygmy cherries and gibberellically modified Edmund Scientific pomelos I dreamed of as a kid. There is a vast amount of energy required for most of these asteroid maneuvers, and a great deal of uncertainty to deal with in a hostile environment for construction. It is not easy. Now, why rock the boat at all. Just hook up some thrusters to the ISS which will be about as visitable the way things are headed (or send a separate mission) and have it hook up with an asteroid like 2006 RH120 (A temporary moon of Earth at times). If these NEO's are so close, no sense fighting the steering wheel. Just go with the flow and do your business, the world is already full of # drivers.
