Carl E. Did you ever get a response to your question on whether aubrites could possibly come from the Earth? Very interesting thoughts, to be sure, but I believe Sterling inferred that as a possibility. I also believe his last sentence says it all, I guess. As a side note, if aubrites did come from the Earth, What is the probability or possibility that they would contain some fossils? Microbes, sea shells, plant life...? Even water? If no fossils would that be compelling enough that they did not come from Earth? Carl Carl E wrote: Sterling, This may not surprise you but, I did not know that aubrites plotted on the same oxygen slope line as Earth and our Moon. Does this mean that Aubrites could possibly be meteorites from Earth? I believe it was decided earlier they would be called terranemeteorites?...

[meteorite-list] Cassini Reveals New Ring Quirks, Shadows During Saturn Equinox
Sept. 21, 2009 Dwayne C. Brown Headquarters, Washington 202-358-1726 dwayne.c.br...@nasa.gov Jia-Rui C. Cook Jet Propulsion Laboratory, Pasadena, Calif. 818-354-0850 jia-rui.c.c...@jpl.nasa.gov RELEASE: 09-217 CASSINI REVEALS NEW RING QUIRKS, SHADOWS DURING SATURN EQUINOX PASADENA, Calif. -- NASA scientists are marveling over the extent of ruffles and dust clouds revealed in the rings of Saturn during the planet's equinox last month. Scientists once thought the rings were almost completely flat, but new images reveal the heights of some newly discovered bumps in the rings are as high as the Rocky Mountains. NASA released the images Monday. It's like putting on 3-D glasses and seeing the third dimension for the first time, said Bob Pappalardo, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. This is among the most important events Cassini has shown us. On Aug. 11, sunlight hit Saturn's rings exactly edge-on, performing a celestial magic trick that made them all but disappear. The spectacle occurs twice during each orbit Saturn makes around the sun, which takes approximately 10,759 Earth days, or about 29.7 Earth years. Earth experiences a similar equinox phenomenon twice a year; the autumnal equinox will occur Sept. 22, when the sun will shine directly over Earth's equator. For about a week, scientists used the Cassini orbiter to look at puffy parts of Saturn's rings caught in white glare from the low-angle lighting. Scientists have known about vertical clumps sticking out of the rings in a handful of places, but they could not directly measure the height and breadth of the undulations and ridges until Saturn's equinox revealed their shadows. The biggest surprise was to see so many places of vertical relief above and below the otherwise paper-thin rings, said Linda Spilker, deputy project scientist at JPL. To understand what we are seeing will take more time, but the images and data will help develop a more complete understanding of how old the rings might be and how they are evolving. The chunks of ice that make up the main rings spread out 85,000 miles from the center of Saturn, but they had been thought to be only around 30 feet thick in the main rings, known as A, B, C, and D. In the new images, particles seemed to pile up in vertical formations in each of the rings. Rippling corrugations -- previously seen by Cassini to extend approximately 500 miles in the innermost D ring -- appear to undulate out to a total of 11,000 miles through the neighboring C ring to the B ring. The heights of some of the newly discovered bumps are comparable to the elevations of the Rocky Mountains. One ridge of icy ring particles, whipped up by the gravitational pull of Saturn's moon Daphnis as it travels through the plane of the rings, looms as high as 2.5 miles. It is the tallest vertical wall seen within the rings. We thought the plane of the rings was no taller than two stories of a modern-day building and instead we've come across walls more than two miles high, said Carolyn Porco, Cassini imaging team leader at the Space Science Institute in Boulder, Colo. Isn't that the most outrageous thing you could imagine? It truly is like something out of science fiction. Scientists also were intrigued by bright streaks in two different rings that appear to be clouds of dust kicked up in collisions between small space debris and ring particles. Understanding the rate and locations of impacts will help build better models of contamination and erosion in the rings and refine estimates of their age. The collision clouds were easier to see under the low-lighting conditions of equinox than under normal lighting conditions. At the same time Cassini was snapping visible-light photographs of Saturn's rings, the Composite Infrared Spectrometer instrument was taking the rings' temperatures. During equinox, the rings cooled to the lowest temperature ever recorded. The A ring dropped down to a frosty 382 degrees below zero Fahrenheit. Studying ring temperatures at equinox will help scientists better understand the sizes and other characteristics of the ring particles. The Cassini spacecraft has been observing Saturn, its moons and rings since it entered the planet's orbit in 2004. The spacecraft's instruments have discovered new rings and moons and have improved our understanding of Saturn's ring system. The Cassini-Huygens mission is a cooperative project of NASA and the European and Italian Space Agencies. JPL manages the mission for the Science Mission Directorate at NASA Headquarters in Washington. JPL also designed, developed and assembled the Cassini orbiter and its two onboard cameras. The imaging team is based at the Space Science Institute. The Composite Infrared Spectrometer team is based at NASA's Goddard Space Flight Center in Greenbelt, Md.

Re: [meteorite-list] What is and isn't a Widmanstatten Pattern was Cooling rates
I'd like to correct what I said two weeks back about alloys. I've talked with a specialist (Joe Goldstein) and he clarified the terminology for me as material scientists would use it. An alloy refers to a batch of metal containing more than one element (only one of which needs to be a metallic element). The term carries no implications about how the mixture formed or what its structure is. The term alloy should not be used to refer to a specific phase that crystallizes from an alloy or is present in the alloy. Taenite and kamacite are not alloys. They are phases (minerals). Therefore, hundreds of websites (including some professional ones) use the term incorrectly. An iron meteorite IS an alloy, even if it only contains one phase like taenite. Alloys can and often are composed of crystalline phases. Jeff Mr EMan wrote: --- On Mon, 9/7/09, Jeff Grossman jgross...@usgs.gov wrote: Most of the metallic minerals in iron meteorites are described as alloys in that they are composed of various metals combined together. I understood the distinction was that the Fe Ni formed a chemical compound not merely a mixture like copper and tin to make brass but even brass can form crystalline plates so that may be a bad example. It was my understanding that were it not for the mineral structure The Fe-Ni would be called an alloy. Agreed that it is frequently discussed in terms of alloy. It does not happen as the metal cools from the liquid state and solidifies. I stand corrected, 30 years is a lot of facts to keep in just one's head. I did recall correctly that there is a temperature range and below which all translocation stops. Seems off the top of my head it is 800°C. Goldstein and coworkers have shown that the process is controlled by the Fe-Ni-P phase diagram. I have long suspected that phosphorus was a key component in the process--likely as a catalyst. The Schreibersite seems to exist largely at the boundaries in thin laminae even surrounding trolite nodules. I look forward to reading Goldstein's paper. Thanks again, Elton -- Dr. Jeffrey N.

Re: [meteorite-list] What is and isn't a Widmanstatten Pattern was Cooling rates
I think there are some misconceptions here, although this is not my specialty. Most of the metallic minerals in iron meteorites are described as alloys in that they are composed of various metals combined together. These alloys have specific structures, e.g., the metal atoms in kamacite are arranged in a body-centered cubic structure and those in taenite are face-centered cubic. The minerals Kamacite and taenite are solid solutions of mainly Fe and Ni which can have a range of compositions without altering the basic structure. Tetrataenite is another alloy, but this time with a fixed composition (FeNi) and an ordered structure. Formation of the Widmanstatten structure is pretty well understood. It does not happen as the metal cools from the liquid state and solidifies. That process leads to the formation of just taenite. Only when the alloy cools to much lower temperature, after it is completely solid, can the Widmanstatten pattern form. High pressures are not involved. Goldstein and coworkers have shown that the process is controlled by the Fe-Ni-P phase diagram. Depending on the exact composition of the alloy, a variety of phase transformations take place over a range of temperatures, ultimately leading to the formation of kamacite and taenite. Composition and cooling rate play roles in determining in the structures we now observe. You can read about it in: http://articles.adsabs.harvard.edu/full/2005M%26PS...40..239Y jeff Mr EMan wrote: We had a metallurgist on the list a few years back that insisted Widmanstatten patterns were found everywhere and posted some micrographs supporting his assertion. As I recall he got very ill with us when we pointed out why, what he had photos of, weren't Widmanstatten patterns. It was focused on a physical casual similarity not causal chemistry. Once again Widmanstatten patterns aren't stress fractures nor alloy specific patterns. I further assert that metal in meteorites is NOT an alloy in that the nickel is in a specific locus within a molecule. It is therefore not a mixture but a compound, chemically speaking. Widmanstatten patterns are a cross-sectional view of crystal latices that result from the migration of nickel atoms over eons into two distinct unusual, zoned, crystalline arrangements. Bandwidth is actually plate thickness. The migration is chemically driven while the metal is molten and only occurs in a specific range of temperatures. This is a subtle but distinct difference. This migration may even be a molecule by molecule transfer of nickel atoms which takes millions of years to clear out a 3mm band. This is to say a nickel atom may move in one side of a molecule and forces the central nickel atom to the face and lacking stability is ejected out the other side--maybe not, as the actual displacement/sorting is still an enigma. The nickel iron content may assemble from a single form as it accretes and represent a move to homogeneity interupted when the mass ran out of thermal energy. It may all start out as taenite and part of it converts to kamacite or vice versa. Who really knows? I fully believe collisions would impede if not stop the process-- not speed it up. It is easy and natural to try to infer a similar pattern might be from a similar process but the only similarity is in low contrast photographs when the scale is ignored.

Hi Sterling - Oh Joy! - more junk which needs to be watched out for, which NASA will continue to ignore. While the explosive scaling laws are tough and rough, and I've had a stroke, my best current guess is that cometissimals are around 30 m diameter or so, based on the Rio Curaaca and Rupunini impacts. (Tunguska would be 2 cometissimals accreted.) With age the cometissimals further accrete/condense, depending on the time of their first agregation, which times appear to have a considerable spread. Another fragmentation mechanism besides solar energy may be nearby supernova radiation, which perhaps also provide injection energy. Maybe, appears, possibly, but certainly no one gets any money from NASA to work it out. Would someone fire Weiler now? E.P. Grondine Man and Impact in the Americas --- On Wed, 9/16/09, Sterling K.

A team of researchers began observing the comet 17P/Holmes in October 2007, after it was reported that the object, about 2.2 miles wide (3.6 km wide), had brightened by a million times in less than a day. UCLA researcher Rachel Stevenson and colleagues noted multiple fragments flying rapidly away from the comet's nucleus. They continued observing for several weeks after the outburst using the Canada-France-Hawaii Telescope in Hawaii and watched as the dust cloud ejected by the comet grew to be larger than the sun. The astronomers examined a sequence of images taken over nine nights using a digital filter that enhances small features. They found numerous tiny objects that moved away from the nucleus at speeds of up to 280 mph (125 meters per second). These objects were too bright to simply be bare rocks, but instead were more like mini comets, creating their own dust clouds as ice on their surfaces sublimated directly to vapor. Initially we thought this comet was unique simply because of the scale of the outburst, Stevenson said. But we soon realized that the aftermath of the outburst showed unusual features, such as these fast-moving fragments, that have not been detected around other comets. Although the outburst was impressive in the telescope images, it wasn't visible to the naked eye. Scientists aren't sure of the exact cause of the outburst. Possibly, pressure inside the comet built up as it moved closer to the sun, until eventually part of the surface broke away, releasing a huge cloud of dust and gas, as well as larger fragments. Even after ejecting mini comets, the solid nucleus of comet Holmes survived and continued on its orbit, seemingly unperturbed. Holmes takes about 6 years to circle the sun, and travels between the inner edge of the asteroid belt to beyond Jupiter. The comet is now moving away from the sun but will return to its closest approach in 2014, when astronomers will examine it for signs of further outbursts. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Idle speculation on panspermia
I agree, at least in part. Panspermia may not be the motivation to explore Europa and in truth, a decent sub-surface examination of that world will require a far greater commitment than $4Bn. The NEO programme needs a far greater commitment, as does any programme to counter such a threat that an NEO amy pose. I suppose it's all a question of budget. I am angry at the money put in to shoring up the banks that have put our economy on the verge of collapse, particularly since they seem unrepentant and want to use the money we have gifted them to return to earning more of the fat earnings they got before the collapse. The thought that the Constellation programme risks being shelved because of the recent problems is abhorent. And in the UK we look at a terrible situation for much of our future at the mercy of commerce. As a child, I'd hoped that mankind would begin colonising the Solar System. Thanks to recent events, I look like having ALL my dreams for the future of humanity crushed. Not just for my lifetime but for the 2-3 generations to follow me. All because of the greed of a handful of people who don't realise that a single rock from space could wipe out everything they or their progeny could have.

Pictures of the specimen can be seen here: http://www.mhmeteorites.com/images/millbillillie_86.jpg Thanks for your time.

Hello Richard; If you continue to do business with Eric Twelker you will find that he is as honest and reliable as you stated in your post and very much more.My experience over many years has shown me that and i highly respect him too. We have many such dealers in our community an i like you really appreciate their honesty and integrity.Good luck in your collecting and searching for the ellusive stone if you persue such stones in the fields.

Grondine epgrond...@yahoo.com; meteorite-list@meteoritecentral.com Subject: Re: [meteorite-list] Idle speculation on panspermia I agree, at least in part. Panspermia may not be the motivation to explore Europa and in truth, a decent sub-surface examination of that world will require a far greater commitment than $4Bn. The NEO programme needs a far greater commitment, as does any programme to counter such a threat that an NEO amy pose. I suppose it's all a question of budget. I am angry at the money put in to shoring up the banks that have put our economy on the verge of collapse, particularly since they seem unrepentant and want to use the money we have gifted them to return to earning more of the fat earnings they got before the collapse. The thought that the Constellation programme risks being shelved because of the recent problems is abhorent. And in the UK we look at a terrible situation for much of our future at the mercy of commerce. As a child, I'd hoped that mankind would begin colonising the Solar System. Thanks to recent events, I look like having ALL my dreams for the future of humanity crushed. Not just for my lifetime but for the 2-3 generations to follow me. All because of the greed of a handful of people who don't realise that a single rock from space could wipe out everything they or their progeny could have. And we seem powerless to do anything about it. In 100Ma, some species will be wondering how we managed to end up extinct. Rob McC --- On Tue, 9/22/09, E.P.

He was patient, understanding, communicative and ultimately I got it right and got my samples in first rate condition. He's helped me in other ways too regarding our passion since then, too. If I ever make it to Alaska, I'd love to meet up with him and buy him a drink. He's a top bloke and while we're in the good-will mode, I'd like to thank him for everything he's done for me and my attempts to forward meteorites to kids in Scotland.

Re: [meteorite-list] Shivalingams impactites?
True. Quartz is a mineral, and can be deposited in any number of ways. In this case, based on gross physical appearance, I'd say the shiva lingams are likely made of a type of jasper, but I'm not qualified to tell. Given the fact that they're definitely more coarse-grained than other varieties like chalcedony and agate, I'm not even sure 'cryptocrystalline is the correct way to describe them - perhaps someone else who has a background in geology/mineralogy and is familiar with shiva lingams can comment here. The layering that can be seen in them is reminiscent of banded claystones; that's why I said sedimentary, but I could well be wrong.

I most definitely agree 100%. Erik Twelker helped me a while back to pick out/buy a very special meteorite (to me) and was THE definition of first class service. Still have the meteorite to this day.
