Re: [meteorite-list] Possible Meteorite Value if used as Tools
Martin Horejsi coined the term Tool box meteorite. I think he wrote an article on the idea and there were many more uses than I would of thought of. He had a huge slice of a meteorite that was used as a wheel chock to keep a wagon or cart from moving on a hill. I use a big NWA to set my hat on but we decided that does not count unless it was a natural uses of the stone prior to knowing it was special. Uses after it is a known meteorite are just a novelty and do not make the stone a tool box meteorite. Tom In a message dated 3/2/2010 9:52:07 A.M.

Re: [meteorite-list] Science page update / desert varnish on meteorites
Yes there is microscopic beauty even in desert varnish. I love to examine the stuff in incident cross polarized light. Email me for some eye popping 700X images. The minerals that make up the varnish have different reflective properties which allow for almost irridized looking effects when the polarization is played with. I am just a layman but my observations (for what they are worth) is that the varnish growth depends not only on the terrestrial environment but the stone make up as well. Migrating minerals from within the meteorite feed the surface. I also have noticed small pieces of the meteorite broken off and grown into the varnish as well as sand grains captured and encased in the varnish. Occasionally I have seen meteorites that look jeweled or completely encrusted in quartz sand grains. Tom In a message dated 3/1/2010 3:23:24 P.M.

Re: [meteorite-list] Microscope search
Hi Paul, I love to talk about microscopes. In fact I just bought an other one today. In May of 2008 I did a little write up for Meteorite Times titled The right microscope for you It does not go into which brand is better than others or the like but rather, what type of microscope should you be looking for. It sounds like you will be best served by a stereo scope and you are in luck. Those are plentifully on eBay in all price ranges and as a result of the frequent examples ending every day, I see some killer deals. Check out my article. It has micrographs using different type of scopes so you can se what you would like to accomplish. http://www.meteorite-times.com/Back_Links/2008/may/index.htm This link should take you right to the article.

Re: [meteorite-list] Microscope search
Hi list, Richard is absolutely right when he said. so a simple $100 stereo microscope might be enough to get your feet wet and help solidify the direction you want to go if, I mean when you purchase your next microscope! He touches on an aspect that meteorite and microscope enthusiasts have known since our first scope. It is more interesting close up. Any specimen in your collection is much more interesting when you can observe the subtleties that make it different from the rest. If you care to look at the micrographs of Angrites in my gallery you will know what I am saying. I might also add. I have inexpensive some Xpol scopes that are beautiful to look at thin sections in. I don't take micrographs with these scopes but for observation they are wonderful and even with the setup I use to take micrographs on, the view first hand is 10X better than a picture. I would even say that the observational view in one of these inexpensive scopes is better than the best micrograph I can produce. Tom In a message dated 2/19/2010 7:40:05 P.M. Mountain Standard Time, damoc...@yahoo.com writes: Hey Paul. A seemingly simple question with literally hundreds of answers. I just purchased a microscope, but I think my needs were possibly very different than many of the people on this list. Here's a few questions to ask yourself before you can narrow down the microscope that is right for you. How much can you budget for the microscope? Do you only want to view individuals and slices at lower power to see the details you mention better, or do you want to view thin sections in polarized light at high magnification? Do you want to do photography of your meteorites? Do you want to view things other than meteorites, ie. biological specimens? If you simply want to view your specimens magnified and have no plans to view or photograph thin sections, you can find a reasonably good 10x - 30x stereo microscope for about $100. For another $50 you can find a VGA webcam that can be mounted where one of the eyepieces goes and view your specimens on your computer screen. Of course if you want to have a microscope that can do everything you're going to have to have a very large budget. But, as you can see on Tom's page, he has multiple microscopes to do what he needs, so a simple $100 stereo microscope might be enough to get your feet wet and help solidify the direction you want to go if, I mean when you purchase your next microscope!

[meteorite-list] Martin Cubes Antiqued wood scale cubes Ad
Hi list, As I have mentioned to the list previously, I have stared making wood scale/orientation cubes. There are a couple versions of these things. One is the new cube with a simple oil finish. The other is an old wood finished with several layers of toasted and striped Danish Oil and varnish then tumbled in a brass tumbler (No grit) just long enough to wear edges. I have a habit of coming up with names for things like Perfect Chondrule or Ugly Black Stuff and a name has emerged for these antique style cubes. I thought some of you might like the story. After making some simple wood cubes I showed pictures to Jeff Kuyken and it was his idea that these would be good for use with historic meteorites. Well, historic meteorites naturally made me think of Martin Horejsi. In fact for most of us, when historic meteorites are mentioned we think of Martin! He is an expert in historic meteorites and has been witting articles on them in Meteorite Magazine and Meteorite Times for years. We also are friends. We have cut and polished more than a few of his treasures while talking about rocks. His knowledge is amazing and what's better he has interesting stories about nearly all of their histories. He wrote a From the Strewnfields article about one of those days in the August 2006 issue of Meteorite Magazine. I have mentioned before how meticulous Martin is. His style is total precision while mine is quick. It was hilarious to watch us get ready to cut one of his rare historic stones. I think my grab and cut approach drove him mad. He once muttered something to the effect of That might be OK for an sun scorched NWA but not this rock Anyway, I tried to create some thing cool. I wanted to come up with a cube that even Martin would put next to his Ensisheim. As I worked on them, such as when I went on one of my frequent trips down to the work shop to check on the batch in the toaster oven or some other thing, I told my wife I'm going down to check on the Martin cubes That name has stuck and they are now known as Martin Cubes. They were a pain to make so I am not sure if I will produce an other batch. If I hear Martin has placed one in his showcase next to his Ensisheim slice, I will know I did a good job! I have ordinary wood cubes I am including with my eBay sales such as this one. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=260550364645ssPageName=S TRK:MESELX:IT These are clean and fresh, made of new pine.

Re: [meteorite-list] Meteorite Yields Carbon Crystals Harder Than Diamond
Hi list, This is off topic (sort of) to this very interesting post but it does mention graphite and diamonds. I have shared this observation before and every time I have mentioned it I have been taken wrong! Has any else noticed how the graphite inclusions in the fossil EL3, NWA 2828, 2965, Al Haggounia 001 etc. fool an electronic diamond tester? Now this is the part I have been taken wrong on, I'm not saying I have found testable size diamonds but rather the graphite will set off an electronic diamond tester! Those testers operate on thermal conductivity. I can take my optical scopes to 2000X but that is no help in this stuff. I have tried similar inclusions in other meteorites and nothing. Is the inclusion made of nano diamonds or just a material that is as thermally conductive as diamonds? Which ever, it is interesting! Tom Phillips In a message dated 2/3/2010 6:23:57 P.M. Mountain Standard Time, baalke @zagami.jpl.nasa.gov writes: http://www.physorg.com/news184402061.html Meteorite yields carbon crystals harder than diamond by Lin Edwards physorg.com February 3, 2010 (PhysOrg.com) -- Two new types of ultra-hard carbon crystals have been found by researchers investigating the ureilite class Haverö meteorite that crashed to Earth in Finland in 1971. Ureilite meteorites are carbon-rich and known to contain graphite and diamonds. The super-hard diamonds were created when graphite in the meteorite experienced the intense heat and pressure of entering the Earth's atmosphere and crashing into the ground. The graphite layers would have been heated and shocked enough to create bonds between them, in much the same way as humans manufacture diamonds. The new carbon crystals were too small to test for precise hardness but they are known to be harder than normal diamonds because the researchers found them by using a diamond paste to polish a slice of the meteorite. The crystals were raised more than 10 µm above the polished surface, which meant they were harder than the diamonds in the polishing paste. The researchers had seen carbon crystals that resisted the diamond polishing in one direction before, but the new crystals were unaffected when polished in every direction. The scientists then used an array of mineralogical instruments, including microscopy, spectroscopy and energy-dispersive X-rays among others, to study the structure of the crystals. This allowed them to identify them as representing two new carbon polymorphs or diamond polytypes. One is an ultra-hard rhombohedral carbon polymorph similar to diamond, while the other is a 21R diamond polytype ultra-hard diamond. The existence of ultra-hard diamonds had been predicted decades ago, but they have never before been found in nature. The novel form consists of fused graphite sheets similar to artificial diamond. Professor Tristan Ferroir, leader of the research team from the Université de Lyon in France, said the discovery was accidental, but they had thought an examination of the meteorite would lead to new findings on the carbon system. Professor Ferroir said there is currently no way to compare the structure of the new crystals to boron nitride and lonsdaleite, the artificially manufactured ultra-hard diamonds, but the findings help scientists gain a better understanding of carbon polymorphs and give them new materials to investigate and perhaps synthesize. They also show the carbon system is more complex than previously thought. The findings on the new diamond were published in the Earth and Planetary Science Letters journal on February 15.

[meteorite-list] Paper on chondrule formation and synthetic chondrules
Hi List, I thought some of you might enjoy this portion of a science paper on meteorite chondrules. It is part of a paper on microscopes posted in Molecular Expressions (An online microscope site) The first half of the paper is on microscopes so many of you will want to skip that part. Tom Phillips PHOTOMICROGRAPHY IN THE GEOLOGICAL SCIENCES Michael W. Davidson Institute of Molecular Biophysics Center for Materials Research and Technology (MARTECH) National High Magnetic Field Laboratory (NHMFL) Supercomputer Computations Research Institute (SCRI) Florida State University, Tallahassee, Florida 32306 Telephone: 850-644-0542 Fax: 850-644-8920 Gary E. Lofgren Planetary Materials Branch Solar System Exploration Division Code SN2 NASA Johnson Space Center Houston, Texas 77058 Telephone: 713-483-6187 Fax: 713-483-2696 The whole article is at http://micro.magnet.fsu.edu/publications/pages/journal.html Chondrules are small spheres (.1 to 10mm in diameter) which are the major constituent of chondritic meteorites. Chondrites are considered samples of primitive solar system materials. If we can understand how chondrules form, we will have an important clue to the early history of our solar system. Most chondrules have an igneous texture which forms by crystal growth (usually rapid) from a supercooled melt. Such textures are commonly described as porphyritic (large, equant crystals in a fine grained matrix), barred (dendrites comprised of parallel thin blades or plates), or radiating (sprays of fine fibers). The models proposed for formation of chondrules can be divided into two groups (McSween, 1977). In one group of models, chondrules form by melting and subsequent crystallization of preexisting, largely crystalline material from the solar nebula. The primary differences between these models are the kinds of materials which are melted and the nature of the sources of heat for the melting. In the other group of models, chondrules form by condensation of liquids from the solar nebula gas which then crystallize upon cooling. Variations between these models result from differences in the condensation sequence of the minerals and melts and the temperatures of nucleation. One means of testing models of chondrule formation is to determine the conditions necessary to duplicate these textures by experimentally crystallizing chondrule melts in the laboratory. Efforts to reproduce the textures of chondrules experimentally have been successful only when we began to understand the important role that heterogeneous nucleation plays in the development of igneous rock textures. Unless heterogeneous nuclei are present in the chondrule melt, porphyritic textures will not be produced. The dendritic or radiating textures will form instead. The treatment of heterogeneous nucleation follows the model developed by Turnbull (1950) to explain many of the characteristics of heterogeneous nucleation. This model was applied to heterogeneous nucleation in basaltic systems by Lofgren (1983). Simply stated, the model says that in any steady-state melt at a given temperature there is a characteristic distribution of embryos. The embryo is crystalline material which is smaller than the critical size necessary to be a stable nucleus and cause nucleation. It is a subcritical-sized potential heterogeneous nucleus. Embryos exist whether stable, supercritically-sized nuclei are present or not. If a melt is sufficiently superheated, embryos can be eliminated. Nucleation would then require a surface, presumably the container and the barrier to nucleation would be much higher than in the case where embryos were present. Qualitatively, such nucleation would resemble homogeneous nucleation; but, if a surface is available, the energy barrier would be much lower than for homogeneous nucleation. Glasses would form from chondrule melts most readily if they are superheated, thus destroying the embryos and increasing the barrier to nucleation. Lower melting temperatures would allow embryos to be retained. These can then grow upon cooling and become nuclei. Embryos also can become nuclei without changing size, because the size at which an embryo becomes a nucleus depends upon the degree of supercooling in the melt. Thus, an increase in the degree of supercooling can cause an embryo to become a nucleus and nucleation to occur. If relict crystals are present in the melt at the initiation of cooling, the more equilibrium-like crystals typical of porphyritic textures are formed. When such experiments are quenched, the final product contains glass or fine grained material, often dendritic, enclosing the equilibrium phenocrysts. An example of this texture produced in experiments is shown in Figure 7. Equant, well formed crystals of olivine are set in a glassy matrix with a few dendrites present. In the natural prophyritic
[meteorite-list] Weird Iron Sulfide Barred Chondrule Looking Feature
Hi List, I just ran onto an Iron Sulfide inclusion in an unclassified impact melt. It is structured like a barred chondrule. I have never seen any like it before. Has any one else seen this feature? I have some micrographs if any one wants to look just email me. I will post images to my Gallery but that will likely take some time and I am interested in your observations while I am still working on it.

I am proud to take reflected light images at magnifications up to 1600X as this is close to the limit of optical visible light microscopes. the details are lost at levels much higher because the wave lengths of visible light are to big.

[meteorite-list] A good read on converting standard microscopes to polarizing-chondrule formation
Hi list, Not a typo, one article that covers such things as conversion of a standard bright field microscope to polarization, various lighting techniques, as well as chondrule formation. A little slow in parts but then again, this isn't HBO! An example to persuade you to take a look or cause you to hit your delete key so fast it's left with fusion crust. The classic barred olivine texture is a single plate dendrite (Donaldson, 1976) which shares the entire chondrule with the remaining glass or subsequent crystallization products. Olivine rimming the chondrule is often in optical continuity with the dendrite and thus is part of the plate dendrite. Because this texture is so striking, barred olivine (BO) chondrules are well known even to people outside the field of meteorites. When chondrules are discussed, a photomicrograph of a barred olivine texture is usually chosen as one of a few or even the only example. It is not surprising that considerable effort has been expended understanding its origin. Barred olivine textures comprise only a few percent of melt-textured chondrules, usually less than 5% (Gooding and Keil, 1981). The classic barred texture represents only 10% of the type 3 ordinary chondrite BO chondrules. By careful study, Weisberg (1987) determined that the multiple plate dendrite is a much more common that the single dendrite. Most investigators propose that BO chondrules form from melt droplets that crystallize rapidly upon cooling. Enjoy? but then check out my Meteorite Micrograph Gallery hosted by Meteorite Times. I employ most of the techniques outlined in this article in my various image styles. http://www.meteorite.com/meteorite-gallery/meteorites-alpha_frame.htm Tom Phillips __ 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
Re: [meteorite-list] Refraction and cutting solvents
Hi Paul, I am not aware of any change to optical properties of material due to lubricants but with the more advanced testing watch out. I had some material that I polished with a diamond slurry to 1/4 micron. I sent some to a respected researcher that I occasionally consult (he helps me out a lot!). The sample was analyzed on a Raman Spectrometer and found to contain carbon. As this material was (kind of) unique and produced an odor when cutting or polishing, I naturally figured it was carbonaceous. I circulated that information and wound up quite embarrassed when it turned out to be an OC. It appears the diamond slurry was an oil base that changed the spectrometer signature. I think the proper solvent wash would of prevent this but I didn't think of it so I never washed the sample or told my friend what I had used in the sample preparation.

[meteorite-list] An offer for meteorite microimaging to dealers (No thin section required)
Hi list, For the last couple years I have been working nearly exclusively on thin sections in cross polarized light. This was due, only partly, to my failure to come up with a satisfactory digital photo adapter on my Neophot but most significantly to Jeff Hodges fantastic thin section library. He has very generously loaned me thin sections for years. I am now back on track with the Neophot (It is a large incident (reflected) light inverted microscope). In fact, I just purchased another one. It has on it some very special parts such as a polarized light illuminator with a sub parallel compensator, Bertrand lens and micro polarizing adjustments. I have looked for years for these parts. They had seemed to be made out of pure unobtaineum. For an example of the type of images I will be producing please look at my latest post to my micrograph gallery on JaH 073. Unlike cross polarized transmitted light thin section images, these images are true color. As I like to say Just what it looks like way up close. http://www.meteorite.com/meteorite-gallery/articles/jah_073/ Please keep in mind, I am not vested in my JaH 073 observations. They are just a guess. I am open to other interpretations of the images. It is mostly just me having fun with micrographs. I am looking for interesting classified material to image. (I have boxes of unclassified NWA so I don't need that kind of stuff) I do not need a thin section but a sample of roughly 1 gram or larger that I am free to polish. I finish with a 1/4 micron diamond slurry to get clear shots at magnifications up to 1600 X. I don't want to do any cutting. Things happen when cutting. Things like falling apart material and unaccounted for missing crumbs! I am just not set up for that. I will safely return the sample with a CD of images that you and I are free to use. You can use the images to promote your material, heck, you can make Tee shirts and calendars if you like. In fact, I want you to use them!!! All I ask is that my name is attached to all products or postings, and that I am free to use or pass along the images as well. The operative word is return, so I am looking for the GOOD STUFF. I am shooting at a resolution of 12 mp so they should be up to any application you might have in mind. Ideally, I would also like to partner in an article where I provide the images and you do the rest! Basically, you write an article and I will give you some additional images to add to the mix. Even if we produce an article and it is not placed you could use it in your promotion of the material for sale and I will post it to my gallery. Please email me with any ideas.

[meteorite-list] JaH 073 micrograph
Hi list, The email embed program for images leaves a lot to be desired. The images are coarse and with out detail but when I send a full size image, few get through to all of you that request them. The solution? I used PhotoShop to reduce the image from 4000 pixel wide to 1000. It will go through as an attachment and still be large enough to have the necessary detail. I know I promised many of you to just send the stupid pictures already but I tried using my address book to Send All and I had a huge list. Most recipients would not be interested in a JaH 073 vein. Anyway, The shot is at 700X of a vein in JaH 073. In incident light!!! My favorite JaH 073 stuff that I think to of been formed in the presence of water (Only by comparison to terrestrial rocks ((I don't have an SEM)) ). I have been working on a new Neophot adapter and this is getting just about where I like it. I have a ton more (and that's a lot considering they are digital) that I will post to my galley in a week or so. If you want a look, please email me! Also, I just ordered my centimeter cube from Jeff http://www.scalecubes.com/about.htmlIf you haven't ordered yours already then mine will be a lower number than yours! How will you sleep with that?

[meteorite-list] TC3 show and an observation
Hi List, I watched the National Geographic's Naked Science: Countdown to Impact which is the story of asteroid/meteorite TC3. What caught my attention was the diversity of material within the samples collected. After a few years of weathering, would all those stones even be thought to of come from the same fall? It got me wondering about the diversity in other meteorite material. Have others working with meteorites noticed large diversity in material type within a group of named samples. I'm not talking about a single stone (perhaps even brecciated) but rather a fall with a large number of recovered individuals. I am not an expert but I have cut, polished and examined mare than an average amount of meteorites and in those named materials where I have cut into more than 50 stones, most have such a large diversity I could send in a type sample that would support any thing from a type 3 to a 6. Some primary examples are SaU 001, JaH 055, JaH 073 and the provisional NWA 5142. These examples are only those where I have cut a large amount. There must be other more dramatic examples others have noticed. Aside from that question I had, it was a great informative and entertaining show. Well done! for info on the show see: http://channel.nationalgeographic.com/series/naked-science/4652/Overview Tom Phillips __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Barred Chondrule Fans JaH 055 incident light micrograph gallery update
Hi List, Last week I emailed the list about a SaU 001 chondrule shot that I wanted to send in full resolution to anyone who wanted it. There were over 40 takers but unfortunately many had Internet provider limits on file size so they couldn't get the full size file. I had some beautiful high resolution shots of this JaH 055 chondrule that you need to se to appreciate. They are not using a thin section and they are in true color. Really what they look like way up close. I wanted to send a full size file again but the last try didn't work out so well. Paul (Meteorite Times and Meteorite Exchange) helped out. He just set up a new set of JaH 055 barred chondrule reflected light images on my gallery and posted one full size in image of the month. You can down load it off the site with out dealing with email size limits! Both can be found in my gallery http://www.meteorite.com/meteorite-gallery/meteorites-feat_frame.htm Select Features on the top tab and the image of the month or barred chondrule. While you are there, I just put up a set of Al Huqf 007 taken in transmitted cross polarized light. These are the colorful thin section Xpol shots.

[meteorite-list] SaU 001 Incident Light Micrograph
Hi List, My first love in meteorite micrographs is high magnification incident light (reflected) images of thick samples. My first article in Meteorite Magazine was this technique. For the last couple years I have only worked on cross polarized transmitted light images of thin sections. One of the reasons is camera/adapter for my Neophot issues. I was given the use of a lathe and I turned down a suitable part to address this. I wanted to share a shot of a SaU 001 chondrule up close. If you would like to take a look please email me and let me know if you want the reduced embedded file or the full size 12mp as an attachment. (Many Internet hosts will reject that large of a file). I think the chondrule looks like a planet.

[meteorite-list] impactacite question.
Hi List, About a year ago I posted the list for some of you to view an interesting breccia I had found. Several people took a look at my photos and agreed the stuff was quite interesting but no conclusions were drawn. Does any one want to look at some pics and tell me if this material is a possible impactacite and, who I could send a sample to? A year ago I had found only two stones and no more. Since then the state has started a highway widening project fronting my land and they are moving a couple million cubic yards out of a hill side and spreading in on low spots (some on my land). This has opened up acres of pool table smooth fresh digs to look over. (While dodging the earth moving equipment!) I have found many more samples. I am wondering if it is worth the effort to look for more. About 14 thousand years ago Lake Bonneville drained through the valley here and deposited quite a variety of materials all the way from Utah. This breccia is found down low in the valley and I can not find any on the exposed canyon walls or up on the shelf. This leads me to think it was deposited in the Great Bonneville Wash Out. I know this sounds crazy, but have there been any theories of Lake Bonneville (The Great Salt Lake) having an impact origin??? Email me to view a few pics and share your opinion.

Hi Michael, I just might have you beat. I spend most of my meteorite time on the microscopes but I have spent more days hunting than I care to remember and nothing. My icing on the cake was when I took my son to Gold Basin and was certain he would find some thing. I bought a 156 gr. Gold Basin on eBay and placed it under a bush. We hunted around so as to not make it look obvious of what I had done and then we worked our way back to the hidden stone. Two hours of looking for it and it was lost.

I have only hunted at 7 sites in the last 4 years, spending 90% of my time at two sites. West was a fun 28 day detour in it all. Before 2005 I was an amateur meteorite hunter only hitting one or two places a year with metal detector in hand. In 2003 I picked up 113 meteorites from Park Forest, one being 11 km from the main mass, I found the most there, but I don't think anyone else was even trying to find a lot. For the most part, over the years I invested most of my time and made most of my money from being a dealer not a hunter. If we are judging this by total weight recovered, I am beat by quite a few people on lifetime numbers. If we are judged by total number recoveries from different locations, there are many people who beat me. If we judge by profit from meteorite sales of found meteorites, there are many more higher on that list than I am. Maybe, if you judged success by most media coverage (TV, newspaper, Radio, Magazines,internet, etc.) I would be at the top of that list. But I hardly think that is a good barometer for determining the Most Successful Meteorite Hunter. Success is our world is often judged by the amount of money you make. So who has made the most money? But what about people that are not in this for the bottom line only? Cottingham mentioned not willing to sacrifice family time to be gone from home too much. If his kids grow up emotionally well balanced because he was in their lives more, but someone else finds more meteorites but has a lousy home life, some people might argue who really was more of a success? It is easier to measure who did the best at one location. Let's all go to Holbrook for the weekend, and whomever finds the most in number wins the title for the day. Or drop us off at Munonionalusta for a week, and we can put the bounty on the scales 7 days later. Who found the biggest West? Or the most Wests? Or the most total weight of Wests? Who will find the most at this new Arizona Strewnfield? I think it might be possible to single out who might have had the best year financially, in total weight, in total numbers etc in a given year, but to stretch it out for more than a decade long period of time, that gets a bit tough, and very subjective. Someone might be better or worse than their numbers indicate because of other factors in their life. Others might just get a little lucky. It is all so subjective. And to top it off, I don't know if anyone out there is hell bent on finding the most new meteorites, or the most total recovered weight, or the biggest single meteorite of all time. Most of us do this because we love it. We love the challenge that each day brings, that each new

[meteorite-list] Circular polarizers and micrographs
Hi List, Many of you are not at all interested in meteorite micrographs but quite a few list members have contacted me over the years about various aspects of meteorite micrographs. Many list members are taking very high quality shots but have not shared them with the list yet. In my Meteorite Micrograph Gallery I primarily use three different microscopes. One of those scopes happened to be set up with a circular polarizer in the analyzer position. This setup worked well with my Nikon auto focus camera but I found I had better results with an older camera on my other scopes. I set out to figure it all out. Many of you are way ahead of me on this one but this could save a lot of trial and error for those who have not given it much thought yet. This is copied from an advertising site for Hoya filters. http://www.thkphoto.com/products/hoya/gf-04.html Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot. While we are not interested in white fluffy clouds, we are interested in clear sharp focus and linear polarizers detrimentally affect the focus when used with auto focus cameras. They can still work but you might need to take several shots to get one good one. I have found that you can use any polarizer in the first position (based on the light path) but the final filter (called the analyzer) is best if it is a circular polarizer. The auto focus is better and also fast and crisp so your camera doesn't sound like it is sawing logs trying to find focus. I just set up all my scopes with circular polarizers in the analyzer position. This was no easy task as none of the old aus Jena gear had a circular polarizer option (They were made prior to many auto focus cameras). I had to take larger sizes of filters to my rock saw and shape them into the correct size by holding them against the side of the blade and rotating them. If you attempt a change out you will like the results. You will also notice the circular polarizers are directional. That is they only work properly in one direction and not the other. And yes, camera filters are just as good as original equipment polarizers. I have a couple shots I would like to share as an example. They were taken with an auto focus Nikon, through the eyepiece using a circular polaryser analyzer. I will send them full size to any one who is interested. **We found the real ‘Hotel California’ and the ‘Seinfeld’ diner. What will you find? Explore WhereItsAt.com.

[meteorite-list] Solar meteorite
Since working on the NWA 5000 thin section over a year ago I have worked with quite a number of lunar slides. I have always been primarily interested in the glass. My most recent effort is NWA 4483 Lunar feldspathic granulitic imapactite. It has a lot of glass. It is nearly 85% isotropic glass, (rough estimate). Norbrt Classen and I plan on an up coming article for Meteorite Times on it. My point is none of the lunar glass I have examined has well defined solar wind vesicles like NWA 5000. When sharing micrographs or just talking meteorites, I am surprised at how few people are aware of this unique feature in NWA 5000. It's taken me looking at the lunar glass of many samples to give me an appreciation of just how cool NWA 5000 really is. It the closest thing to owning a Solar Meteorite. Real trapped solar wind in little bubbles!!! If you are interested in checking out the solar wind vesicle photos please go to Meteorite Times back issues and select august 2008, then go to Micro Visions in the menu on the left. http://www.meteorite-times.com/back_issues.htm I have no NWA 5000 material for sale so I am not promoting anything, just sharing a cool observation and wondering if there are any other Lunar meteorites with this same phenomenon.

Re: [meteorite-list] black diamonds from Canyon Diablo
Hi Laurence, Great paper! Thanks for sharing. I had a related observation that I thought you might be able to shed some light on. The EL3 Enstatite NWA 2965 (and a whole lot more names/numbers) has small graphite inclusions. I notice them most in the Blue Phase. I have found that these inclusions fool an electronic diamond tester. Other meteorite graphite does not (At least what I have tried). The grains are to small for me to resolve on my optical microscope, even at a magnification of 1800X. Is this likely just a fluke of the testing (Thermal conductivity), or are there likely to be micro diamonds in the material at a level sufficient to fool the tester? The inclusions are soft and can be easily gouged out with a metal tool. Thanks, Tom Phillips In a message dated 5/2/2009 3:53:06 P.M.

Re: [meteorite-list] ONE AD PER WEEK I have an idea!
I agree with Dean, the negative vibe on this list has been high. I can think of several people whom I respect in the meteorite world (some who work in teaching and or research) that will not use the list because of this atmosphere. Let's face it, the list is about communication of information on meteorites. That might be scientific information or sales information. Were all collectors so it's ALL GOOD! Abuse of advertising should be addressed by the list administrator ONLY! All sounding off from anyone about anything related to advertising does harm to the list and it's reputation (right now it has earned a very hostile reputation). My idea? Let's start a new thread on your favorite dealers. I'll start and I'll start with Dean Bessey. Dean was one of the first dealers to offer beautiful unclassified NWA's for (at the time) unheard of low prices. No where could you get large beautiful meteorites for the price he was asking. It is because of Dean I got hooked on meteorites. Over many years I have purchased over 200 Kg (no kidding) from him and have loved every one. Dean has launched many new meteorite collectors.

Re: [meteorite-list] West - Blue-Silvery Markings
Hi Robert and list, I just looked at the post of the image on Michael's site (Thanks!!!). http://www.rocksfromspace.org/West-markings.html SaU 001 has a copper metallic sheen on some of the examples. I wonder if it is the same process at work? I am convinced it is the result of metals internal to the meteorite vaporized and depositing in the crust. Very similar to pottery glazes. Different metals=different colors. This metallic glaze has stood up to hundreds of years in the Oman desert. I think it is in the glass of the crust (so to speak). I have taken some heat on this but I have tried to wear the glaze off by carrying small samples in my pocket for extended periods. It is in the glass that forms the crust and is not part of the weathering process as has been suggested in SaU 001. In fact this metalic finish has been dismissed as just a weathering phenomenon. I am very excited to see a similar looking deposit on a fresh fall. Email me for some cool SaU 001 crust shoots but be advised, I am not as good with macro as micro!

While others are just interesting. Some who suspect they have found a meteorite, have found a meteorite! An appeal to this kind of forum would likely produce some finds but it would be overwhelming to deal with. I'm not up to it!

Well said Elton! Thanks Tom In a message dated 2/8/2009 11:40:07 P.M. Mountain Standard Time, mstrema...@yahoo.com writes: Good Question: What about Olivine, would the melt point of Olivine be higher than the glass? Molten olivine at silica glass melting(akafusion)temperatures. Not at all as olivine has the highest fusion temperature in Bowen's Reaction Series(BRS). Thus it is the first to crystalize and precipitate out of magma. This is why it is used as a refactory material in making fire bricks. Olivine fuses at 1890*C, well above where iron fuses. The two minerals making up olivine: forsterite and fayalite are very close in fusion temperatures as to be negligible in general discussion. Silica, aka quartz has the lowest fusion temperature in BRS(1600*C +) and thusly rare in meteorites. That fact and this:When olivine is forced to react with quartz in any of several situations such as reheating,deep mantle pressures,extended cooling cycles,etc., the two minerals reform to produce enstatite. (Does the H and E chondrite composition and their parent bodies make more sense?) When this quality of olivine and it's implications sink in, one might experience the Eureka effect.

Greg Hupe had a 99 gr end slice of Zag that he had started a week earlier. I had bid several days before the end of the auction. When it ended on the evening of the 11th and I won the auction I sure wasn't thinking of meteorites and I don't think Greg was either. It seems like the whole world shifted on that day. Kind of like a Sliders episode. Any one remember that SiFi show? It sure doesn't feel like were back in the proper dimension yet.

Re: [meteorite-list] question for thin section collectors
Hi Leigh Anne, I'm answering on list so any one can correct me if I am not accurate in my assessment. First, a standard biological microscope slide is 1 X 3 or 25 mm X 75 mm. A standard petrographic slide is 25 mm X 45 mm. Quite a bit shorter! I have a large pile of petrographic slides (Meteorite thin sections) that I keep in those plastic cases Mike Tettenborn just posted about. I like the cases but I have often looked for a cool slide box fitted to the smaller petrographic slides. I have found many biological slide boxes. It would seem to me that the meteorite community would enjoy a quality petrographic slide box. Also, and this is just a personal observation, I would think that the collectors with a quantity of slides, worth hundreds and at times thousands each, would appreciate a beautiful work of art and not just an other box. I have found some vintage black bake light boxes in the smaller size but that is about as cool as I could come up with after a lot of searching. The great old wood Victorian Microscope slide boxes are almost entirely the larger size. Post the list if he makes any!!! Tom In a message dated 1/4/2009 4:30:53 P.M.

[meteorite-list] NWA 4901 write up request
Hi list, I was planning on using some killer micrographs of NWA 4901, the ungrouped achondrite paired with NWA 011, in the article I do for Meteorite Times. I have found some interesting write ups on the material but I don't want to just copy-paste any thing that sounds interesting. I was thinking that some of you may already have something written on NWA 4901 and it's pairings. If you are willing to share, I will use it in the article Micro Visions and certainly give you credit. Last month Bernd gave me some beautiful wide field NWA 3151 Brachinite micrographs to use.

[meteorite-list] Request for help in ID of a mineral
Hi, I was thinking some of you might know what this is. I bought it off eBay just this last week. 250342026204 It was sold as a meteorite and while I had my doubts, my curiosity was tweaked. The photos are quite good and they speak for themselves. My observation is, it is not iron! While it is highly attracted to a magnet (nearly like iron), it is brittle and not malleable. It is crystal structured and there is a section of fine grid shaped crystals. The crusted ends look like they COULD be sand blasted thumbprints but also look as if they could of been formed by molten material dropped on sand. If you have seen this stuff before, please share with me. Is it a nice example of a natural crystal or is it industrial scrap? Thanks!

Re: [meteorite-list] heavily encrusted dark grey interior - largefind?
Hi John, I agree with you. It looks like a meteorite. Certain meteorites have weird (Is that the official scientific term?) adhesion properties. I have seen some scoured by the desert sand and other who seem to grab every piece of sand/rock and make it stick. It must have something to do with the desert varnish that is growing around the native material or perhaps simple mineral migration due to weathering. I have a 7.3 Kg NWA that looks like it is completely encrusted in jewels. Fine sand bits all over! It is beautiful and unlike ant other I have seen. It has a brown interior so not a match to yours. I am embedding images. (I am sending this email to the list without pictures so if any one else wants to see the photos, just email me). Tom Phillips In a message dated 12/18/2008 7:59:14 P.M.

[meteorite-list] Polarizers way cheap! Big ones!
Hi list, All my images involve polarizers in one way or an other and over the last couple years I have had many inquiries of where to get polarizers cheap. I haven't had a solution other than scrounge them at yard sales etc. I just found an eBay seller that has 82mm PL for $8.50. This is way cheap for these big ones. I bought a couple and they are quality made in Japan with total extinction. The eBay # is 170282710765 Normal retail on a polarizer this size is usually several times this price. They are linier polarizers and not circular polarizers which is perfect for meteorite Xpol application. Check out my Micro Vision article in the Jan 2007 Meteorite Times Cross titled Polarized Light Hand Sample Examination. The link is http://www.meteorite.com/meteorite-gallery/Micro_Visions.htm This will give you an idea of what polarizers can do in meteorite examination and you don't necessarily need a microscope. With two 82mm filters you could make a thin section viewing set. These are big enough for a standard microscope slide to fit inside the filter holder. I'm not selling any thing, I just thought some of you might like to know. Also, while you are at Meteorite Times, check out this months MV on NWA 3151 Brachinite. It has three killer shots from Bernd Pauli in wide field cross polarized light. Tom Phillips **Make your life easier with all your friends, email, and favorite sites in one place. Try it now.

[meteorite-list] NWA 3151 Brachinite Greg's thin section
Hi Dirk and List, I am not up to speed on the latest pairings or the going price for each. I respect a quality thin section and this NWA 3151 Brachinite thin section just that. Even if it is terrestrial basalt, a good thin section is a joy and believe me, even a Lunar thin is a disappointment if prepared poorly. (I have a few). Most people do not have the contacts to get a fine thin section prepared regardless of how much material they may have. My passion is high magnification meteorite micrographs. I like to think it is more art than science since I am working with magnification far greater than what would be used in classification determinations. Some times the structures I see are breath taking and not at all visible in standard methods. My high magnifications require great thin sections. My next Meteorite Times article is on this slide so I don't want to get in the way of Meteorite Times viewings by sharing all the shots. MT will be posted in just a few days but in the mean time, if any one wants one I will send one full size 8mp image as an attachment, The image is taken at a magnification of approximately 400X with a field of view of 0.25 mm. Very cool structure in this image. Hopefully it will make you want to see the rest. (especially the shots by Bernd Pauli. Tom Phillips In a message dated 12/1/2008 5:38:20 P.M.

If we are using his service as an advertisement then send some $ his way.

If I had to maintain it and pay for the cost of keeping it free and available to every one, I would of closed it down long ago.

Re: [meteorite-list] What a watch!!!
Hey list members. Let's all get together and each buy one. That way we might get a volume discount! Tom In a message dated 11/18/2008 4:19:30 P.M. Mountain Standard Time, [EMAIL PROTECTED] writes: Hi, Pete, List, The original J. P. Morgan is reputed to have said, If you have to ask how much a yacht costs, then you can't afford a yacht. If you have to ask if the meteorite is real, then you can't afford to buy an $862,000 wrist watch! All I know is that I can't... In response to Martin's suggestion that you ask, please note the comments at the bottom of the page. They have been asked, and they ain't talkin'! My guess is that they mixed cutting dust into the paint used on the moon-phase dials. The same seller has a $60,000 meteorite watch with a speck of meteorite displayed, the name of which he does not disclose. In both cases, their cost for the meteoritic material is likely 0.01% to 0.001% of the cost of the watch. Sterling K.

Re: [meteorite-list] NWA 3368 Pink Eucrite
Very beautiful slice Mike, thanks for sharing! I'm missing the pick of the day as well. What a cool find with the meteorite powder! I think it really is magic.

Have been missing the meteorite pic of the day (does anyone have news yet?) and so I thought I would post a pic of my latest baby. A gorgeous eucrite with a subtle pink hue. A monomict eucrite breccia having large diogenite clasts and extremely fine grained basaltic clasts set in a light matrix having a pink hue! Purchased this slice from John Birdsell of Arizona. The slice is perfect! Thickness does not vary by more than 0.1mm and both surfaces are finished to the best polish for this material. Here is a pic: http://ca.geocities.com/[EMAIL PROTECTED]/metpics/NWA3368_34.8g_a.jpg My other pic of the day is from a small box of quack medicine I purchased. From 1910 this box is unopened and contains a vial of meteorite electric powder. A little bit of ephemera showing how 100 years ago meteorites were already considered magic. Here is a pic: http://ca.geocities.com/[EMAIL PROTECTED]/metpics/Meteorite_electric_powder.JPG Cheers!
