[meteorite-list] meteorite classification costs
The question comes up from time to time about the cost of classifying a meteorite and also regarding turn around time. The actual cost varies significantly depending on the type of meteorite. For example, base cost for an equilibrated OC 1) thin section $30 (the cheapest part of the process) 2) two hours on a microprobe $200 (machine costs at cheap university rates and not including the time to set up the probe which can take several hours) 3) operator cost are more difficult to assess but I would imagine their two hours on the probe plus another hour or two of putting the data together and submitting it - so lets say another $200 minimum So around $500. Now for an unquilibrated OC (since you need a good spread of Cr2O3 data) I would say at least eight hours on the probe so over $1000 Now if you need oxygen isotopes, then this by itself could easily cost $1000 (plus the $1000 for the rest of classification). But good luck finding a lab to run the 16,17,18O isotopes. Most isotope labs only run 16O and 18O. In reality, the true costs are not passed on to the owner of the stone, but instead are borne by the institute undertaking the work. Some classifiers will charge a nominal fee to cover probe time, but again that is a small fraction of what it would cost if you wanted probe work done in a lab at industrial rates. Turn around time - days to years depending on how interesting the stone is.

Re: [meteorite-list] OT Radiation Dose Chart
Humanity has believed in evil spirits pretty much forever, for 400-500 centuries. Then, a few centuries ago, some odd Europeans pop up and assert, with evidence, that the world is rational, perceptible and understandable? Yeah, that's going to make a big impression on the human unconscious... As for radiation, it's a perfect fit for evil spirits: invisible, imperceptible, and deadly; it's the epitome of Bad Mojo. And in certain East Asian cultures who traditionally believe in evil spirits, all the doorways have right-angle baffles set up so that no line-of-sight can pass through. Why? Because evil spirits, devils, demons and such can only travel in a STRAIGHT line -- like radiation. Cue the Twilight Zone theme... Sterling K.

Re: [meteorite-list] Ethics question?
Richard, Bill, Barrett and List, Personally if a meteorite were glued together I'd want to know, but I'm positive I could tell it were glued together. Now, to be honest with you, unless the person was an expert at gluing meteorites, I'm sure most people could tell it was glued, I would think. If you had a great deal of experience at gluing Native American or Pre-Columbian artifacts and or stone or metal objects together most people could tell that also, and in any case you should always advise someone it's glued if you were selling it. I would think most people selling their meteorites at that point would sell them separately and they would probably make more money selling the separate pieces than as a whole. As you know every year the specimens are getting smaller and smaller, and then you're down to micro-mounts and dust. I recently bought a decent crumb, about 144 mg of New Concord that I can see and a 19 mg Weston, which is just too small honestly for me, and I'd rather have a 1 gram piece but none were available. We all know dealers buy meteorites and break them down to smaller and smaller specimens and they make more money per specimen that way, since it's more money per mg or gram. This is also helpful to beginners or those not wanting to spend a great deal of money and for those who want to have a specific meteorite in their collection and the small specimens do allow this. I recently bought eleven very nice meteorites ( 9 separate names) and there were 2 pieces of Agoult that fit together that were sold separately, a 1.6 gm and 1 gram piece. I was happy with them, and the seller made more money probably than if they hadn't been broken and sold as a 2.6 gram specimen. I also bought his 2 Bruderheim pieces, a 9.7 gm and a 1.0 gm piece that fit together like a puzzle. I'm happy, and they look nice, and if I sell them I'll probably sell them separately too since again if they broke accidentally or were broken to sell separately and to make more money, either way is fine. I bought them and someone else will also. Honesty is the best policy. Take care and may a large Lunar or Martian Meteorite fall into your yard today.

Re: [meteorite-list] The Human Presence in the Solar System
The nature of this list means that I am certainly preaching to the converted but I'll have my say anyway. Research and discovery for it's own sake is uniquely human. It is true that it costs a lot of money but we all know it's very little in the grand scheme. As a gross oversimplification of things, mathematicians find out how numbers play, physicists work out a practical application for the maths, engineers find something useful to do with the maths and EVENTUALLY, through the sheer endeavour of it all and the processes we go through, the whole of humanity benefits. It's a similar story is for all sciences. We shouldn't necessarily be doing things with a view to long term benefit. We should do it because we are human. The long term benefits will come by virtue of us having achieved the remarkable.

Re: [meteorite-list] Ethics question?
Good Morning Barrett, I Found a meteorite yesterday while hunting and it was a broken piece. So I looked around a little more and found the other broken half! I messed with them a little and proved they go together in a puzzle. Awesome piece. When my hunting buddies all got together a little later, one of them commenteddon't glue the thingwhich I would not do anyway. The fact it was found in broken pieces and the fact I actually found the larger second piece, I feel, this is unique to the find and I will never glue these. When I found my first ever meteorite, I made a lot of mistakes with it. First, I did notice it was a fractured piece. When I put it in the vice, I cracked it in half. I knew immediately I made a mistake! However, what was neat about that is there was a complete 1 gram iron nodule (speer) in the middle of it...just like the kind of little irons found in the same area. So, I learned a few things while this happened. I was sick that the thing cracked in half...being my first ever stone, but it worked out okay. Since then, a chunk of it was cut and sent to a lab. I ended up gluing this one back together but I am not sure I would do that again. I have another meteorite I bought at Tucson to use as a study piece. It became a puzzle sometime between where I bought it and home. I do not intend to glue it. I kind of decided it alters the nature of the stones when gluing, but that is just my feeling on it. I do not believe you have any ethics issues gluing you own stone. I think if you intend to sell it or show it and do not disclose it's been glued, then ethics come into play.

Re: [meteorite-list] Ethics question?
Richard, Bill, Barrett and others I agree with Brian Cox in that it is important when repairing specimens to ensure that it is clear that this has been repaired and that it is not being passed off as anything otherwise. Artefacts are often repaired when there is sufficient material remaining, or if it will add to the scientific or academic value of the object. But it is usually made very obvious that it has been repaired. Mineral specimens do get damaged and repairs are a day-to-day job for our conservators. These are done as invisibly as possible, but the repair is noted in detail on the specimen label. I guess it is up to the owner to decide what to do. Without seeing the pieces it is difficult to give you anything other than general advice.

Re: [meteorite-list] Ethics question?
It depends on the meteorite. I find it acceptable to stabilize common meteorites with bonding agents before cutting if it looks like it will break apart during cutting. One of the reasons is safety, the other is conservation. I wouldn't want a 30 pound monster flying apart in the middle of a cut on the Judge,a 24 Highlands Park Saw. This saw can bring on tremendous pressure to ensure consistent cutting speeds which are important to near flawless cuts. I usually dissolve the bonding agent after the cut if I feel the piece will stay together long-term. I always note if a specimen has been permanently stabilized but tend to avoid meteorites that require it. I rarely cut puzzle meteorites because they tend to damage blades and require a lot more work. The main thing is to use bonding agents that can be completely dissolved later if future study is necessary. Every specimen used in thin-section making is stabilized the same way using an optically correct epoxy before preparation. The main thing is to conserve material the best way possible. One time a long time ago when I was naive to such things, I was temporary fooled by a meteorite in a dark Moroccan mud-hut. I saw what looked like a thick glass vein running throughout the shiny-black meteorite and purchased it on the spot. I later looked at it under a microscope and saw bubbles in the glass vein. I then probed it with an explorer tool and found that it was soft like Elmer's glue. To make matters worse, the shinny black crust turned out to be shoe-polish. I sure wish the Moroccan dealer would have been honest in the first place. As it stands, I will never purchase a piece from this particular dealer again who preys on tired travelers. I would have never suspected such treatment in the Sahara desert but learned quickly that their are unscrupulous people all over the world. It was my fault for trusting him. I felt stupid for not checking it out better in the first place but a 1/2 day jet lag and lack of sleep will effect proper judgment. If he would have simply mentioned the fact that it had been treated, I would probably still being doing business with him.

[meteorite-list] Ed Weiler's plan to flood the meteorite market
Hi Everyone - Nine years ago I wrote about NASA's Ed Weiler's plan to flood the meteorite market by putting too many meteorites on it all at once: http://abob.libs.uga.edu/bobk/ccc/ce091702.html And lo, it is coming to pass. From Alain on the mpml mailing list: To all who care to read what follows - I believe it is very academic (meaning not too efficient) to talk at length about statistics, the work needs to be done. I don't share Ed's statistics, but when the next one, even a small one, will fall, it will be too late to talk about statistics. Right now detection work is only done efficiently by NASA supported programs. It is a real shame that no other country in the world has moved a little finger in this respect (decisions are taken in the academic circles, therefore are not taken). The only thing I can say, apart from thanking NASA for its current effort is that I hope they will be able to do even more. Hopefully they understand quickly that time share telescopes are not the way to go. When PS1 brags about finding 19 NEO in one night, this is not so much higher than the current records obtained the 1.5m Catalina. I was there with Andrea Boattini last September, and they had detected 16 in the previous night (and didn't make a press release for the occasion :)). This is a 1.5m telescope in a not so exceptional site, with a 16 megapixels camera. PS1 is a 1.8m telescope with a 1.4 Gigapixel camera, it should find hundreds of NEOs per night, and in fact has to, if it wants to detect the number which has to be detected. That tells a lot about the very low efficiency of PS1 when it comes to asteroid detection. A full time PS1 would become interesting. A 2 nights per month is basically worthless to attack the problem of finding all 140m asteroids in a short time. So far this year, Catalina has discovered 174 NEOs, PS1 31... (http://neo.jpl. nasa.gov/ stats/ ) If you compare the theoritical capacity of each telescope, PS1 is around one thousandth of what it could be doing. The same will happen with the Large Time Share Telescope or whatever its name. LTST, LSST, you name it. Hopefully NASA can find the funds to get a large full time asteroid survey telescope instead of falling in the time share scam. There is an estimated 25000 140m asteroids to be discovered. You'd need to find 2500 per year in ten years. That means at the beginning of the survey to discover (and follow up) about 10 such objects per night, every night (full moon and cloudy nights included). This is what is needed, and it won't be done observing twice per month. Alain (It is sad that Alain did not realize that PS1 was funded by the Air Force) E.P.

The actual cost varies significantly depending on the type of meteorite. For example, base cost for an equilibrated OC 1) thin section $30 (the cheapest part of the process) 2) two hours on a microprobe $200 (machine costs at cheap university rates and not including the time to set up the probe which can take several hours) 3) operator cost are more difficult to assess but I would imagine their two hours on the probe plus another hour or two of putting the data together and submitting it - so lets say another $200 minimum So around $500. Now for an unquilibrated OC (since you need a good spread of Cr2O3 data) I would say at least eight hours on the probe so over $1000 Now if you need oxygen isotopes, then this by itself could easily cost $1000 (plus the $1000 for the rest of classification). But good luck finding a lab to run the 16,17,18O isotopes. Most isotope labs only run 16O and 18O. In reality, the true costs are not passed on to the owner of the stone, but instead are borne by the institute undertaking the work. Some classifiers will charge a nominal fee to cover probe time, but again that is a small fraction of what it would cost if you wanted probe work done in a lab at industrial rates. Turn around time - days to years depending on how interesting the stone is.

Re: [meteorite-list] OT Radiation Dose Chart
radiation dose is realy wierd. You can get more radiation from an hour in the sun getting a tan than from being scanned at the airport. A tanning bed or a few hours in front of a cathode ray tube. Then you can replace the lantern mantle on your camping lantern and breath in more radioactive material than you could ever get anywhere else. Its not so much what you get exposed to. Its how much gets in you. Like drinking water or eating food contaminated with radioactive iodine. Iodised salt does provide some protection and an ordinary dust mask also helps. One thing that is more damaging in most places is the latex rubber dust you breath in driving to work and back from your tires. Without the acid introduced into your lungs from second hand smoke there is nothing going to remove the rubber dust from your lungs.

Re: [meteorite-list] Oxygen isotopes
Good Morning Laurence, Carl and the list, I am interested in this thread and honestly, I think Laurence's estimate on labor rates is a tad bit low although I understand it was a guesstimate. Typical loaded labor rates is very high if all is considered...hourly wages/med benefits/retirement plans, etc. A couple of things I am interested includes how are these departments are funded?? Where does the money come from to support the departments? Secondly, comparing to the early 1990's, how many meteorites were studied/processed then compared with today?? And, how much has technology advanced the state of the art? Does the specimen owner actually get charged any of the costs of the testing?

Re: [meteorite-list] Martian Sedimentary Rocks: Where are they?
Greg, Maybe you are throwing Mars rocks? Again, this has also been posted before and rejected by some but, it is the only *real* study we have by which to judge. And accordingly sedimentary rocks developed white crust or none at all. Why ignore the science? see link; http://www.spacedaily.com/reports/Stone_6_Artificial_Meteorite_Shows_Martian_Impactors_Could_Carry_Traces_Of_Life_999.html Again, Blain's gun might narrow down the search.

Re: [meteorite-list] Martian Sedimentary Rocks: Where are they?
sedimentary rocks be they cabonates or other oxides when exposed to water after heating have an exothermic reaction. Thats why the same minerals are used to melt ice on roads. Any fusion crust exposed to ice or terestrial weathering would be gone in a few minutes or hours. Take a piece if bog iron or limestone and heat it to mak a crust. Then toss it in some snow. A few minutes later it has no crust. And most of it will dissolve to nothing after a few years. Sedimentary rocks were made by and are disolved by water and weathering.

[meteorite-list] Sedimentary Martian Meteorites
Hello Steve, Carl and List, Thanks very much for the comments. I am at a distinct disadvantage, not having a background in geology so please bear with me. I understand exothermic processes but... The oldest sedimentary rocks are found in various places such as Greenland, Hudson Bay in northern Quebec, Western Australia, etc. These rocks are billions of years old, yet they are still recognized as sedimentary rocks. Why? Should they not have disappeared long ago? Would you say these rocks were never exposed to heat, water or weathering? I would think that traveling through space, where obviously no terrestrial weathering occurs, potential Martian sedimentary rocks would not undergo weathering until they landed on Earth which would be on the order of millions of years ago. Much more recent than the oldest Earth sedimentary rocks. It may very well be that the reason we don't have any Martian sedimentary rocks in our collections (scientific and otherwise) is because they have all weathered away or at least to the point where we would not recognize them as being Martian, or even meteoritic, in origin. Yes, I have looked at Dr. Irving's site. http://www.imca.cc/mars/martian-meteorites.htm It's a great site and is on my favorites list but he doesn't speculate as to why we have no Martian sedimentary rocks, which is what I am most interested in. -Walter __ 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
