Re: [meteorite-list] Saw Blades
Hi List, Have to agree with Mike, I have used a lot of MK Diamond Saber blades and they are fine but they cost more than Pro Slicer and do not last as long. Especially since I cut sometimes dry. Pro Slicer blades do not seem to mind the occasional dry cut as much as other blades. A good price bargain as well.

[meteorite-list] Meteor Crater Plane Crash
Dear List, I just reread the article from 2008 in Meteorite Times and I don't have a lot of additional information to add. The actually crash information from the government reports is in the previous article from 2003 I think it was. But, as to what happened to the rest of the plane. Some was indeed removed from the crater and salvaged, but most of the remains were put down the shafts in the crater center which are fenced off now. Just the couple pieces a few feet long are all that remain. They can be found along the western edge of the crater near the bottom of the talus. As I mentioned in the article you can see them in binoculars or even in a camera with telephoto lens from the visitor center deck. And at the right time of the morning the sunlight coming over the edge of the crater rim will gleam off the fragments for a while. Makes a great photo when the bright shiny sparkle shows well.

[meteorite-list] Ad New ebook
Hi List Boy it has been along time since I posted to the list. First, I hope everyone is having a great new year and I hope that Paul and I will see many of you in Tucson very soon. A about a year ago Paul and I were brainstorming over a lunch and decided that we would like to venture out beyond the walls of the Meteorite Exchange and try writing and publishing an ebook to go up on Amazon. Well that book is available as of today. I hope you will enjoy it. It has been a fun project. It is for anyone interested in meteorites and anyone trying to learn what they look like. Its full of information on how to identify the different types and even lots of advise for those interested in giving hunting for meteorites a try. We put in enough photographs to make the pictures alone a great resource. It is titled METEORITES HOW TO RECOGNIZE VISITORS FROM SPACE If you see me in Tucson I will tell you the short story of how it got that title instead of another that had been its working title from the start.

And it had 171 pages on the iPhone. There are 78 photos in the book many are micrographs of meteorites taken in the 40x to 100x range. The other photographs are from hunting trips and wonderful shots of fusion crust and ablation surfaces and just great whole meteorites. Hope this helps answer the questions, enjoy.

Re: [meteorite-list] SHATTERCONES in TATAHOUINE
Hi Paul and List, We were discussing this in Tucson with Norm Lehrman at the IMCA dinner. I have taken some pictures as well that will be in my Jim's Fragments article coming out in a couple days in Meteorite Times. The shattercones are visible in larger pieces with the naked eye and are a fascinating feature. You are correct also about the orientation of the cones it seems that they are arranged in several different and intermixed ways. I took some high resolution photographs and have included two in the article which we hope everyone will enjoy. We are pretty excited about this too. Hope to see more information about what this records of the powerful event which drove Tatahoine from its parent body. Jim Tobin - Original Message From: Paul Gessler To: meteorite-list meteorite-list@meteoritecentral.com Sent: Wed, March 6, 2013 1:45:23 AM Subject: [meteorite-list] SHATTERCONES in TATAHOUINE I had a chance to cherry pick some larger sized Tatahouine nuggets from Alan Carion at the Tucson show and have noticed what appear to be shattercones on many of the facets? On every side that is fractured there are these chevron shaped interlaced lamellae/ flaring striationshowever they don't seem to have just one apex of orientation. On one surface I can see a cluster leading to the top as an apex point only to be met with one splitting the others going the opposite direction and also creating a small platform. It does make sense to me that Tathouine would exhibit this given its broken safety glass terminal deployment. I think the largest piece found was the size of a small grapefruit and if you tapped it with a hammer it would shatter into the smaller chunks we see more commonly. I guess what I am saying is that this mass in space must have been a heavily fractured structure and subject to multiple impact incidents followed by annealing then more impacts leaving over time heat and pressure multi directional percussion striation. In essence shattercones. Does anyone else see this? Any write ups on it that you are aware of? Got any examples in your collections that show what I am talking about? Let me here your thoughts please. I am stuck in an endless winter with plenty of time to ponder such things. I am aware that they may just be the natural clevage lines of the various minerals within.. but then why don't I see this anywhere near as dramatic in other meteorites? It would be neat to think of Tathouine as not just a unique Dioginite but also as some kind of relict impactite from the crust of another asteroid. ???

Hi List, I wanted to get this message sent last week but I am late as usual. My book on cutting and finishing meteorites is ready and can be ordered by emailing me. I am going to do the printing myself for the time being and put it up at Cafepress later. Its priced at $12 plus $6 shipping and I am taking paypal, cash and checks. I am going to try and have a few copies at Tucson but there won't be very many with me. Now that the business part of this message is done, here is the reason for me posting late. Grandchild number six was born last week and we have been having a great time with him. Collin Patrick is his name and for the ladies on the list that especially like the detailed information. 6 lbs, 12 ozs 20 inches blond hair that was spiked when I saw him the first time.

[meteorite-list] meteorite ceramics
Hi List, I posted a picture on FB and Google+ so I thought I might also mention it here. For 20 years I have diligently saved the cutting dust from my saws. A while back I started using the powder as a coloring additive to white ceramic clay bodies and to glazes as a very attractive brown coloring agent. I have made name plates for several dozen of the meteorites in my collection and other fun things. But I finished a mosaic of meteorite names and all but a few of the tiles in the mosaic are made of meteorite clay and glazed with meteorite glaze.

[meteorite-list] New Online Magazine
Hello List, Paul and I were a little sadden at the announcement by our friend John Walters that Voyage Magazine would no longer be published. We felt that doing something to keep the valuable material it contained flowing to the meteorite community was important. So we are going to be creating an online magazine at our website. We already have many articles that been submitted. But this will be an large expansion of that idea. We have contacted some of the authors that participated in Voyage and have received some answers back that they are willing to contribute in this format as well. This will be of course a free service offered as an additional forum for those with something meteoric on their minds. I have been the editor and designer of an online magazine as part of my work for 7 years. That publication has just in the last month been terminated. I hope I can bring some of that experience to this new adventure. We will keep you posted as plans progress.

Re: [meteorite-list] meteorite slices
Hello List, Gee it has been awhile since I posted to the list. My article this month in MeteoriteTimes is on cutting and maybe a little helpful. It mostly describes the cutting process and how I do lapping after cutting. So here is a little more info. It is very possible and actually fairly easy to smooth off a slice using the wet and dry type of aluminum oxide sandpaper. I used it years ago before I made the lapping equipment. Use it dry and be careful about the dust created. It comes in many grits. Start with the 150 and go to 350 or 400, then use 600 and lastly 800. Keep the old worn out paper since it continues to work a little and the worn out 800 gives a nice pre polish. I used a piece of hard smooth plastic to stroke the slice on so that it did not get the turned down edge. Polishing can be done on a piece of leather with any of the synthetic alumina based polished. They are white and don't stain the slice like rouge or cerium oxide. Clean up is easy. You will need to make a slurry of the polish about the consistency of heavy cream. Use distilled water to make the liquid. Stroke randomly around on the hard leather using firm finger pressure. Not so much as to crack the slice though. One point though which I also make in the article is, not all meteorites are enhanced by high polishing. Some lose visible detail as the matrix darkens with polishing. But, to be sure all slices should be smooth and saw mark free before selling. Happy New Year by the way, and looking forward to seeing many of you in Tucson.

[meteorite-list] diamonds in Canyon Diablo
Dear List, Bernd is usually the one with the early resources for topics that arrise on the list. But, I happen to have this one on hand so I will share it. one of the very first discriptions of diamonds in meteorites was: American Journal of Science and Arts Volume 46; 1893 pages 470-473 On the Diamond in the Canon Diablo Meteroic Iron and on the hardness of Carborundum. by G. F. Kunz. It is really quite a fascinating discription of both the occurance of the diamonds their discovery in the irons and of the chemical means used to extract them in those early days from the meteorite. The first creation of carborundum had only just been made and there is also a short discussion of how it was determined that the small crystals found in the meteorites were harder than the carborundum. They actually used the material extracted from the meteoritic iron at Tiffany's to cut and polish some surfaces on natural diamonds. All of this only a year or so after the first test pieces of Canyon Diablo were available. Have a great weekend, Jim Tobin __ Meteorite-list mailing list [EMAIL PROTECTED] http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Tektite Identification
Hi list, I seldom post, but could not resist this topic. The simplest test for identification of tektites from any volcanic glasses no matter how tektite-like they look; is to put a sliver in an oxy-acetylene flame and see what happens. Volcanic glasses will froth into pumice instantly and true tektite glass will do nothing but blind you from the incandescence. We have posted pictures of this before. Anyone interested can ask off list and I will send them pictures of samples that have been through this test. The funniest part of this is even after you do the visual examinations and other tests, when there is no doubt that the sample is ordinary obsidian or something similar. Most of the senders will insist that they are going to have more tests done. Because they "know" they are tektites. Just the same way it goes with meteor-wrongs. They "know" it is a meteorite because grandpa found it. Paul and I are in the midst of an ongoing research program with Stephen Pierce the staff geologist at Meteorite Times. He's taking absorption spectra of many natural glasses and man-made glasses. We are preparing the samples for him as thin two side polished flats. The result are very interesting. If you have not read the first portion of the results you can find the report in the back issues of Meteorite Times. It may be months before I say anything again, so let me take this time to wish you all a healthy and safe holiday season and new year full of joy.

[meteorite-list] Another mag bites the dust!
Dear List, After a brief conversation with Paul it was agreed that we would pull the MeteoriteTimes magazine down off the web and pick up our toys and go home. And I had a neat article already written for next month. We tried to offer valuable information and good science. What we fought the whole time was a battle to keep out the personal agendas of dealers who were contributors. Editing and worrying about any information concerning pricing. Careful that there was never mention of others dealers names by dealers, and ebay auction results and many more things. That is beside the fact that some of the material submitted was just badly thought out and poor science. Well, whether out of rushing around with the holidays and trying to get an issue out; we missed a couple things this month. They became matters of concern to certain individuals. Frankly, I have spent the week moderating the disputes of dealers in the meteorite business over things that we had little or no involvement in, except that they were written or done by contributing writers. This was never what the magazine was to be about. None of this has anything to do with the joy of studying meteorites and sharing stories. It involves egos and business. So when Paul called today with another problem created by one of our contributors, we came to the easy decision to drop the magazine. This reflects our general philosophy of life. As hard as we work, if the things we do in our spare time are not fun, we don't do them. Both of us have very little spare time. I work on average 55 hours a week in a high stress environment. Responsible for the entire operation of the production floor of a large printing company. He is working similarly stressful hours. As has so often be seen on this list, we are a community with some individuals who do not always work and play well with others. I have this week (and so has Paul) been in the nasty position of trying to balance long standing dear friendships with disputes created because we provided a place for the exchange of ideas. I will never choose losing friend over anything. It is my hope that when the dust settles that these individuals that I care deeply about will still choose to call me friend. I choose not to be hardened and ignore that there are friendships at stake. One meteorite investigator offended a dealer who is his friend. It occurred because of a photo used on our magazine. I took the blame for not seeing the offending element in the picture. But the thumbnail in our article did not have the element. The larger picture linked to our thumbnail which is not on our server was different. I took the blame I should have looked at every link to see what was there, probably a hundred links in this issue. Today, it is an argument over one person taking unfair advantage to promote themselves and their business; while not mentioning the activities of a similar kind by someone else. And these individuals are all good friends of ours. After raising four children and now having five grandchildren, I have despite my old nature become a pretty open person about my feelings. And all this saddens me and is frankly breaking my heart. To say the least it has taken the joy out of doing the magazine. With that said I offer an apology to anyone feeling slighted by anything we offered in the magazine. I have felt all week that there were maybe still black feathers in my mouth from the big meals of crow I have been eating. Paul and I spoke as I said rather briefly to agreed to this, and ended by saying we would send messages from our guts to the list, without discussing our posts with each other. I'm am just as interested as you to read what he says. Art I apologize to you also, this is the first non-meteoritic email I have ever sent, breaking one more rule today.

[meteorite-list] My last comment
Dear List, I just got home from work and found what the list has been busy with today and it distresses me more than the closing of the magazine. We decided to stop the magazine for a host of reasons and not because of any group of individuals or particular thing. It was the accumulation of things that made it no longer a pleasure to do. We never wanted anyone to be known or accused. We stopped the magazine to preserve friendships that our venue was putting in jeopardy because of a variety of factors we simply could not get good control of. I would ask that you not make our efforts of no avail by continuing to bash dear friends. They have made and will continue to make far more important contributions to this community over time than Paul and I ever will. They are far more passionate people about meteorites and will serve to expand the scope of our field of interest to a much greater degree than we could. I would ask you all to appreciate that they are all caring individuals, that have feelings, and those feelings have been hurt, today. Nature hates a vacuum some other publication or discussion group will appear. Perhaps this list can provide similar material to what we offered, that would just be wonderful. Paul and I really enjoy going to Tucson and seeing everyone, we have always entered every room with a smile. There have always been only friends there. That is my wish for all of you that in every suite you visit there will always be a friendly welcome without hard feelings. I don't know what I will be thinking this year. But, I am hoping for the best year ever. I for one am not going to ever say more about this, and look forward to the next time I see all of you.

RE: [meteorite-list] Oldest Collector
Hi Alan, 1963, that's when I sent my first piece of basalt to Denver. I received a nice card, a couple leaflets, and a copy of "When a Comet Strikes the Earth" back in the mail.

[meteorite-list] Australite Tektites
Hi List, Thank you Michael B for the kind words about my thin sections of buttons. That was a long time ago. There is a micrograph of a picture of one of those I still have in the September 2003 issue of Meteorite Times. If you go to the current issue and use the link to back issues which is near the top of the page under the rotation banner ads at the top center select article and choose Tektite of the Month. Here is a list of other articles with great pictures of buttons from Tektite of the Month. Sorry I don't have time right now to copy all these links into this message. June 2007, May 2007, December 2006, February 2005, October 2004, and the one mentioned above with the thin section picture September 2003. The button type tektites would appear to be cold solid bodies that return from near space at velocities high enough to ablate and the forward surface melts. The liquid glass rolls up like a jelly roll often not welding well or at all to the shrinking core body of the tektite. Often the stresses are so great that the whole front of the tektite called appropriately enough the "aerodynamic stress shield" will detach. The reasons for this are debated still. I personally lean somewhat to a thermal shock of somekind between the cold core and the heated outside. But would not get into a fight over this, there may be a better reason for this detachment of the forward ringwave surface and flange. The fact that many are found with adhering pieces of ringwave and flange would seem to support that internal fracturing happens. The flat surfaces characteristically seen on cores of ablated tektites would indicate to me that fracturing happens as well. If ablation continues long enough the rolled back material and the unwelded narrow valley which forms next to the cold core will proceed to such a degree that the bottom of the valley will actually reach the front surface that is ablating and the ring itself can detach. Very rarely these rings have been found unbroken as separate specimens. I have personally only held one complete detached ring. But holding that one was exciting. The ringwaves are a property that they receive from a combination of their spin the motion of the liquid material that is rolling up and the air currents against the face as it slows down and cools. Sometime this intricate pattern will be very waffley if the flange itself is thin enough. The ring waves are one of my favorite aspects of ablated tektites. I will return to lurking.

Re: [meteorite-list] Request: Review of the book - Tektites in theGeological Record
Hi Pat, It has been several years ago now but, when the book first was coming out I did a review of it in Meteorite Magazine. A quick summary of the review would be that it is a pricey book that has a lot of new information about tektites and a good amount of new material not really easy to find elsewhere on recent microtektites and clinopyroxene spherules discoveries. There were a few minor things I noted that were off track but it is a good book. Though as you noted you have to really love tektites if the price is now $130 for it. Wish I knew what issue of Meteorite the review was in but maybe I can find it on my hard drive and send you a copy. Or maybe one of our list friends can give us all the issue info.

Re: [meteorite-list] question for thin section collectors
Hello List, Ward Geology has slide boxes and slide cabinets for holding from 100 to 1000 slides or more.

[meteorite-list] TS slide boxes
Hi List, I must not have anything better to do today. Miners Incorporated also has petrographic glass slide boxes and wooden cases. The nicer wooden cases are at https://minerox.com/index.cfm?fuseaction=product.display&Product_ID=1356&CFID=1553105&CFTOKEN=51568253 Just click the "choose one" to see the prices of the large capacity cases. These are still fairly well priced compared to my old 1999 printed catalogue. Best, Jim Oh by the way the size is usually 28 x 48 mm but they do come in 26 x 46 mm, they are even listed as 27 x 46 as in Wards Catalogue. But, my experience is they all will fit in the boxes. The 25x45 is the size of the cover glasses most of the time. I do wish they could just make one size. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Ad
Well this is a first for me. An advertisement. My greatly expanded book on Meteor Crater is complete and available for purchase. Included in the volume are reprints of the original reports on the crater by Barringer, Thilgman, and Gilbert. The cost of these papers alone would be several times the cost of my book were you to buy the reports today. But, the narrative tours of the rim and the floor should be very entertaining for anyone who has seen the crater but especially for people who have not. I tried to make them as close to being there walking as I could. You can not go to most of those sites at the crater anymore. The book is pretty rich in photographs and stuffed with information. It can be seen and bought at: http://www.cafepress.com/Craterbook Looking forward to greeting many of you at Tucson in about a month.

Re: [meteorite-list] Tektit "Muong Nong" and cutting
Dear List, Paul and I have several large pieces of Muong Nong that we have been cut and polished to near optical flatness. It is a long and difficult process taking about 60 hours. First grinding on a vibrating lap and then polishing on a wet lap charged with cerium oxide. Polishing is about 40 hours of the 60. But the lap s can handle several pieces at the same time. The results are fabulous. I don't know if the specimens are currently in our catalog at meteorite.com but maybe we can feature them as the Tektite of the Month in the next Meteorite Times. The polished surface is so flat that the microscopic differences in strain on the glass that are relieved at the edges can be seen in the surface. They have been at our tektite parties maybe some of the attendees can comment further. It has been one of the most challenging and rewarding things Paul and I have done with the vast amount of Muong Nong we have. Wish we had time to keep the lap running more. Looking forward to seeing many of you at Tucson.

[meteorite-list] Polished Muong Nong
Hi List, Sorry I should have looked before the last post but we do have some specimens of cut and polished Muong Nong still up to see. All but one have sold but the pictures remain. http://www.meteorite.com/catalog/australasian/thai_mn/Muong_Nong_Polished.htm The best picture is of specimen MFT-P1 which Paul has shot with the reflection of a plant outside a window showing on the face. This will give you some idea of how flat the surface is. Some of the other specimens were chosen because of the great differences in the glass that they have to show . One is very frothy on half and the other portion is very solid. One is very banded. Take a look, enjoy. We have been leaving the pictures up since they are so nice, but I guess we should put some more specimens up to sell. We sort of hate to let these babies go though. Nothing like a tektite thread to bring me out of hiding. Best wishes, Jim __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Hi List For those of you who have seen the new issue of Meteorite Time you may have noticed that Anne in her article about the Monnig papers on the Harriman meteorite that one note was in code only partly decoded. Here is the rest of that coded message. . in Chattanooa and had turned the matter of recovering possession over to an attorney. How much luck do you think then will have. Fortunately I never did write _ones. Do you have any further instructions in the matter. The spelling of Chattanooga was wrong in the coded message the cipher for "g" was missing in the word. Also, will is will not WE'LL as I think it should be. But, he had not editor in his coding writing. Also, I could not definitively determine the letter where the _ is, which seems to be a name. Because, "c" is used only once as a cipher and X, Z, and Q are all available and Caps can be more than one cipher it seems. Jones was my guess but I leave the answer to someone else. Thanks Anne it was a fun project.

Thanks Shawn for the link I would have missed this and it was fun to look at. The information is quite detailed for each specimen you just have to click on the photo on the group catalog page and a page for each specimen appears scroll down and you'll get all the info. I thought it was a very nice description and the size and weight are there with an estimated value and whether there is a reserve or not. A condition report for the specimen can be obtained by request. The information on the $12,500 Sikhote Alin is: "Overall Measurements: 8 x 6 x 6.25 inches (20.32 x 15.24 x 15.88 cm), weighs 7.49 kg (16.5 lbs.) Offered at no reserve. Estimate: $25,000 - $30,000."
