Re: [meteorite-list] Who prepared the first published meteorite catalogue?
Thanks for bringing Lucas' catalog to our attention Mark. I wasn't aware of this interesting work until you mentioned it. As far as early ctalogs exclusively featuring meteorites are concerned, you may also find Ernst Florens Friedrich Chladni's meteorite catalog interesting. Chladni published the catalog of his personal collection in 1825 and thus it predates at least Cordier's 1837 work (though not Schreiber's appendix to Chladni's Feuermeteore as you pointed out correctly). The complete title of the work is E.F.F. Chladni's Beschreibung seiner Sammlung vom Himmel herabgefallener Massen. Nebst einigen allgemeinen Bemerkungen. The descriptive 40 page catalog was printed in Kastner's Archiv fuer die gesamte Naturlehre, Vol. IV in Nuernberg in 1825 (p.200-p.240).

The trouble with assuming that the photo on the left is a cleaned-up version is the following, which I'd like to condense and then apply. #1 Photo 1: meteorite 1/2 buried Photo 2: meteorite on surface #2 Photo 1: meteorite clean Photo 2: meteorite covered in dirt #3 Photo 1: meteorite in undisturbed soil, surroundings Photo 2: meteorite on surface, may have been moved (dirt/rocks on surface would suggest otherwise, but possible). Surroundings themselves look undisturbed. #4 Photo 1: meteorite in sandy area, small rocks Photo 2: meteorite in rocky area So, #1. The photograph on the left shows a meteorite well-embedded in the ground. And the surface soil has been moved in only two locations around the entire meteorite (#3). There is a left-handprint that clearly breaks up the uniform texture of the undisturbed ground in front of/to the left of the iron, and it looks as though someone poked the ground a few inches in front of the pen used for scale. The rest is undisturbed desert pavement. If you were to step on it, you'd change the surface -- and it won't be the same until after the next rain. Apply #4. They clearly didn't move the large rocks from around the meteorite on the right because the ground around the meteorite on the left is almost entirely undisturbed. The meteorite on the left is undisturbed as well (and it's half-buried, as opposed to being on the surface); compare to the photograph on the right. Both meteorites have tapering ends. But in the photograph on the right, the tail-end is clearly several inches above the ground. The photograph on the left shows no such thing. That meteorite (on the left) is really sitting *in* the ground, as opposed to on top of it (again, compare to right-hand photo). I suppose you could chalk this up to an optical illusion, but I really don't think that it is. Take a look... Again, the meteorite on the left is half buried, yet clean, and in an undisturbed, rock-free area. The meteorite on the right is sitting on the surface of the ground, is covered with rock and dirt, and is also sitting in a relatively unaltered bit of desert. This is what happens if you step on similar ground. http://vormedia.com/images/mono2037.jpg http://media1.z2.zoopy.com/media/2009/05/20/7304/42304/original.jpg Compare to each meteorite photo. They're both sitting in pretty pristine desert. Not even a footprint. It's a textural thing. If you're saying that they cleaned up the photo on the right to make the one on the left, you're going to have to explain why they wanted to bury the iron deeper into the ground than it was in the first place, how they did so without disturbing the desert pavement in the immediate vicinity of the meteorite, and how they removed the rocks and made the new surface look as though it had never been disturbed. I've taken far too many in-situ photographs of meteorites in desert conditions; even stepping on a hard-pan lakebed can leave visible traces in photos. Both photos on this site show the meteorite(s) in undisturbed terrain, and yet one is sitting in the ground, and one is sitting on top of it. If we are looking at two photos of the same meteorite (which I doubt), the meteorite must have been moved, but if it was, it was from the left photo to the right photo. And whoever was carrying it was able to set it down without even stepping on the ground visible in the photo. It's hard to do that when you're carrying nearly 180 pounds. I have no agenda/reason for saying this; it makes no difference to me whether or not there are one or two such irons. But I'm seeing double, and they really don't look like twins.

Re: [meteorite-list] Gebel Kamil webpage
The effects of sand abrasion (corrasion) and chemical weathering (corrosion) of objects on a desert surface, apart from other factors, depend considerably on the texture and composition of the original surface, but also on the dimensions and the depth to which an object is buried in the soil. It does make a difference whether the surface to be attacked is coated by a smooth layer of magnetite and other iron oxides (fusion crust), or whether the surface is a shear surface without any protective coating (and with large micro surfaces inviting contaminants to adhere). Also the forming of caliche or calcrete due to evaporation and condensation processes in hyper arid regions is usually limited to a very narrow zone close to the surface. Parts of objects buried beyond this zone or protruding above it, are affected in a much lesser degree. This effect can be observed quite well on Kamil shrapnel. These conditions allow to interpret caliche deposits on desert meteorites in certain cases as markers, indicating previous ground levels of deflation zones. The strongest activity of chemical weathering in hyper arid environments is limited to this very zone as well. If we look at the majority of the corrasion activity, which is one of the factors responsible for the characteristic sub-milimeter pitting on the Kamil-shrapnel, it is limited to a specific zone as well. At normal prevailing wind velocities the leaping motion of quartz sand grains (called saltation), which abrades the surface of an obstacle, is usually limited to 0 – 5 centimeters above the ground. But most of the damage occurs in the lower region of the saltation zone. Thus, conclusions drawn from weathering patterns of iron objects of different sizes, surface qualities and burying levels should be considered with caution.

I initially thought that the iron might simply have been rolled over - but take a look at the patina visible in each photo. The surface of Gebel Kamil irons varies greatly: especially the contrast between exhumed and buried surfaces. Exposed surfaces typically exhibit a dark patina and sometimes corrosion pitting. Buried surfaces are often better-preserved, but look entirely different; they're rusty.

Re: [meteorite-list] Gebel Kamil webpage
I happily acknowledge your experience Jason, but that is not the point. I can only speak for myself, and I do not base such statement on a photo without any chance to study the evidence in situ. By the way, the original source of both pictures you quote is the Museo Nazionale Antartide, although the source you quote does not give credits and has obviously changed the aspect ratio of the second photo to make it fit the website template. In the supplement to the Science-express article of Folco et al. on the Kamil crater, the left photo has the original caption: An 83 kg meteorite specimen found 230 m due north of the crater showing regmaglypts The photo on the right, which is from the Museo Nazionale Antartide Kamil crater website, has the original caption: largest recoveredmass ca. 80 kg. Luigo Folco from the Museo Nazionale, the head of the Kamil expedition, wrote in the express version of his article in Science, that the finds of his team consisted of shrapnel except one individual fragment of 83 kg”.

I thought the facts were rather odd and out of date, since no one listens to 3 hours of radio anymore, not even old me with my oldies, since everyone is on their ipod. If I see someone with a CD player attached to their arm it's only because they're running along the lake, and most have switched to ipods, and most people barely watch 4 hours of TV anymore.

I'm sure the book stats have changed, but with the computer and internet, which that ancient 2003 article Didn't even mention is where most people get their news these days (I haven't bought a newspaper in two years) and people read more online or with their kindle or their ipad than a real book.

[meteorite-list] Kainsaz CO3 Individual - Crusted Mt. Tazerzait - 14 kg Gibeon - AD
Ladies gentlemen, I have been offered two superior collection pieces which are beyond my own acquisition capabilities, and which I would like to make available to other curators/collectors. Additionally I’d like to take the opportunity to offer a meteorite from my own inventory. The first specimen is a fusion crusted 340 g individual of the Kainsaz CO3.2 carbonaceous chondrite which fell near Muslyumovo, Tartastan on September 13, 1937. The specimen was found in April this year and is one of only two pieces found within the last two years. It was recovered from a depth of 12 cm in the central part of the strewnfield. Although Kainsaz is a historic fall and one of only six CO3s which have been seen to fall, the owner priced it at just 25 USD/g. Photos including an in situ shot can bee seen here: http://www.meteorite-recon.com/images/Kainsaz_340g%20.pdf The second meteorite is a crusted 1.8 kg fragment of the L5 chondrite Mount Tazerzait, a witnessed fall from August 21, 1991 from the Republic of Niger. In contrast to most other chondrites the highly porous material underwent very little compaction and rather resembles a pyroclastic welded rock, much like Baszkowka. Mount Tazerzait has been extensively studied. It is believed to represent material resulting from gravitationally induced accretion of a hot cloud of debris on the surface of an asteroid following the collision of two planetesimals. The price is 1.9 USD/g Some photos may be found here: http://www.meteorite-recon.com/images/Mount_Tazerzait_1.8%20kg.pdf The third specimen is a heavily sculpted 14.7 kg Gibeon iron meteorite with deep regmaglypts and uncleaned natural patina. A side note for the art connoisseurs: this meteorite was part of the installation “Cloud Paintings” by Sigmar Polke displayed by the NY based art gallery Michael Werner on the art basel in 2009. The price for this exceptional display piece is 490 USD/kg. Please view some photos here: http://www.meteorite-recon.com/images/Gibeon_14kg%20.pdf Thanks for your interest, have a great day!

Re: [meteorite-list] Labeling specimens
Ed, Count and list, I'd like to second the count's and Ed'd considerations regarding numbering your specimens. Of course most private collectors recognize their individual meteorites. Mix ups are not so much a problem during one's lifetime. At least not unless we don't start to juggle with a couple of hundred specimens which we lend to exhibitions, for research, or have our kid's kindegarden pals sort through them. However, as Dave Gheesling recently has pointed out in his excellent article on Temporary Custodians, sooner or later every collection will be broken up, separated or turned over to the following generation. If no written track on the individual specimens has been kept, the knowledge on these treasures will perish with the previous owner. Dealer and museum curators can tell you stories of collections offered by heirs, where all the information that was passed with a specimen, if any at all, was a name on a crumpled paper card. When pieces are not individually packed, which is also quite common, no safe attribution of specimen cards and meteorites can be untertaken at all. Photos are one way to assign identity to a specimen, but unless you do not have the patience of a Zen monk and you are faced with a collection that has 20 small Gaos, Pultusks, Wilunas and Zags in it, you soon discover the limits of this approach. I very much encourage everyone to undertake the little effort. All that it takes to preserve the identity of a specimen is a printed or digital inventory list, which contains some sort of distinct, non-ambigous assignment of a specimen and the information associated. The pendant should be applied directly on the specimen itself, it's the safest way. Painted numbers in my experience have prooven superior, but other means of course are appropriate too. Safely storing, better publishing or distributing your collection catalogs of course is crucial to preserve that information.

As he points out, Lylle, Huss, Nininger, and others have done it, and so do many museums. I worked (volunteered) with the Curator of Collections in our local Science Museum in 2008 to inventory their collection. In about 97% of all cases, the Accession Number was painted directly on the item in an out of the way place - be it a meteorite, mineral, or other piece in their collection. The exception being, of course, where painting was impossible or problematic. Stick-on labels can fall off as the adhesive can deteriorate with time. I have purchased meteorite specimens with an adhesive label applied to the cut/polished surface, and that is not a problem for me unless the label falls off. Painting the numbers on eliminates that problem as long as the surface is clean, dry, and free of loose particulate matter. One of these days, when I get some time, I plan to label my large-enough specimens with painted-on numbers, do a photographic record, and set up a database for my collection. I have a decent DSLR, bellows, and macro lenses. With a little practice and good lighting, I hope to be able to master macro photography.

Re: [meteorite-list] Lovina Iron
Thats awesome news Darryl, my sincere congrats. As Matthias already pointed out, if this iron was not from space, where else could a mass so enigmatic and so utterly different in appearance come from? I appreciate the fact that its extraterrestrial origin has been confirmed now. Given the difficulties of determining the meteoritic origin, one is tempted to expect further surprises along with the proceeding chemical and metallurgical analysis. As to the meteorite's particular morphology: I personally like the idea that in the warm shallow waters of the Indopacific the erosive forces of nature are working in unison with the local principles of artistry and style.

Re: [meteorite-list] LOVINA REVISITED
Thank you for the new evaluation Darryl. Although this is a regrettable development one must not forget that you took the initial risk of acquiring such exotic material, which alone is a remarkable achievement. I very much hope that this experience does not discourage you to venture similar acquisitions in the future. If it wasn't for people like you, most meteorites of similar caliber would never see the light of public. Set backs are a natural part of this business and there are very few dealers who would not subscribe to that. Svend Darryl Pitt dar...@dof3.com hat am 9. Dezember 2009 um 09:15 geschrieben: Well, I had an interesting day today This morning I met with Roy Clarke, Linda Welzenbach, Cari Corrigan, Glen MacPherson, and Tim McCoy at the Smithsonian. During our get- together Tim made several observations as to why Lovina could very well not be what it has been made out to be---which is to say, a meteorite---and why more work must be done. In Tim's words 1) The sulfides are not simply troilite and appear optically to be multiple phases, including one that looks like the Ni-rich sulfide pentlandite. 2) Although the presence of the octahedrons has been attributed to weathering, the structure of the remainder of the meteorite shows fine stringers of sulfide, not large areas that would easily weather out leaving such octahedron. 3) On one polished slice, the sulfides clearly wrap around one of the indentations, rather than the cross-cutting relationship one might expect from a significantly weathered iron meteorite. 4) The composition given - high Ni coupled with moderately high Ga and Ge - is difficult to reconcile with a meteorite composition. Iron meteorites acquire high Ni concentrations through 1 of 3 mechanisms. Oxidation simply changes iron to FeO, leaving Ni behind. This can produce high-Ni irons with modest Ga and Ge. Nebular condensation can also produce high-Ni iron which then melts to form cores in which high-Ni iron meteorites form. This process, however, occurs at high temperature where the volatile elements Ga and Ge are depleted. Finally, you can produce high Ni through fractional crystallization. Ni prefers the solid phase when a core crystallizes, so early irons are low in Ni and later crystallizing ones are high in Ni. However, Ga and Ge behave opposite of Ni, so low Ni irons are high in Ga and Ge and high Ni irons are low and Ga and Ge. The published Ga and Ge values are at least a factor of 15 higher than reported for similar iron meteorites. 5) The holes exposed in the center of the specimen are not the shape one would expect of weathering, but seem circular. Circular vugs are commonly produced in slags when gases try to escape. There was more...including the fact that Indonesia is a nickel-rich locality as well as Tim's conclusion that Lovina was most likely a highly weathered example of a smelted Ni-rich sulfide. Sales have been suspended and monies are in the process of being returned. Further testing will be done to confirm Lovina's place of origin and the results will be posted to the list by mid-January.

Re: [meteorite-list] meteorite images..
That's actually a good question Mark, and you are certainly not alone with that request. My first choice for public domain photos of Meteorites would be NASA's photo archive. If you haven't checked it yet I highly recommend a visit: http://nix.larc.nasa.gov/search;jsessionid=393vi7bno140l And as Eric pointed out, there are a number of licensed but cost free photo galleries on the web, for example the Wiki-commons collection on meteorites. Beautiful pictures there, and I am sure it doesn't hurt to mention the source when using them for outreach purposes: http://commons.wikimedia.org/wiki/Meteorite Then there is of course the Encyclopedia of Meteorites which is expertly administered by Sergey Vasiliev and the IMCA and which offers a broad selection of user generated content including many good meteorite photographs. You'll have noticed these pictures when accessing the Meteoritical Bulletin's data base. Though not public domain the archive is at least a good starting point when looking for photos of particular specimens. http://www.encyclopedia-of-meteorites.com/ Michael Johnsons invaluable Rocks from Space Calender with hundreds if not thousands of meteorite photos completes the inventory. As the authors of the photos are usually represented with their contact addresses its easy to approach them and request the use of the respective image you might want to use: http://www.rocksfromspace.org/calendar.html Last but not least there are a number of very talented meteorite photographers around, Geoff Notkin comes to my mind, Tomasz Jakubowski, Mike Bandli, Phillipe Thomas, Andi Gren (etched irons!), Martin Horejsi (particularly rare locations), Michael Johnson (when it comes to premium Sikhote Alins), Jason Utas (who maintains a great photo collection on Flickr), Peter Marmet (with a beautiful photo collection of historic European specimens) and many other skilled photographers, to whom I apologize for not being able to mention them all. I am convinced all these folks will be most helpful if you contact them with a photo request for particular specimens. The same goes for myself, my photo archive is open to everyone's request and it's always been a pleasure for me to contribute photos to book-, website, or outreach projects, just drop me a note if interested. Producing these photos and maintaining an image archive of high-res data is cost- and time-intensive, so giving proper credits hurts no one and is commonly self evident.

[meteorite-list] Gauteng: State declares ownership before meteorite is found
One really wonders if this approach offers sufficcient incentive to initiate recovery efforts: Eyewittness News: Meteor belongs to the state Gia Nicolaides The Astronomical Society of South Africa said on Wednesday a meteor had no monetary value and belonged to the state where it landed. Dozens of people claimed the meteor spotted over Gauteng at the weekend landed on their property. The astronomical society's Tim Cooper said even if it landed on someone's property, they did not own it. By law in this country any meteorite which hits the ground belongs to the state. So it will be given over to the universities to study its origins and its characteristics, after that it will become property of the state so somebody who finds this object will not be able top keep it, said Cooper. The fireball lit up the skies and was seen travelling from Johannesburg to the north of Pretoria at about 11pm on Saturday. As yet no one has found the rock.

[meteorite-list] Meteorite - new issue - Lovina ungrouped iron
Today the current issue of Meteorite arrived. While I haven't found time yet to read through the articles, I had a post card fell from inbetween pages, showing a brilliant and most exciting photo, which I'd like to point your kind attention to. The photo shows the surf-sculpted mass of the Lovina ungrouped iron, a 1981 find from Bali Indonesia of a 8.2 kg meteoritic iron. Ever since I heard from its discovery and classification I wondered how it might look like. Particularly as I walked the very beach where it was found repeatedly in 2004 and 2008. Well, it is not exxagerated to say, that the specimen's appearance has nothing in common with iron meteorites as we know them. The anthrazite colored mass displays a beautiful and striking three dimensional crystallization pattern which reminds one on the stepped roof architectures of Balinese temples - or on colonies of polyhedral Pacific barnacles clinging to rocks in the surf. The iron is of such striking plasticity that one is tempted to doubt, that the structures present are indeed revealed by nature and not by a very gifted sculptor. Perhaps our fellow list member and author of this world class photo, Darryl Pitt, is so kind to provide a link. For those who might not receive Meteorite, or think, they have seen it all its really worth a look.

Re: [meteorite-list] Clarification.. Was Fusion Crust on Irons
Elton, Could you please name the significant source you refer to by presuming that the term fusion crust is only valid when describing crusts made up of glass/silicate components? I'm asking because the discussion so far did not provide any intelligent reason why this should make any sense at all. Perhaps it would be a good idea to start from there. Svend www.meteorite-recon.com MEM mstrema...@yahoo.com hat am 20. November 2009 um 06:08 geschrieben: Again Yahoo is near comatose and I am not getting all the posts. We are going to eventually see a predominately iron meteorite which is going to have a legitimate fusion crust (meeting the definition). When I said non -silicate bearing I meant insignificant silicate content and was trying to establish and end point for a series, mineralogically and metaphorically speaking--otherwise... as has happened here time and time again, people start throwing in exceptions and progress stops. (e.g. Campo was non-silicate bearing until someone found a silicated batch). Discussion is complicated by the lack of adequate definitions/ descriptions. They abound especially in a rare commodity. For another vexing example of undefined: how many atoms of copper, gold or lead need be in a glob in a meteorite to legitimately say that a meteorite has native Cu, Au, or PB? Every meteorite has an C,A,P atom so or per billion but where do we draw the line on declaring it? So you all know where I am going with this: I would like to see a new list of terms used in our field which ensures we are discussing the same thing/feature observed on multiple meteorites. I think many agree that as the term fusion crust is now defined and how it is actually used to refer to every eventual possible appearance-- even on rusty iron shale( yes someone has offered fusion crusted iron shale before) and fusion crusted paleo meteorites-- are very different things and that we need a better convention of what is and or is not the result of flight and how it relates to surface features in general on all types of meteorites. Suprisingly, very little science has been focused on the formation and features of fusion crust especially compared to the internal content. Even less effort has been directed are promoting operational terms to describe what is observed on different surfaces. Personal business has taken me far from the list for several weeks so if I haven't addressed your message please feel free to resend. I may not be active on the beloved list but I am getting some lab work done and hope to announce some really neat things next year. Happy Thanksgiving for those that celebrate the season...

Re: [meteorite-list] question on using a macro flash ring for photgraphing meteorites
Hi Glenn, others, You may try working with full spectrum daylight lamps. They emit a spectrum very similar to natural sunlight. By using two, or even better three lamps, you will be able to avoid hard cast shadows. In combination with dimmers you may simulate every daylight situation experienced outdoors.Anything starting from 20W will serve your purpose. The color spectrum your camera reproduces will be very close to what the human eye perceives under daylight conditions.

Mexicodoug wrote: Also the clear error that it states that the measurements were taken in December - January 2006 should be updated to January 2007, if in fact that is the date. It would seem they received that typo from Svend whose website says the same=2 0thing at the moment, on page 5 of his superb article when discussing the support between the two different fall dates (4 days apart): This is not the case. In my report I simply quoted the information received through the classifying institute. Of course the lab submitted their data directly to the editors in charge and not through me. So concerning this point the Bulletin and my report share the same sources but do not depend on each other.As you may see, the passage in question was set in quotation marks in my article because I quoted the author's words. I also named the author to make it clear that I am not the originator of the dates given for the measurements. The text says December-January 2006 and I totally agree with you it should better read December-January 2006[-2007], however, December 2006 for the time of the radionuclide measurements makes perfect sense to me. As far as the fall date is concerned, that indeed is a tricky question. This is what I can contribute: For the very first find of Bassikounou that became public, the 3 kg El Moichine mass, October 12 was reported by the owner of that mass. However this particular meteorite had already changed hands several times and so had the information assigned to it. To my knowledge this particular date, October 12, was then forwarded to the classifying institute together with the classification sample by the owner of that mass. A process I was not involved in. When Matthias and I started our research we had not much more to rely on but this date and the information from the owner of the first mass. It was not even known by that time that Bassikounou was a multiple fall. That is why we used the October 12 date in the early correspondence on the fall too. However in the course of our work it turned out that most eye witnesses as well as the local media reports gave of October 16 as the fall date. Accordingly we corrected the date in our papers and subsequently in the online version of our report. We also forwarded these findings together with the article in Horizons to the researchers in charge. Public and private research has chronologically overlapped in the case of the publication of the Bassikounou fall in the Meteoritical Bulletin. Thus it is regrettable and at the same time totally comprehensible that a variation occurs. I am convinced that the issue will be thorroughly cleared by the author's of the submission text once they are noticed of the discrepancy by the editor in charge. Contrary to any peer- and committee-reviewed system a private online editor has the invaluable vantage that he is able to react quite promptly to emerging new facts. Besides my own website describes just a hand full of falls which makes it quite easy to keep track of new evidence. And because I am just a one man show not even all of the corrections kindly forwarded to me make it online in time. The Meteoritical Bulletin data base however deals with ten thousand entries which are constantly reviewed under very high standard. An incredible ammount of time and effort is put into it by the editors to maintain these standards. The Bulletin's data base has achieved a quality that is hardly matched by any other public access databases in comparable fields. One has to admit this before pointing to obvious errors.

The specimen is aconic shield with a stub apex. It shows countless flow lines and impressively displays the ablation process of the atmospheric flight frozen in time. The surface texture represents the moment as the crust cooled during the transition from hot and bright to the cool and dark phase of the meteorite's flight. You may have to wait a while before you see a similar piece offered. Here is the auction link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=200384411749ssPageName=STRK:MESELX:IT For those focussing on large sculpted irons there is an impressive and fully regmaglypted 4.9 kg Sikhote Alin up for sale. The specimen's surface is dented with large elongated regmaglypts, several regions show much smaller but deeper regmaglypts. The meteorite shows a plethora of melt features such as flow lines, melt rims and rollover lips. It is heavily ablated and fully fusion crusted. This is a true museum specimen.And the best is, this striking display piece is still well below 50 Cents per gram. Folks, if I would not be selling this piece I would instantly buy it. I apologize for the bulky link: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=200384713860ru=http%3A%2F%2Fshop.ebay.com%3A80%2F%3F_from%3DR40%26_trksid%3Dm38%26_nkw%3D200384713860%26_fvi%3D1_rdc=1 Other witnessed falls up for sale include a72 g eucrite with glossy fusion crust, a 56 g Allende individual, a 33g Benguerir, a rare La Criolla, a 73 g Juancheng with beautifual fusion texture, a 62 g Kilabo (witnessed fall from Nigeria).

When I uploaded these specimens together with a couple of others on ebay I was met a wave of support and encouragements. Many of you didn't hesitate to placed bids and I recognized quite a number of familar ebay identities. To those that bid: Thank you all for your support and encouragement, your efforts are much appreciated. To all others interested, the auctions are running and those who are familar with my collection focus are aware that these specimens were selected with a keen eye for special morphologies. There is a large and exceptionally sculpted Sikhote Alin of 4.9 kg that is worth to take a look at, even if you do not intend a purchase. Another premium specimen is a heavily oriented L5 chondrite of 738 g with stunning radial flow lines. That one is a true textbook example of characteristic orientation features. Those of you who went out meteorite prospecting in the field will know that only one among a thousand meteorites you may find displays such dramatic orientation. Other specimens offered include Kilabo, Benguerir, a 73g Juancheng, a 56g Allende and La Criolla. You'll find all auctions here: http://shop.ebay.com/werffroenne/m.html?_nkw=_armrs=1_from=_ipg= and perhaps you've been looking for an old school NASA type meteorite scale cube? This one is among the last from our recent production series: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=200384401841ssPageName=STRK:MESELX:IT Thanks for your patience and your interest.
