Re: [meteorite-list] Exogenic Fulgurites
Hello Norm, I have some of this material. It is was't especially cheap but not unaffordable. I came upon it 5 years ago from the finder/co-colector(?). It is a beautiful curiosity but I was given a different origin story. According to the finder, this came from totally encased voids in Pliocene ( or later) lava flows where a low-viscosity, fast-flowing lava encased standing timber. While most all trace of the timber was burned away, there were minor amounts of charcoal recovered. The drippings are a higher quality glass that show flow. Owing to their long fragile lengths and pristine surfaces, they had to drip slowly and intermittenly into a sheltered void to avoid weathering. I presume these flows dribbled into the chamber over some time period as some stalactite-stalagmite like forms were observed in some of the samples. As I recall there were some branch like cavities uncovered. Each had these glass gardens. In fact they looked a lot like classic cave formations but o evaporation was involved in their growth. They are attractive in any event but, too many differences from fulgurites. The forms are too smooth, too perfect a surface for a quick lightening flash heating. These were hot for a longer time. Some were green to yellow and remind me of Hawaiian lava tube formations , iridescent in some etc. Given the cavity shapes, charcoal fragments and long fragile Pele tear-type shapes I favor the lava flow theory of origin. Regards, Elton Norm Lehrman wrote: List, A guy came in today with a flat of shiny black glass that looks identical to Wabar or Irghizite impactites.

Re: [meteorite-list] Re: Sikhote Question, Impact Pits, Oriented Campo
Actually, Geoff-- ALL parts start out as shrapnel shapes once disruption began: when deceleration stresses sheered the meteor body(s) apart from front to rear. We know from eye witnesses that there were several explosive disruptions(8+) and at each disruption there were more shrapnel surfaces exposed to ablation. The parts that we treasure are those that had enough velocity to go through ablation and regmglypthing, etc. I surmise that those sharing both characteristics of smoothies and shrapnel were those that ran out of speed towards the end of incandescent flight and ablation ceased to sculpt them. As to impact pits, these are a bit harder to explain. One thought is that the larger surfaces-- with more air resistance, were slowing faster than smaller bodies that entered the sheltered slip stream of the larger and caught up to them with still enough energy as a bullet. Even this theory likely doesn't account for all the physics. If someone knows the Rockwell grade of SA, given the diameter of the pit, one might be able to compute the relative size of the impactor plus energy involved gouging the pit. it might give insight in how the pits were formed. Regards, Elton Notkin wrote: When I started collecting Sikhotes seven or eight years ago, I was under the impression that all individuals had come through the atmosphere on their own, and all shrapnel pieces were the result of explosive fragmentation around the craters (this view supported, I believe, by the fact that only shrapnel is found in the craters?). Over time, I've seen a few pieces that exhibit characteristics of both individuals *and* shrapnel, and I'm sure some of you have too. An example would be, say, a ~1kg otherwise completely regmaglypted individual that has one sheared, shrapnel-like face. I expect this is the result of a larger individual fragmenting in the air shortly before impact. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Coming in late... I've not heard of Molybdenite in massive veins like this as it forms in metamorphosed sea deposits--aka Marbles in small hexagonal clusters of flat soft malleable crystals. While it shares a 1 in hardness with graphite it is harder than graphite but will still leave a streak. It superficially resembles silicon of the type manufactured for industry which I don't know the hardness of but it doesn't streak. I am inclined to go with Molybdenum(sp) but something from a refining/refractory/smelting operation...aka man-made. TRIVIA: Incidentally the name comes from the Greek: molybdos meaning lead. However the Latin for lead is plumbdum hence the symbol of Pb and the career field plumber because the Roman's used lead pipes to deliver water to houses. Both Greek and Roman languages come from the same root referring to the color of lead as in lead-gray which is really a silver gray on a fresh surface. We call it the lead of a pencil lead when it is really graphite but once was lead bars used to write on slate/marble slabs, however English Lead derives from the Celtic Loud for Red from the color of lead oxide-- and you wonder why mineral names are so difficult to decypher.

Re: [meteorite-list] 26-AL isotope counting
Hello List and Larry, Since no one else has shouldered the question I'll try to comment. You asked several questions and made several observations. In regards to those, Aluminum26(Al26) is not a test for meteorites, per se. There is no single test that I am aware of for making a determination if a sample is meteoritic. The paucity or abundance of cosmic ray tracks, Carbon 14, Al26 all go to determine that a sample has or has not gone through a period of space transit. Al26 analysis was one of several tests on Shirokovsky to reach a preponderance of evidence. Because similar terms/concepts are used in different situations while analyzing AL26 , I've broken some of them out as follows: CASE 1: Al26 which was present in the solar nebula has long since decayed to Magnesium26(Mg26). Finding a Mg atom in a molecule within a crystal matrix where an Al atom should be, shows that the crystal hasn't been reset since the formation of the solar system. CASE 1A: If the clock has been reset via differentiation of the parent body/ impact melting, etc. The ratio of Mg24 to Mg26 might be used to estimate the petrographic age of a sample by comparing what the ratio would be between the original/cosmic abundance of Al26 and the present quantity of the Al26 daughter product(Mg26).(see the McSween Quote for contrast) CASE 2: Al26 is replenished by cosmic rays/irradiation. Exposure can convert Phosphorus (P26) or Silicon (Si26) into Al26 even on earth. However the ratios of Al26 from a terrestrial vs non terrestrial sample are very large. So a sample having a certain BUT low overall Al27/Al26 ratio could indicate a long or a short terrestrial exposure but still very far from the levels that would be formed during unshielded space exposure. This could be one of the terrestrial exposure tests used in lieu of C14 and others if the terrestrial age is over than 50-60 K years. CASE 2A: Like case 1 above, finding an Al26 atom in a SiO2 (silica) Xtal matrix for example, is evidence of recent cosmic ray exposure/irradiation. This is being used to date certain terrestrial events such as more precise dating of glaciation coverage. ' CAVEAT: The size/diameter of the meteoroid affects the distribution of replenished radionucleides With more being found in the outer portions than those portions from the interior.(shielding) That is a whole treatise in itself. Stating that Shirokovskys' low levels of Al26 is an absolute fool proof test might be true but oversimplified. As I recall, Larry Taylor's research showed that the AL26 levels fell within the terrestrial ratio band. There is probably a technical reason that the presence of AL26 makes calculating the Mg24/Mg26 ratio impractical such as nearly identical X-ray diffraction patterns. From the quotation it is unclear if the writer meant the current or primordial existence of Al26. Your question on Allende, I assume is rhetorical. Of course it is a meteorite Al26 analysis or not. There are lots of other characteristics used to identify meteorites. See the Caveat above, however, I would think that some Al26 should have been found in all the research that has been conducted on Allende. I don't understand Hap McSween's quote on Vesta and the absence of Mg26 out of context. Taken as it is it doesn't seem accurate to me either. I hope this was at least another look at your observations with out confusing folks more than we already were. Not by your post but by the complexity of it all. I agree that on casual review, there seems to be some conflicts/inconsistencies. Regards, Elton [EMAIL PROTECTED] wrote: Greetings List, I have a technical question / observation I'd like to discuss with some of you knowledgeabe in the area of isotopic counting, particularly 26-AL.

The recent issue with Shirokovsky brought this subject back to the surface for me. Don't get me wrong, this is not about Shirokovskys' pseudo-meteorite status, that rock is apparently not a meteorite for many reasons. It is about the comments made in response to this stones cosmic exposure test, that it has not experienced any time in space, based on 26-AL counting, asserting that this test is an absolute fool proof determinator. I have read in several publications, information that seems to contradict that reasoning. I have also spoken with several semi experts, (one author and a couple meteorcists) on the subject and opinions are not unanimous. Just recently a post from Ron Baalke discusses this, here is a snipet, pay particular attention to the last sentence; Like all radioactive isotopes, short-lived ones decay to another isotope.

Re: [meteorite-list] Volcano Bombs Impact Breccia Identification
To releave the suspense, there are NO occurrences of volcanos/volcanic geology in eastern North America since before the Triassic(200±mya).* The only volcanic stems left today in the Eastern North American plate are a part of a plutonic and volcanic series in New England (Devonian 345 ±mya). All were along the margins of the eastern seaboard. There are about 9 crypto-volcanic structures in the central US that have been identified as astroblemes. After the Cretaceous(65 mya) volcanos flourished in the western US. As to the natural occurrence of volcanic material on the Wisconsin and Michigan Peninsulas. Not unless it was imported for barbecues! I've never seen a brecciated volcanic bomb and I don't think it exists by definition. (Note Mark's post on magmas and xenoliths even if he did not call them that) There is more smelting slag in the Great Lakes area than another place I know of. It was used to pave roads, build railroad ballast, even dumped into the lakes. ( Anyone remember the emerald material left by aliens recovered on the lake floor some guy was selling on the internet?) Impact breccia could, in theory, have been transported from any of several craters on the Canadian Shield.--by glaciers or as a part of some smelting ore transport. NON impact related Breccia lenses can occasionally be found along contact faces of faults and are occasionally brought to surface in mining operations. Impact breccias look like melts or rocks that have been roasted. Other breccias likely to be found near you are more likely to have a limestone/calcium content..which will effervesce in hydrochloric acid. They will most likely contain clasts which look sedimentary. I hope this helps to exclude volcanic bombs as a source...

I subscribe to them and I never see you posting on those lists designated for sales/trades..DUH. 4) refrain from posting a specific trade more than ONCE? 5) Please tell us how why so quickly tire of your acquisitions? You seem to beg for a given meteorite one week then be in urgent need of getting rid of them the next...Have you considered renting? Elton STEVE ARNOLD wrote: I have upped the anny(sic) on this one.
