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. I've been achieving acceptable results with a set of four daylight lamps and wouldn't want to miss them: http://www.meteorite-recon.com/en/Meteoritensammlung.htm Cheers Svend www.meteorite-recon.com Glenn Skinner lostbow...@gmail.com hat am 13.

Papers were published arguing that evidence of extraterrestrial impact, including fullerenes containing extraterrestrial 3He, are found at the Permian - Triassic boundary. Later researchers, who restudied various Permian - Triassic boundary outcrops, including the ones studied by Becker, and were unable to replicate their findings. The evidence used to argue for Bedout High being an impact structure either could not be replicate or turned out to be open to alternative interpretations. Finally, there is a considerable amount of controversy whether many of the fullerenes found in sediments are even of extraterrestrial origin.

Hi André, I guess, you have to delete Argentina from your list. I'm not fully sure about, but due to the new legislation, where Argentinean meteorites are handled like artefacts, they aren't allowed to be exported anymore. It is hard for the Argentinean curators and scientists, but I fear, they will have to do without meteorites as consequence of the new law. Or better to say, from now on, they rather have to purchase new material, because the most cost-effective way, the swapping and trading is now blocked. Even if there shall be a possibility to acquire special permits (?), I doubt, that anyone of the main suppliers of important meteorites, not to mention the private collectors, would be willing to occupy himself with all that paperwork. I think this was also the main reason, why so few only gave meteorites on loan to Andrzej's exhibition - cause with the new Polish export prohibition, they weren't sure, whether they would get their pieces back or feared the red tape.

[meteorite-list] Fear of impacts, bad techniques, Morrison, Mars Nuts, lack of money
Hi Darren, Paul - On yeah, and the KT comet impact did not kill the dinosaurs. Keller told us all about it, and it was repeated again and again and again. Well, let's see: People naturally want to deny that recent impacts have taken place. Provide them with any flimsy way of denying it, and they'll do it. We have a well funded and well supported opposition; my side has no money and no means of communication since Dr. Peiser took the Cambridge Conference over to global warming scepticism. Gosh gee thanks, Benny. NASA still run by Mars Nuts who want to spend a hundred billion or so to fly a few men to Mars, and leftovers from the 1950's and 1960's who want them to do it. So they're in a state of denial as well, particularly as to comet impact rates, thanks largely to Morrison. Me, I've had a stroke. But the peoples remembered these impacts, even if they did not use modern terms like asteroid and comet to describe them: http://forum.palanth.com/index.php/topic,1093.0.html Also: http://forum.palanth.com/index.php?topic=1077.msg3266 No one has looked at the Kiscoty structure yet, and we're still waiting for the cores from the Carolina's.

Re: [meteorite-list] Southern America museuns meteorite trades
Hi Martin Campo del Cielo is a special case. There is a provincial law from 1970 that protect all the meteorites from Chaco province. Although some part of the Campo del Cielo strewnfield (about 5%) is in Santiago del Estero province, when you get to customs you have to prove that they were collected in Santiago province before December 2008, or in Chaco province before 1970 something really hard to do. Only the very old Campo specimens already exported before 1970 are OK. About pre-dated new finds, well there is always the chance that you can be caught in the lie. Not exactly a pre-dated, but think in Berduc. Some started to sell them as Arroyo Malo and were disacredited as soon as it was published. I guess a lot of people loose money there as now they can't legally resell them and have in hands illegally exported Berduc meteorites. There are a few Argentine meteorites actually under analysis, really collected before the law (actually their analysis started before Dec. 2008) but any new old find is questionable. On the other hand, a newly found La Criolla specimen can be easily be passed as an old one from that fall. Unless somebody catch the hunter at the moment of find it is hard to prove it was not found 5 or 10 years ago.

[meteorite-list] Holocene Start Impacts
Hi - I need more money and less cr*p from some people: 2009 FALL AGU San Francisco, CA Field-Analytical approach of land-sea records for elucidating the Younger Dryas Boundary syndrome SECTION/FOCUS GROUP: Paleoceanography and Paleoclimatology (PP) SESSION: Younger Dryas Boundary: Extraterrestrial Impact or Not? (PP15) AUTHORS (FIRST NAME, LAST NAME): Thierry Ge1, MARIE-AGNES MICHELE COURTY2, Francois Guichard3 INSTITUTIONS (ALL): 1. Geoarcheology, INRAP, Pessac, France. 2. Prehistory -IPHES-ICREA, CNRS-MNHN, Tarragona, Spain. 3. Paleoocenography, CNRS-CEA UVSQ, Gif-sur-Yvette, France. Linking lonsdaleite crystals, carbon spherules and diamond polymorphs from the North American dark layers at 12.9 cal yr B.P. to a cosmic event has questioned the nature and timing of the related impact processes. A global signal should trace the invoked airshocks and/or surface impacts from a swarm of comets or carbonaceous chondrites. Here we report on the contextual analytical study of debris fall events from three reference sequences of the Younger Dyras period (11-13 ka cal BP): (1) sand dune fields along the French Atlantic coast at the Audenge site; (2) A 10 m record of detrital/bioorganic accumulation in the southern basin of the Caspian Sea with regular sedimentation rate (0.1 to 3 mm per year) from 14 to 2-ka BP cal; (3) the Paijan sequence (Peruvian coastal desert) offering fossiliferous fluvial layers with the last large mammals and aquatic fauna at 13 ka BP sealed by abiotic sand dunes. The three sequences display one remarkable layer of exogenous air-transported microdebris that is part of a complex time series of recurrent fine dust/wildfire events. The sharp debris-rich microfacies and its association to ashes derived from calcination of the local vegetation suggest instantaneous deposition synchronous to a high intensity wildfire. The debris assemblage comprises microtektite-like glassy spherules, partly devitrified glass shards, unmelted to partly melted sedimentary and igneous clasts, terrestrial native metals, and carbonaceous components. The later occur as grape-clustered polymers, vitrified graphitic carbon, amorphous carbon spherules with a honeycomb pattern, and green carbon fibres with recrystallized quartz and metal blebs. Evidence for high temperature formation from a heterogeneous melt with solid debris and volatile components derived from carbonaceous precursors supports an impact origin from an ejecta plume. The association of debris deposition to total firing would trace a high energy airburst with surface effects of the fireball. In contrast, microfacies and debris composition of the recurrent fine dust/wildfire events would trace a series of a low energy airburst. Their record is expressed in the Audenge sequence by a series of water-laid laminae of charred pine residues formed of carbonaceous spherules wrapped by carbonaceous polymers that includes lonsdaleite crystals as detected by high resolution in situ micro-Raman analysis. This association suggests recurrent flash forest wildfires ignited by hot spray of carbon-rich debris, followed by heavy snow falls. The record from the Peruvian desert suggests a possible linkage between the repeated debris fall/wildfires during the Younger Dryas and the following irreversible aridity along the Peruvian cost. In contrast the Caspian record of the Younger Dryas period indicates more gradual changes, possibly buffered by the hydrological functioning of the Caspian sea in a complex region. The Audenge context offers the amplified signal needed to understand at local to global scales the spatio-temporal pattern of impact-airburst events.

[meteorite-list] Where the ETs are hiding
Hopefully, they aren't wild things. http://www.scientificamerican.com/blog/post.cfm?id=what-do-we-really-know-about-the-ku-2009-10-13 What do we really know about the Kuiper Belt? Fifth dispatch from the annual planets meeting By George Musser FAJARDO, Puerto RicoIt smacked of a cunning plan. The organizers of last week's planets conference put one of the best talks in the very last session of the very last day. Most scientists had either left for the airport or the beach. I almost didn't make it myselfthe room and time got switched at the last minute. If the speaker, Wesley Fraser of the California Institute of Technology, is right, planetary scientists are going to have to rethink the Kuiper Beltthe vast band of smallish planets that orbit beyond Neptune. Using the Hubble Space Telescope, Fraser and his colleague Mike Brown observed one of the largest of these objects, Quaoar, and its little moonlet, Weywoot, to refine estimates of its size and mass. They found that Quaoar is smaller than previously thought, only 900 kilometers in diameter. Consequently, it must be denserabout four grams per cubic centimeter. This makes it by far the densest Kuiper Belt object (KBO). It outdoes even a fairly dense asteroid such as Vesta. Planetary scientists typically explain dense KBOs by imagining that they started off larger and less dense; they then collided with one another, stripping off lighter material such as ice and leaving behind mostly rock. Yet by the new estimate Quaoar is denser even than rock, so even completely stripping its ice wouldn't be enough. Moreover, astronomers detect ice on its surface. It makes no sense. It's confusing, to say the least, Fraser says. That's only half of it. Most KBO moonlets have circular orbits. That is thought to be a consequence of coalescing from collisional debris: debris rings naturally settle into a circular shape. Yet Weywoot's orbit is distinctly oblong. We have to completely rewrite the book, Fraser concludes. One radical idea is that Quaoar is a refugee from the asteroid belt between Mars and Jupiter. Asteroids tend to be denser than KBOs, and Jupiter might conceivably flick one to the farthest reaches of the solar system. But the hapless exile would tend to wind up on a highly elliptical orbit around the sun, whereas Quaoar's orbit is nearly circular. Erik Asphaug of the University of California, Santa Cruz, offered another explanation based on work he presented earlier in the week. Perhaps Quaoar collided with a much bigger bodysomething approaching the proportions of Mars. Like a Mini blindsided by a Hummer, Quaoar would have gotten seriously banged up by such a collision, maybe enough to give it an anomalously high density. If so, Quaoar might be living proof that substantial planets used to orbit in the distant solar system and may still lurk out there. Clearly this is one of those more data are needed situations, and Fraser has applied for additional telescope time. One thing is sure, though. People typically call KBOs icy bodies, like giant comets. But they can also be rocky, like small Earths. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Scientists think a fireball that flew over New Mexico may have been close
enough to actually hit the ground.
A Santa Fe
astronomer was able to catch the fiery streak on video. Thomas Ashcraft
says the fireball didn't disintegrate when it hit the atmosphere. It
may have landed somewhere near Taos.
If we can get other camera angles, than we can put all the
positions together and possibly hunt for an important--scientifically
important--meteorite, he said.
The event was also captured by cameras at Sandia National Labs.
Scientists estimate the meteor was about the size of a basketball all
the way up to that of a small car.
Scientists at Sandia think it disintegrated over Chaco Canyon.

[meteorite-list] Meteor over The Netherlands
Dear List, And an other one. A large meteor has been seen, Oct. 13th at about 19:00h local time, over The Netherlands: http://twitgoo.com/42p74 Numerous fireball sightings have been reported from all over The Netherlands. Mostly reported direction is West-to-East. Most reports speak of a splitting in three pieces. From (mainly) the North of our country, there are also reports of sonic booms and pieces seen falling down. Living in the North of The Netherlands, I however saw nothing, heard nothing :-( Best regards, Rob Lenssen The Netherlands __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
