[meteorite-list] Scientists Preuse Unearthed Cores From Ancient Chesapeake Bay Crater
http://www.timesdispatch.com/servlet/Satellite?pagename=RTD%2FMGArticle%2FRTD_BasicArticle%09s=1045855935235c=MGArticlecid=1137834861822path=!health!healthology Scientists peruse unearthed cores from ancient Chesapeake Bay crater Dozens from around the world converge on N.Va. for samples BY A.J. HOSTETLER RICHMOND TIMES-DISPATCH (Virginia) March 22, 2006 RESTON -- In a former federal printing plant, Belgium geologist Philippe Claeys hovered over the tables of rocks, some 600 million years old, hoping to find traces of an asteroid. Claeys was among dozens of scientists from around the globe descending on the U.S. Geological Survey this week to select samples of a 1.1-mile-long core, much of it granite, unearthed last fall from the ancient crater under the Chesapeake Bay. He and about two dozen other scientists from Finland, Austria, Germany, Estonia and elsewhere strolled Monday through the one-time printing plant filled with open boxes of cores. In an atmosphere of a silent auction, they wrote their names on slips of clear Mylar and tucked them beside the desired rocks for project officials to sort through and distribute later. They were drawn to the USGS headquarters by the remains of what geologists say was a fiery, 2-mile-wide space rock that blasted into coastal Virginia more than 35 million years ago, carving a hole that quickly filled with tons of water, rubble and debris. The only thing you could do to simulate the conditions of the impact is a nuclear blast, said Greg Gohn, the USGS project leader. Claeys, from the Free University of Brussels, wants to identify the cause of the crater without setting off a nuclear explosion. He suspects that the bay was a bystander to a major collision in the asteroid belt between Mars and Jupiter. Debris from that collision, he says, might have bombarded the Earth not just in the Chesapeake Bay but in Siberia, Canada and possibly other sites where craters from about the same time frame have been found. What we have so far is pointing to an asteroid, he said. He plans to study the ratio of platinum-related elements, a telltale sign of a meteorite, in the Virginia cores. Comparing that with the ratio found in other craters of the same age could nail the culprit here in Virginia. Something that happens in the asteroid belt, between Mars and Jupiter, can, in a short geologic time frame . . . send a whole bunch of large projectiles towards Earth, he said. That's a little bit scary. We don't know when that's going to happen again. Two of the crater project's principal investigators, Uwe Reimold of Germany's Humboldt University and Christian Koeberl of the University of Vienna, worked side by side, conferring over the samples. Moving slowly from table to table, they scrutinized the mostly gray and tan rock for samples to investigate the physical processes involved in creating impact craters and how the rock was altered chemically. Koeberl said he was convinced that new data from a much younger and well-preserved crater in Ghana would help them interpret the crater centered on Virginia's Eastern Shore. They left a long trail of Mylar slips. Each scientist was limited to 150 requests. Both assisted in the drilling last fall, which ran nearly continuously in Northampton County near Cheriton for almost three months to remove 5,795 feet of cores. The USGS paired with the International Continental Scientific Drilling Program and NASA on the nearly $1.5 million project to dig into the basement of the 53-mile-wide crater. The crater's epicenter is Cape Charles. Scientists expect the cores to reveal more about the effects the prehistoric impact had on the region's geology and water supply and to help better estimate the space rock's speed, size and energy as it slammed into the seabed. Other scientists will study samples of ancient water found in the cores that had been trapped in the crater's depths by the impact's aftermath. The crater is the largest of its kind in the U.S. and the seventh-largest in the world. It is 1,000 feet beneath the lower part of the bay, surrounding peninsulas and the intercontinental shelf of the Atlantic Ocean. The USGS plans to return this spring to the drill site to core the top 412 feet to complete the record. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Relic of Life in that Martian Meteorite? A Fresh Look (ALH84001)
http://www.eurekalert.org/pub_releases/2006-03/ci-rol032206.php Public release date: 22-Mar-2006 Contact: Marc Fries [EMAIL PROTECTED] 202-478-8993 Carnegie Institution Relic of life in that Martian meteorite? A fresh look Since the mid-1990s a great debate has raged over whether organic compounds and tiny globules of carbonate minerals imbedded in the Martian meteorite Allan Hills 84001 were processed by living creatures from the Red Planet. The materials have been under intense scrutiny ever since. Scientists at the Carnegie Institution's Geophysical Laboratory, with colleagues,1 have taken a fresh look at how material associated with carbonate globules was created using sophisticated instrumentation and they compared the results to analogous globules from a volcanic complex on Svalbard, an island north of Norway. It does not appear that living organisms were at work. The research is presented at NASA's Astrobiology Science Conference (AbSciCon) 2006 at the Ronald Reagan Building in Washington, D.C. March 26-30. See http://abscicon2006.arc.nasa.gov/ for details. To some, the tiny carbonate globules from the meteorite seem to resemble minerals that arise from microbial activity on Earth. The team focused on whether macromolecular carbon (MMC) in and around the globules was processed organically or not--an unresolved issue. The team had a complete depth profile of the meteorite. Lead author Andrew Steele explained, By using micro-Raman spectroscopy and a scanning electron microscope we could detect both the structure of the minerals and the forms of carbon present. We did a similar analysis on carbonate globules from Earth in terrain analogous to Mars--the Bockjord Volcanic Complex on Svalbard--for comparison. The researchers found that the macromolecular carbon is always associated with the mineral magnetite. This association is important because magnetite is known to act as a catalyst in the formation of MMC. Macromolecular carbon present within the carbonate globules in ALH84001 may represent the first evidence of non-biological synthesis of organic molecules on Mars. Although we haven't settled the debate on whether evidence of life is contained in Allan Hills, we have shown that these carbon complexes likely formed by non-biological processing on Mars, concluded Steele. ### Talk and poster schedule subject to change.

[meteorite-list] SMART-1 Images: Tectonic 'Wrinkles' in Crater De Gasparis
http://www.esa.int/SPECIALS/SMART-1/SEME93OVGJE_0.html Tectonic 'wrinkles' in Crater De Gasparis SMART-1 European Space Agency 22 March 2006 This image, taken by the Advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows Crater De Gasparis on the Moon. The AMIE camera obtained this image on 14 January 2006 from a distance of about 1090 kilometres with a ground resolution of approximately 100 metres per pixel. Crater De Gasparis is located close to the Mare Humorum, at longitude 51.2° West and latitude 26.0° South, on the lower left quarter of the Moon's Earth-facing side. It has a diameter of about 30 kilometres and can be seen with the naked eye from Earth. The criss-cross patterns in it are called rilles (these are features where the surface has sunk down to form a trench). These rilles coincide with deep tectonic faults that have been active over a long period of lunar geological evolution. They are the result of stresses due to all the tidal forces and volcanic expansion over the lunar mantle during the last stages of lava flooding of Oceanus Procellarum. The fact that the rilles cross the crater means that they formed after the crater. This is a good example for how geologists can determine the relative history of the Moon's surface. This crater is named after the Italian astronomer Annibale de Gasparis (1819-1892). De Gasparis was director of the observatory in Naples, Italy.

[meteorite-list] Could We Tell Life If We Saw It? (Recorded Lecture on ALH84001)
http://aics-research.com/lotw/ March 20, 2006 Could We Tell Life If We Saw It? ALH84001 in 2004 Joe Kirschvink California Institute of Technology 34 min. (requires QCShow Player) How can we hope to distinguish true biological microfossils from random assemblages of crystalline mineral material - especially if the life that those microfossils might represent were potentially an independent origin of life, billions of years ago, on another planet, and is now likely extinct? That's the question that has raged around the structures found in the Allen Hills 84001 meteorite. As UCLA's William Schopf has written, There are fine lines between what is known, guessed, and hoped for, and because science is done by real people these lines are sometimes crossed. But science is not a guessing game. The goal is to know. 'Possibly... perhaps... maybe' are not firm answers and feel-good solutions do not count. With regard to the famed Mars meteorite, for example, life either once existed on Mars or it didn't. Meteorite ALH84001 either holds telling evidence or it doesn't. Eventually, hard facts will sort it out. Schopf has been among the harshest critics of the earliest interpretations of life in ALH84001. Probably the best way to avoid being fooled by nonbiologic structures is to accept as bona fide fossils only those of fairly complex form. This may seem an unreasonably stringent rule for truly ancient fossils since the earliest kinds of cellular life (here and presumably elsewhere) almost certainly were very simple - probably individual, tiny, spheroidal cells. But until we have a sounder base of knowledge and better rules to separate nonfossils from true, it is best to err on the side of caution. CalTech's Joe Kirschvink agrees, but comes to a different conclusion. Microfossil paleontologies based on morphologies are undoubtedly flawed. In morphology's place however, Kirschvink compellingly argues that the fingerprint of natural selection can be detected by the very complexity and purity of the results that selection produces. While there are no biological processes that can not be reproduced in some manner by non-life processes, the results of simple inorganic syntheses are haphazard at best. Magnetite exists in ALH84001, and Kirschvink argues that it was biologically produced, primarily by subjecting it to a Venn diagram analysis of seven different physical characteristics, each ranging from hard to easy, and in the process pointing out that ALH84011's magnetite is of an even higher quality than is capable of currently being manufactured by human processes. Magnetotactic bacteria were discovered on Earth only in the 1960's, but we now know of south- and north-pole seeking bacteria. For an organism evolved to exist in ponds within a narrow range of oxic-anoxic conditions, where light doesn't penetrate and gravity is overwhelmed by random Brownian motions, the evolution of magnetotaxis is an exceptionally clever solution to the problem determining orientation. Although Mars no longer has either a magnetic field or liquid water, it is strongly presumed that Mars once had both, and the most parsimonious, simplest explanation for the high-quality magnetite crystals that appear in ALH84001 is that they were synthesized by organisms similar to terrestrial bacteria. - Wirt Atmar About the Speaker Joe Kirschvink is widely known as an original thinker and an excellent teacher. Among his major contributions are: # the idea that biogenic magnetite produced by the magnetotactic bacteria (magnetofossils) might be responsible for the magnetization of some sedimentary rocks; these magnetofossils now provide the strongest evidence for early life on the planet Mars. # A second idea was that the magnetic field sensitivity in animals might be due to small chains of the same biogenic magnetite functioning as specialized sensory organelles; this work has provided a solid biophysical basis for understanding magnetic effects on animal behavior, and has actually led to the discovery of these new sensory organs in higher animals. # An idea that is generating much interest recently is that the entire Earth may have actually frozen over several times in Earth history, resembling a Snowball, potentially causing some of the most severe crises in the history of life on Earth and perhaps stimulating evolution. # Another original concept is that the Cambrian Evolutionary explosion may have been precipitated in part by large burst of true polar wander, in which the Earth's rotational axis moved to the equator in a geologically short interval to of time, and... # that the burst of biomineralization observed in the fossil record at the Cambrian Explosion may have resulted from the evolutionary exaptation of the magnetite biomineralization system. A common thread in all of these efforts is the study of paleomagnetism and rock magnetism, for which the Kirschvink group maintains laboratories dedicated to the study of weakly magnetic
RE: [meteorite-list] Earth Rocks Could Have Taken Life to Titan(doubts)
Hi Sterling, As always a well presented response and a good crack at the theory!. Actually you may have something there, have you ever dropped a large rock into a shallow pond/pool? The suction of the water moving in to fill the void behind the rock pulls up debris from the pond bed and even propels it high into the air (scientifically known as 'a splash'! :), I guess this is actually a similar'ish' effect to what you are describing, only much more complex as plasma and air heating is involved, but there clearly is some sort of mechanism that could propel debris back up the flight path of a falling rock, - at least in water anyway.

Webb Sent: Tuesday, March 21, 2006 10:52 PM To: meteorite-list@meteoritecentral.com Cc: Mike Fowler Subject: Re: [meteorite-list] Earth Rocks Could Have Taken Life to Titan(doubts) Hi, List, Mike You've put your finger on many of the problems of getting a rock off a planet and launched into space. When it was first determined that Martian meteorites WERE Martian, there were choruses of no way! No impact model anticipates such ejection; none, even today, shows unequivocally how it could happen. And Mars, of course, is easy. Its gravity and escape velocity is much less than the Earth's and its atmosphere is much thinner. Still, the models do not predict it. In fact, they say still it's impossible. The problem is it happens. We got the rocks. They arrived here on Earth. So it MUST be possible. Naively, it seems that getting rocks knocked off the Moon to the Earth should be easy. It turns out it's easy to get them knocked off the Moon, but hard (for reasons of flight dynamics) to get them to the Earth. Mercury would seem to be a good source (no air, weak gravity) and Gladman's earlier simulations say we should have them here, but we don't seem to have any indisputable Mercurian meteorites. Venus has gravity almost as great as the Earth's and a much thicker atmosphere. Gladman's earlier simulations say there should be lots of Venusian meteorites getting to Earth, but again the museum cases are notoriously short of Venusian achondrites! The difficulty of getting a rock out of the Earth's atmosphere from an impact is much harder than you present it. When a stone enters the atmosphere at high velocity, it encounters the thinnest air first, allowing a gradual loss of velocity. But a stone leaving from the bottom of the atmosphere encounters the densest air at the first moment when it has the highest velocity. The chief problem is rapid ablation. This has been studied extensively in the problem of how tektites are produced and high velocity ejecta get vaporized in rapid ablation long before they get out of the atmosphere. The bigger and faster the rock, the worse the problem, and rocks will get burned away before they travel very far. Yet, we know it can happen; Mars proves that. Naturally, I have a theory... When an impactor enters the atmosphere, it creates a tunnel of rarefied air in its path by pushing the air out of the way. The heating of the atmosphere in that path helps to keep it from collapsing instantly. This is all true for even a small object, your ordinary meteor. The long rolling thunder after the explosion of a meteor that succeeds in getting down to the lowest levels of the atmosphere is the sound of air closing that rarefaction tunnel. When a large object which will become an impactor passes through the atmosphere, the rarefaction tunnel becomes much larger, with lower internal pressures, and persists much longer and extends for greater distances. It may effectively reach out of the atmosphere. Any piece of the target surface given a high enough velocity in the right direction could escape through the rarefaction tunnel without meeting enough resistance to destroy it. Aiding in the process is a plasma plume from the impact that blows back along the flight line, rarefying it even more and extending the duration of the tunnel. However, not very many impact-shocked rocks head in that direction! My theory is that a sufficiently large impactor (100's of meters) creates a much more efficient and powerful rarefaction tunnel than we usually imagine. First, there is a vast quantity of very high temp plasma created on the forward face of the re-entering object. I omit a long winded explanation of why it is that the plasma organizes as a series of toroidal rings surrounding the tunnel, but it does. When a current circles the surface of a torus transversely, it generates a circulating central current that keeps the torus from collapsing to smaller diameters and, if strong enough, may even expand it. As long as the currents flow, the tunnel remains open. You end up with a vacuum pipe extending from the surface of the Earth to the top of the atmosphere. A vast quantity of target materials, not from the point

The Meteorite Directory is for non-commercial meteorite links. All Meteorite Dealers can list their sites in our free Meteorite Dealer YellowPages. We are looking for a couple of volunteers to join our MeteoriteTimes team to help build up the number of links in the Meteorite Directory. Please reply to this email if you are interested in taking on this responsibility. http://www.meteoritetimes.com/ Thank you!

Hello All: Bright and sunny in Tucson today. You should all come back -- we'll do another Gem Show. But seriously, would somebody please be kind enough to send me David Gregory's email address . . . or, David, if you see this, please email me off-List. Sorry to use the List for a personal request.

[meteorite-list] Tucson Thank You Brenham Info
Hello List, While this is coming a little late, I wanted to take the opportunity to thank everyone that came to visit us in our room at the Inn Suites, our booth at the Main Tucson Gem and Mineral Show, and the Meteor Mayhem Birthday Bash. It turned out to be an amazing show for my family (attending for the first time this year) and for me. A very special Thank You needs to be extended to all of you on this list that participated in the positive support and vote that Phil and I should receive a special Peoples Choice Harvey Award. While the secret was out as soon as Greg's initial post hit this list, and the replies started coming in, it was still a great honor to receive. Geoff Notkin and I thought it would be cool several years ago to start giving out awards at our party for a couple of reasons. The party is a great venue for giving the awards since so many people in the Meteorite Community gather in Tucson each year. Geoff and I realized early on that we really do have an amazing group of men and women in our field of collecting. It only seemed fit that someone attempt to recognize these people and their great accomplishments. And if it wasn't us, then who? The Fossil guys? I don't think so! How about the gem stone people? Not a chance. If it was going to be done, it had to be done by someone within our field, so Geoff and I decided to run with it. We have always said that the party is around 2% about our Birthdays, and 98% about an excuse for meteorite people to get together and have some fun. While we like to toss in some humorous Harvey Awards at times, it really has grown into a very respected event. And this year being on the receiving end really was very special. As I write this, I am now back in the Brenham strewnfield area trying to tie up some of the loose ends. Things like dealing with poachers, doing a little more hunting before the wheat starts growing, and of course marketing the specimens we have found. Speaking of poachers, I think most of you know this, but I do want to reiterate this just to be sure: The Brenham specimen that was placed into Michael Blood's auction then had to be removed from the auction at the last second due to the fact that it was illegally poached (and the true land owner found out about it and caught the poachers before it was too late), WAS NOT one of our (Brenham Meteorite Company's) specimens! I want everyone one to know that we have legal title on ALL of our specimens. We have video footage of them coming out of the ground, usually with the land owners present in the filming of the dig. We offer Certificates of Authenticity, that establish provenance for each and every specimen. It is our intention to establish and obtain a premium on our specimens with each COA, just as receiving an ID car with a specimen from Wards, AML, or AMM adds value to those specimens. Only we hope that we don't have to be long dead for that added value to be established. :-) Rest assured that when you buy one of our specimens, you don't have to worry about an angry land owner showing up after your money is gone, demanding his specimen back! While our recovery project has garnered some great publicity due to the 1,430 pound find, there is more to come. We have hired a professional cameraman who has been recording each dig for our upcoming TV documentary. Now there are things that could go wrong and prevent the documentary from being completed, so it is not guaranteed, but it is our full intention to press through to make it a reality. This type of exposure will only help increase the value of our Brenham specimens over the Non-BMC Brenham specimens. So keep that in mind if you are shopping for Brenham in the future. We are not sure what else might get poached and brought to the market, and of course there are very legal specimens that have been found in the past. Just remember if you are considering buying a Brenham, if there isn't the BMC documentation with it, you will want to factor that into the price you are willing to spend. Right now, we are the only ones selling BMC Brenham specimens. As time passes other dealers will offer BMC Certified Brenhams. With each one expect to receive documentation of when it was found, where it was found, by whom it was found, and from which specimen it came from (if it is a slice). We give out COAs with the PURCHASERS name on the document. So if you buy one of ours from someone else, request that documentation of your purchase from them (and the COA from us to them) be included to preserve the provenance of your historical piece. A couple moments of effort now could very well add substantial value to your piece down the road. And if your piece happens to become a TV Star by showing up in the documentary or elsewhere, then you will have one more thing to brag about.
