[meteorite-list] Text vs HTML settings/ Netscape and Mozilla...
Hi Folks, In regard to the TEXT' preference as stated by Art, here's an easy to use tip for making that setting in either Netscape or Mozilla 1.0 (and Beta). I'm not certain this will work in the newer 6.0 + versions of Netscape, but it probably will. Note that I'm commenting on the email clients (Communicator, etc.) that are included with those particular browsers. When you pull up the address book in either of those browsers, double left click on a name or contact listed in the book, MeteoriteCentral, for example. When that selected window comes up, you will notice that it contains a line with a selection box that allows you to choose whichever format (text or html) that you wish to send your messages in, to that particular person. The format selection that you choose for that person's listing will only apply to that particular listing. It will not affect the formatting in any of the others. I also find in the version of Outlook Express that I have (6.00.26~) that the address book listings in it also have the 'check box' method for selecting TEXT ONLY emails. I would imagine that most, if not all, of the other versions also have this option. In that I have no other email clients, I cannot recommend a fix for them. But check their address books to see if the above provision is available in others as well.

We who are fortunate to have a fair amount of reference materials/specimens/ experience/etc., immediately recognized that the specimen was not likely meteoritic. However , if one were to consider the literature alone regarding the definitions of chondrites, I , myself, could call this a chondrite. So I can see how this rock could be easily mistaken for a meteorite on first glance. But having had a few years of experience, I thought this was a probably a sediment product; either what is essentially a concretion on the micro scale, or silica gel--(not quartz) or what I settled on is a reduction sphere*-- possibly a sulfate or carbonate akin to Alum, for example. In any case this is an interesting rock. I'd like to know how hard the pellets are and are they easily dislodged from the matrix. I suspect also that the soil is highly alkaline where this was found. If one is going to hunt for meteorites, this situation emphasises the value in putting together a small collection of micro specimens for gaining experience and having something to compare unknown specimens to. Fortunately, the availability of African meteorites make this within most budgets. Regards, Elton * Reduction Sphere: A white, leached, spheroidal mass produced in reddish or brownish sandstone by a localized reducing environment, commonly surrounding an organic nucleus or a pebble and ranging in size from poorly defined specks to a large perfectly round sphere more then 10 inches (25 cm) in diameter--McGraw-Hill Dictionary of Geology and Mineralogy pg. 237 In red-ox chemistry, reduction is a flow of molecules (electrons actually) to form new compounds. In geochemistry in this case it is a post depositional clumping of non crystaline compounds which are marginally soluible in water (hence, leeched ) in an oxygen- deprived environment. Like the mica mineral, glacounite, the molecules in solution tend to clump around detris such as fish or krill fecal pellets as they precipitate from the surface into the cold, oxygen-deprived depths. In this example the clumping occurs long after deposition in a weathering process. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list _ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] Cutting irons?
Hi Jamie What I know is that the irons will smear if you use a diamond blade (the metal smars on the blade itself and reduces the blades ability to cut. I've heard that for larger irons, they use those carbide cutoff blades, much cheaper overall than diamond and they don't get loaded up or smeared like diamond blades do. The downside is that your limited to whats avail commercially as to thickness of the blade and hense loss of material. Gravity feed will work fine for cutting most things including metal (which is the most common form of saw for cutting industrial metal). For smaller irons though, you might think about using a wire/grit saw. slower, but your material loss will be much less. This is how they cut very expensive opal for triplets and although the machines they use are really expensive, the process is simple and used in principle at many quaries for large blocks Mark - Original Message - From: Jamie Stephens [EMAIL PROTECTED] To: Meteorite-List [EMAIL PROTECTED] Sent: Sunday, January 05, 2003 9:16 AM Subject: [meteorite-list] Cutting irons?

But I'd also like to see what I can learn first-hand. (Yet another way to spend lots of time and money on meteorites.) What blades are best? I have a 12 slab saw that can accomodate 10 blades. Oil only. Are the meteorite CBN blades better than good-quality, traditional diamond blades? I'd like to use 10 blades to minimize kerf/waste, but blade strength might be an issue.

[meteorite-list] Newspaper Artcle, 06-22-1999 Mars Meteorite Life Debate
The Dallas Morning News June 22, 1999 Page: 7D By Alexandra Witze Hot rocks: Possible bacteria in 2 other meteorites stir caldron of debate about life on Mars. HOUSTON - Spring has sprung a new crop of Martian bacteria claims. NASA scientists say they've identified structures that look like fossilized bacteria in two additional Martian meteorites. Under a special microscope, the meteorites called Nakhla and Shergotty appear to contain small round and sausage-shaped structures that resemble Earth bacteria. There are some similarities here, said David McKay of NASA's Johnson Space Center in Houston. We have not proven that they are fossil bacteria, nor have we proven that they are from Mars. In 1996, Dr. McKay's team announced finding possible fossil bacteria in another Martian meteorite, ALH 84001. That claim is still controversial. If any such meteorite turns out to contain Martian bacteria, it would be science's first example of extraterrestrial life. The Nakhla and Shergotty discoveries are more tenuous than the ALH 84001 claim, Dr. McKay said last week as he presented the findings to a meeting of lunar and planetary scientists in Houston. The researchers recently split open a piece of Nakhla, a Martian meteorite that fell near that Egyptian town in 1911, killing a dog on impact. Only 13 Martian meteorites are known on Earth; they all contain the chemical compositions that are known to occur on Mars. Inside Nakhla, the scientists found tiny spheres and wormlike features, scattered across clay surfaces within the meteorite. Some of the structures appear by themselves, while in other areas they are clustered or embedded within the clay. Under an electron microscope, the structures look much like bacteria on Earth, Dr. McKay said - including some his team grew in the laboratory last year, and others found in the Jemez Springs region of New Mexico. The Nakhla bacteria are substantially bigger than those Dr. McKay' s team saw in ALH 84001. That makes the Nakhla structures a lot easier to study, and puts them more in the size range of typical Earthly bacteria, Dr. McKay said. One criticism of the ALH 84001 bacteria has been that those structures appear too small for a typical cell - and, in fact, Dr. McKay's team has since retracted that part of the claim, that the wormlike structures in ALH 84001 are truly bacteria. The NASA team thinks it can even see the Nakhla features with an ordinary microscope, as tiny flecks peppering the meteorite. Other scientists at the meeting said they would need a lot more proof to believe that the structures were actually bacteria, and that they had formed on Mars, not Earth. In another presentation, Andrew Steele of the Johnson Space Center showed pictures of Earthly bacteria and fungi, such as staphylococcus and penicillium, on the surfaces of other meteorites. Almost every meteorite is contaminated with these terrestrial organisms, he pointed out. Contamination is a serious issue from the moment a meteorite has the temerity to land on this planet, he said. Dr. Steele has found Earth fungi penetrating Nakhla, and other researchers have detected Earthly chemical traces saturating ALH 84001. Nakhla does have one thing going for it: It was picked up right after it landed on Earth and kept in strict preservation. ALH 84001 was found in 1984 in the Allen Hills region of Antarctica, where it had probably lain on the icecap for more than 10,000 years. Everett Gibson, a member of Dr. McKay's team, said the researchers took every possible precaution to get a fresh piece of Nakhla, free from contamination. Dr. Steele and Dr. McKay have joined forces to study Nakhla in more detail, with Dr. Steele assuming that the features are all terrestrial contaminants and Dr. McKay assuming they are all Martian bacteria. The two scientists will meet regularly and hope to eventually come to some agreement about what the structures actually are. Dr. McKay's team reported seeing similar, though fewer, shapes in the Shergotty meteorite. At just 165 million years old, Shergotty is the youngest of the three meteorites containing purported bacteria. ALH 84001 is more than 3 billion years old, and Nakhla 1.3 billion years old. If this proves out, this will show that life has basically spanned the entire history of Mars, said Dr. McKay. Other researchers at the meeting weren't sure that proof was forthcoming. When Dr. McKay ran over his allotted presentation time, the packed room of scientists grumbled and hissed when they weren't allowed to ask him questions because of time constraints. Aside from the new meteorite findings, many questions remain about ALH 84001. At the meeting, Kathie Thomas-Keprta of Dr. McKay's team presented more work she hoped would bolster the ALH 84001 claim. The evidence concerned grains of magnetite, a magnetic mineral found in ALH 84001 that can also be produced by bacteria on Earth. The meteorite' s magnetite is very pure and shaped in elongated prismatic crystals, just like
[meteorite-list] Newspaper Article, 01-14-1998, Minnesota Iron Meteorite Found
Minneapolis Star Tribune January 14, 1998 Page: 1A It came from outer space and filled up his pocket. A meteorite that a Champlin man dug up in his back yard appears to be part of an asteroid core, and that has made it a valuable piece of rock both. By Jim Dawson In a classic example of manna from heaven, Al Stegora of Champlin has sold a meteorite that dropped into his back yard thousands or millions of years ago to a consortium of six universities and museums for $38,000. He would have made a few thousand more if he hadn't been such a cosmic idealist. I knew this was something out of the ordinary, Stegora said of the 123-pound rock, which he found in 1983 while digging a sewer excavation in his back yard. I had a suspicion that this was something rare. Indeed. His rock was actually a chunk of metal, mostly iron and nickel, that was probably part of a distant asteroid formed billions of years ago when the solar system was born. A collision in deep space threw this piece toward Earth - and into what would become Stegora's back yard. What he didn't realize was that his rock was valuable. Scientists and private meteorite dealers would be willing to pay tens of thousands of dollars for it. The tale of Stegora's rock began when he unearthed it with a backhoe while digging for a sewer connection. The rock, about a foot long, a foot tall and 8 inches wide, came up with a scoop of sandy soil, but Stegora didn't notice it. The following year, as he was finishing the project in his yard, he came across the lumpy black rock, which weighed as much as a small adult. He lugged it over to his doorstep and left it there for five years, he said, hoping somebody would see it and tell me what it was. It was clear from its weight and the ringing sound it made when rapped with a screwdriver that it was metal. The outside was rough, scorched and melted. Butt of jokes Stegora eventually moved it into his garage to get it out of the way. It sat there for seven years and served as a curiosity and butt of jokes for friends and relatives. About a year ago a friend at work, Leo Winkleman, began urging Stegora to find out what the rock really was. All of a sudden it was time to start looking into it, Stegora said. I needed somebody who knew about iron and metal rocks. On the advice of a friend of a friend, he called Robert Pepin, University of Minnesota geophysicist and planetary scientist. Pepin, a researcher who keeps pieces of Mars and the moon in his office, was just the right scientist. He told Stegora to saw off a corner and send it to him. Two hacksaw blades later (iron meteorites are extremely hard) Stegora delivered a piece to Pepin. A quick look through a mass spectrometer revealed it was clearly a meteor, Pepin said. He sent it to the lab of John Wasson at the University of California, Los Angeles. Wasson, a professor of geochemistry, is regarded as the world's leading expert on meteorites. He told Pepin, in so many words, to grab it for museums and research. Metal asteroids such as Stegora's are vital to researchers who want to study the origins of the solar system about 5 billion years ago. The ultimate core sample Metallic meteorites are usually asteroidal cores, or the metal cores from large asteroids created in the earliest days of the solar system. And they are the only core material available, because we can't get the cores of planets or large bodies, Wasson said. His detailed tests revealed something else that scientists hadn't expected - in chemistry and composition, Stegora's rock was an exact match with a 3-pound metal meteorite dug up by a farmer 4 miles north of Anoka in 1961. It was clear, Pepin said, that Stegora's rock is a larger piece of the same meteoroid that must have broken into pieces after entered the Earth's atmosphere. The earlier, smaller find is listed as the Anoka Meteorite in meteorite catalogues. Finding two pieces like this means this is probably close to where it fell, Pepin said. There are probably tons of it scattered around out there. Meanwhile, Stegora's friend, Winkleman, had put out word of the meteorite on the Internet along with Stegora's phone number. A dealer from New York called, and sight unseen said it was worth between $25,000 and $50,000. Stegora was amazed at the amounts of money being discussed, but when he found out that the dealer would chop the rock into little pieces and sell them, he backed away from the deal. I really wanted to keep this in Minnesota, he said. One of my main concerns was that people be able to see it. I didn't want it chopped up at all. Making the deal Wasson immediately began putting together a consortium of universities and museums to buy the rock before a dealer could persuade Stegora to sell. We as scientists should do as much as we can to get material like this into museums, he said. A new iron meteorite is found about once every two years, and once you've asphalted over the countryside (with development), they will be harder to
[meteorite-list] Newspaper Article, 06-01-2000 Tagish Lake
Paper: The Toronto Star Location: Toronto, Ontario, Canada Date: June 1, 2000 Meteorite find excites scientists By Peter Calamai Yukon Fragments offer `best chance ever' to study birth of our solar system. 'This is our best chance ever to see what organic chemicals were present when the sun and planets were formed 4.5 billion years ago. It was likely a small asteroid that once . . . had water.' Michael Zolensky NASA cosmic mineralogist SCIENCE REPORTER OTTAWA - Traces of the chemical building blocks of the solar system - and of the human race itself - may well be preserved inside hundreds of pieces of a rare meteorite recovered recently from the ice surface of a Yukon lake. The Tagish Lake meteorite is the largest meteorite fall in Canada and the pieces are the least contaminated of any meteorite ever recovered anywhere in the world. ``This is our best chance ever to see what organic chemicals were present when the sun and planets were formed 4.5 billion years ago, '' said Michael Zolensky, a cosmic mineralogist with the National Aeronautics and Space Administration. While the meteorite's outer layers reached white hot temperature as the fireball flashed through the atmosphere on Jan. 18, the inside would have remained cold, preserving any delicate organic molecules trapped there. Some of those molecules were captured from the swirling gas cloud that later became our solar system, scientists said. Zolensky joined researchers from the University of Calgary and the University of Western Ontario at a news conference in Calgary yesterday to explain the significance of the find. Initial lab tests of tiny samples reveal the meteorite contains water and is of a type called a carbonaceous chondrite, with 50 times as much carbon as the much more common stony meteorites. The previous carbonaceous chondrite was recovered 31 years ago. ``This is the scientific equivalent of a NASA sample return mission to an asteroid using a satellite that would have cost $100 million, '' said Peter Brown, a meteor researcher at the University of Western Ontario. The meteorite fragments look like burnt charcoal briquettes and easily break apart because of the high carbon content. Satellite photos that captured the path of the Yukon fireball plus eyewitness accounts allowed researchers to calculate that the meteorite came from an asteroid once in orbit between Mars and Jupiter. ``It was likely a small asteroid that once reached at least room temperature, had water and a higher organic content than the earth, '' said NASA's Zolensky. Forty grams of recovered meteorite will be parcelled out to researchers around the world and scientific probing of the rocks could last for years. But there is more of the meteorite to go around because of a race against time that swelled the find from an initial one kilogram of rock to at least six kilograms and maybe as much as 10. Meteorite searchers rushed to recover the fragments before spring weather melted the ice covering Tagish Lake between Atlin in northern B.C. and Carcross in the Yukon. On a first visit in February they tried using RCMP sniffer dogs, but the animals had been trained for different smells. Then the searchers looked for spots where wolves had urinated because past meteorite fragments attracted such behaviour. In the end the team of a half-dozen searchers had to come back April 20 when most of the snow covering the lake was gone. By May 8, when the ice on Tagish Lake was declared unsafe, searchers had noted about 500 spots where meteorites had bored into the ice and retrieved roughly 200 fragments. Most meteorites that crash into Earth are contaminated by landing in soil or quickly lose the rarer organic chemicals as gases in the warmer conditions here. But the Tagish Lake meteorite avoided these dangers because it landed on ice that kept it frozen and largely pristine. ``Of all the times I dreamed of finding meteorites, I could never have dreamed of finding anything like this,'' said an ecstatic Alan Hildebrand, a planetary scientist at the University of Calgary. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] etched Molong
Hi folks ! Just want to let you see what I got when I etched my piece of Molong on last week. Today I took my piece out of the Isoporopyl. I etched it using Jim Hartman's method with ferric chloride. The result is very nice - who else has tried to etch Molong or has an etched piece ? Have a look at: www.austromet.com/MolongA.jpg - looks like one of the german comic-stars from Fix und Foxi www.austromet.com/MolongB.jpg - has also an interesting pattern The piece is 15 x 11 mm.

Re: [meteorite-list] Tektite collecting?
Hi, Tom, List member Norm Lehrman's website, The Tektite Source, is not only a great place to look for tektites (so much cooler than walking the Nullabor Plain!), it is also a great place to learn about tektites and see some really fine examples: http://tektitesource.com/ Of course, everybody's idea of the ideal collection is different. My collection is about 25% tektites, but then I'm a tektite nut. First qualification for inclusion in a meteorite collection: they fell from the sky. Oddly enough, while both meteorites and tektites, as a field of study, enter the scientific literature in the 1790's, after two centuries, we can say much less with certainty about tektites than we can about meteorites. And they also pass the fundamental test of collectability: they are cool... or neat.. or intriguing... or a puzzle, or whatever slang you want to apply to that intangible something that makes us collect.

I have pieces of Aouelloul gras on my web site if any one is interested in a piece. It is funny that tektites came up today. My daughter wasn't feeling well today so I lay down with her for a while and fell asleep. Dreamed someone was asking me if something was a tektite or not. Piece had a flat polished face that was interesting looking. I told them there was one way to check and be sure and I was reaching for the propane torch to see if it foamed when the phone rang and woke me up. Dang now I will never know if it was a tektite for sure. ;-) This list appears to have invaded my subconcious.
