[meteorite-list] Tsavorites
Hello Charles list, I too am interested in learning more about these mystery-shrouded Tsavorites that are being compared to andassociated with Moldavites. By being mined from deep in the earth, man-made glass can be ruled-out as a verdictregarding what they are. You refer to them as glassy mineral stones andyes they do make better cut gem stones than true Moldavite but somebody somewhere must have figured out whether this is indeed a newly discovered variety of tektite or a non-impact related gem or mineral. Hopefully others on this list may be able to shed a little more light onTsavorites or pass-along a few pearls of wisdom on the general topic. Some scientific testing of Tsavorite material needs to be conducted. Plenty of people would be eager to know the results. Szep, over out... - Original Message - From: Charles R.

Re: [meteorite-list] Tsavorites
Hello, all, well, Tsavorite is a rare green member of the garnet-group, and at least that is the fact, these have nothing to do with Tsavorites. Moldavite is a name for bohemian green tektites, so they are not these eather. So the queston is, are they Tekties or something others. I have had some raw pieces of this material, and at least the pieces I had, had not any special characters of tektites. These are usually dumbled or cutted pieces, so without the more wide lab tests its impossible to say anything sure about the origin. To me they look just green obsidian. When I see the first with typical characters of tektite, I may change my mind...;- The arears, they have been found have / have had quite a lot volcanic activity, but not anything (yet), which tells about the impactite structures, and so it looks to me much more possible, they are just volcanic origin glass, and have nothing to do with impacts. But who knows... One way to check the origin is to buy some and get them analyzed in some university lab, but I belive, it would be a waste of time and money. Anyway, if someone is selling tektites, the seller is in response about the origin. This far I have not seen any serious data about this offered by the the sellers. take care, pekka Robert Szep wrote: Hello Charles list, I too am interested in learning more about these mystery-shrouded Tsavorites that are being compared to andassociated with Moldavites.

[meteorite-list] Meteorite Hits House In Louisiana
http://www.nola.com/news/t-p/index.ssf?/base/news-0/106464393133640.xml HEAVENLY HOME WRECKER Uptown resident finds his roof, floors ripped through by fallen rock; Tulane scientists say tests indicate rare, otherworldy object: a meteorite By Mark Schleifstein The Times-Picayune (Louisiana) September 27, 2003 When Roy Fausset walked into his Joseph Street home after work Tuesday evening, he knew immediately that something was very, very wrong. The powder room door was open and it looked like an artillery shell had hit the room, he said. Something had fallen with enough force to punch a hole through the roof and two floors before coming to rest in the crawl space beneath the house. It was a sandy-colored rock that appeared to have been burned around its edges. Preliminary tests by scientists at Tulane University indicate this particular rock came from outer space. If so, that makes it an exceedingly rare phenomenon. Meteorites enter the Earth's gravitational field with some frequency; all but a tiny percent of them burn up during their passage through the atmosphere -- what are commonly called shooting stars. So far as could be determined, the Joseph Street landing was a first for the city. We found olivine, pyroxene, plagioclase and troilite, a combination of minerals often found in meteorites, said Stephen Nelson, chairman of Tulane's earth and environmental sciences department. Nelson used X-ray diffraction Friday afternoon to double-check the type of individual minerals that make up the rock. He had first identified the rock as rhyolite, a form of volcanic rock found in Mexico and south Texas. The minerals Nelson found don't automatically mean it's a meteorite, he said, because they're also found in the Earth's mantle, deep underneath the planet's crust. But we don't commonly see pieces of mantle falling out of the sky, he said. And the black crust, which I thought was a weathering line at first, perhaps it's a fusion crust -- material that melted as it passed through the atmosphere. Nelson said the rock is known as a stony meteorite, a type more common than the black, ironlike rocks that have become the archetypal meteorites in the public imagination. Fausset said neighbors told him they heard what sounded like a car crash just after 4 p.m., but they didn't know it was his home being hit. One of my neighbors on South Tonti Street had two children in her back yard, eating Popsicles, and they heard a terrific noise, he said. And a lady next door to her heard it. She was indoors and ran out into her back yard, but didn't see anything. But if it had hit 100 feet away in that back yard, it could have killed one or all of those people, Fausset said. Finding the damage inside his home came as a shock, he said: We had just renovated the powder room and now there was plaster everywhere. I looked up at the ceiling and saw this big hole. A quick check in the adjoining utility room revealed another hole in the ceiling and what looked like a broken ceiling joist. I went outside and looked up and about midway down the front of the roof, there was a hole about the size of a basketball, he said. Fausset immediately called his insurance agent, who suggested he check upstairs to look for any more damage. In his daughter's second-floor room, Fausset discovered that something had smashed through the ceiling there, too, and it had demolished an antique wicker desk before cutting a neat hole in the wall-to-wall carpet and the flooring beneath it. Back in the first-floor bathroom, Fausset found another hole leading through the floor to the crawl space. That's when I called the police, he said. When officers arrived, they found several chunks of rock beneath the hole in the bottom floor that matched fragments found in Fausset's daughter's room. I'm in shock, Fausset said Friday after learning the rock had been identified as a meteorite. Oh, that's scary. I will certainly go to church this Sunday, because the Lord was certainly sending me a message. And the meteorite? I guess I'll go put it in my safe-deposit box, or just frame it, he said. . . . . . . .

Hi Charlie and List, That's a nice, informative page on Tsavorites: It's interesting to notice that they come in different colours: pink, brown, orange, yellow, besides the perhaps more familiar, pretty green. Also, check on Tsavorite's refractive index, as well as it's dispersion value - as against that of Emeralds. I think that there is no connection between Tektites and Tsavorites. Perhaps the confusion might have started by some now so well informed gemstone dealers? Thanks Charlie for the interesting link.

[meteorite-list] Missouri Meteorite Strike Zone Pinpointed In Research
http://www.news-leader.com/today/0927-Meteorites-176462.html Meteorite strike zone pinpointed in research A grant for more extensive drilling could bolster extinction theory. Mike Penprase News-Leader (Springfield, Missouri) September 27, 2003 Osceola - They never knew what hit them. Denizens of the shallow sea covering much of Missouri more than 300 million years ago were slammed by a meteorite 1,200 feet across and moving five times faster than a bullet, leaving a geological puzzle to solve in what is now St. Clair and Hickory counties, Kevin Evans said Friday as he and more than 100 fellow geologists and students searched for signs of that mighty collision. In a bit of poetic justice, ocean dwellers called blastoids got blasted into extinction, joked one member of what was described as the largest field trip ever held by the Association of Missouri Geologists. But Evans was serious about the implications of the research, bolstering extinction theories based on meteorite strikes and letting astronomers know what a strike from a small meteorite might do. We think we've got something kind of interesting here, Evans said of what is called the Weau-bleau-Osceola Structure. Rock formations thousands drive past every day on Missouri 13 and Missouri 82 got a going-over from hammer-wielding field-trip participants, who were attending the association's 50th annual meeting in Springfield. Sites on the highways and at an Ash Grove Aggregate quarry drew superlatives from the geologists as Evans recounted how he and fellow researchers discovered what may be the concentric rings of uplifted rock signifying what could be one of the largest meteorite strike zones in the United States. It will make a good story, Evans said, perhaps good enough to lure outside help. The next step in the project is to try for a National Science Foundation grant to finance further research, he said while the clink of hammers against rock echoed at the quarry. The story began when Evans used computer software to join four maps together and discovered the ring formations around Weaubleau Creek. The research team theorizes the meteor strike created a crater 12 miles wide and more than 1,000 feet deep at ground zero. It would have dwarfed a nuclear bomb blast, Evans said. Some of the evidence is just south of the quarry, where researchers point out signs that the area was one of several strike zones along the 38th Parallel, running from Kansas to Illinois. Twisted and mixed formations of what should have been neatly horizontal layers of sedimentary rock may support the belief that something big hit the Ozarks millions of years before dinosaurs were on the scene. While the Missouri Department of Transportation has helped the team by drilling three test holes in July along Missouri 13, a grant would enable the team to do more extensive drilling, along with other research, Evans said. It could take years to gather enough evidence to make an airtight conclusion, Evans said, but the rewards were immediate for students like Scott Sowers. A road cut on Missouri 82 swarmed over by the geologists surrendered a prize for the SMS student: an Osceola round rock or Weaubleau egg, a spherical stone so common it can be found in the walls of stone structures in the area. They're evidence a meteorite hit, turning rock into liquid that cooled as airborne spheres before falling back to Earth, the researchers contend. This is my first rock of the day, and I'm excited about it, Sowers said of the softball-size stone. Other students gathered discs from prehistoric plants called crinoids and others hacked rocks to get pieces of iron pyrite. Most of them also gathered up bits of breccia, speckled rock consisting of sharp bits of hard rock embedded in softer rock such as sandstone. That rock and quartz, which tests show were shattered by an immense force, are other bits of evidence the SMS team uses to advance its theory, contending a meteorite strike was so violent it shattered rock into tiny bits, embedding them in what eventually turned to stone. Retired geologist and ground zero resident Gordon Kinney said he was excited, too. Until he read about the SMS team's theory, he had no idea he was living on a cliff that's part of a meteorite strike zone. I thought, holy cow, we're right the middle of it, he said. He tried to determine whether there was anything unusual about the area he lives in years ago, but wasn't able to find precise enough maps to draw a conclusion, Kinney said. I don't think there was any clue, he said. Retired geology professor Dick Gentile said he doesn't believe there are any clues supporting the SMS team's theory. At one point, he seemed to try to generate a debate at the quarry with Evans and fellow researcher Chuck Rovey. That's just part of the scientific method in which evidence supports theories, except that there's rarely enough evidence to turn a theory

Re: [meteorite-list] Tsavorites
Tsavorites are also closely akin to another kind of grossular garnet, the famous demantoid. A good demantoid will have more fire than a diamond, and be a bright green. I agree with the assessment of someone getting their signals crossed; if these stones are tsavorite, they have nothing to do with tektites. If they are tektites, then calling them tsavorite is a big misnomer. Never the twain shall meet!

Re: [meteorite-list] Tsavorites
Hello, "Tsavorite" is named after the Tsavo National Park and this name should be used only with these kenyan green ones. The group-name "Grossular" is named after R. Grossularia, the botanical name of the gooseberry, because of the resemblance of the color (pale green) to that of the plant. Green grossular-garnets can be found also from other areas, but only kenyan ones can me called as Tsavorites, others are just green grossular garnets. Also other colours of grossulars should be called with their colour + grossular; pink grossular garnet etc... best rgds, pekka s Jose Campos wrote: Hi Charlie and List,That's a nice, informative page on Tsavorites: It's interesting to noticethat they come in different colours: pink, brown, orange, yellow, besidesthe perhaps more familiar, pretty green.

Re: [meteorite-list] Tsavorites
Hello, all, The hardness of obsidian or volcanic glass is 5 - 5, moldavites 5. Dispersion of obsidian is 0,010 and moldavite doesnt have it at all. The difference is not enough to make a valid classificaton with this way. The refractive index is 1.48 - 1.50 for both, so the refractometer is useless in this problem. Also both are amorphics. In fact also Moldavite + other tektites are glass, Si02 + AL2O3, so its very, very difficult to find the difference from dumbled or cutted pieces. Usually raw Moldavite has clear characters, typical for it, and so do also the other tektites. Any african ones I have seen, dont have this typical appearance. Absorbtion for green obsidian is 680, 670, 660, 650, 635, 595, 555, 500 . With Moldavite, usually the absorbtion cant be ordered. If someone on the list happens to have this material and a spectrometre nearby, it would be nice to hear the results about the absortion-spectre of the material. I gave specimens I had, to my friend, who is a gemmologist, FGA. Will call her, and ask her to check the spectrum, if she still have the pieces left. It may take some days, but will let you know the results.

http://www.thestatesman.net/page.news.php?clid=1theme=usrsess=1id=23876 Meteorite shoots across Orissa sky The Statesman (India) September 27, 2003 BHUBANESWAR - A huge meteorite shot across the sky this evening causing panic in coastal Orissa particularly Kendrapara, Jagatsinghpur, Bhadrak and Jajpur. Villagers saw a huge ball of fire falling from the sky. For a few seconds, it appeared to be daylight. District officials received frantic messages and in some villages like Mendhakia and Kandia, the fire brigade was mobilised on information that the ball of fire had landed and caused considerable damage. Three people were admitted to hospital at Kendrapara after they fell unconscious on seeing the meteorite Along National Highway No. 5 drivers said they were dazzled for a few seconds. False alarms were raised in almost every coastal district after 6.30 p.m. when it was first seen in the sky. Hundreds of people rushed out to cross check. Some said they could hear a rumbling sound while others vouched for the fact that the windows and glass panes had rattled. Phones kept ringing as people from distant places wanted to ascertain facts and the well being of their relatives living elsewhere in coastal districts. When contacted sources at the planetarium here said it was a huge meteorite which was visible across the coastal belt. It is different from the meteor shower which is small in size and can be predicted, Dr Jayadeb Kar of the planetarium here said. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Great Meteorite Collections
All, I am looking for information on exceptional, world-class meteorite collections in the U.S. that are WEST of the Mississippi. I know of course about the American Museum of Natural History and the Field Museum, but what about in the western states? I am more interested in Public collections, although information on private collections would also be helpful. - Bob Martino, Tucson, AZ Can you really name a star?

[meteorite-list] NP Article, 12-1950 Meteorite Crater Found in Canada
Title: Reno Gazette City: Reno, Nevada Date: Monday, December 18, 1950 Page: 4 Meteorite Crater? Stories of Skies By Hugh Pruett Astronomre, Extension Division, Oregon Higher Education System Huge depressions surrounded by high rims of broken rock and situated on toehrwise level plains have been found in several places on the earth. In recent times it seems certain that these have been blasted out by the descent of stony or metallic missles from the great interplanetary spaces. The best known of about a dozen such holes is the famous Barringer Meteorite crater in Arizona, an almost circular depression approxiately 4000 feet across. The top of the rim varies from 120 to 160 feet above the surrounding plain and the inside floor is about 600 feet below the rim. Terrific upheaval of the original strata occurred at the time of impact for huge boulders, some as large as an ordinary house, make up a considerable part of the rim. In the rim and scattered for miles on the plain, tons of metallic meteorites have been found. Now we learn of another crater, recently discovered in the northwestern part of Quebec south of Baffin Island, which dwarfs considerably the Arizona depression. It is about 2 1/2 miles across from rim to rim, and the top of the rim stands 550 feet above the plain. Unlike the Arizona crater, this latest depression contains a lake, the surface of which is somewhat higher thant he surfaces of the numerous small lakes found int eh surrounding plain. Last July when it was first examined by a scientific expedition, the water surface in places was by ice three feet thick. It is said that this crater, which is located in an unfrequented part of the world, was first noted on aerial photographs by a prospector, Fred W. Chubb. This was reported to the Globe-Telegram of Toronto. This paper was instrumental in organizing a scientific expedition, which included Dr. V. Ben Meen of the Royal Ontario museum. Although no meteorites have been found among the boulders of rim or on the surrounding plain during the short preliminary investigation, Dr. Meen feels quite certain the formation is due to the action of a huge meteorite and is not volcanic in nature. He believes the tearing fromt he plain of liely ten billion of tons of granite which forms the rim, took place sometime between 1000 and 3000 B.C. Further study is planned next summer when magnetic methods will be used to try to locate meteoritical material and to determine of a large mass is likely beneath the lake. The scientists are sure no glacial action has taken place since the crater was formed. The explorers hoped they were the first campers ever in that locality, but the finding of a tin can blasted their hopes. One member in anger threw it away. Later when they wanted to see if it contain a message, they could not find it. Excellent pictures of the crater and the exploring party are carried in the October number of Griffith Observer published in Los Angeles. Time for Aug. 14 and other publications discussed the subject.Please visit, www.MeteoriteArticles.com, a free on-line archive of meteor and meteorite articles.
Re: Fw: [meteorite-list] Green Glassy Stone
Robert and List, There should be no confusion between Tsavorite Garnet and Natural Glass the color of Tsavorite! I have sold both Tsavorite and Tektites for many years and have not had to explain the difference to anyone. I have had to convince some people that the litttle emerald looking stones are garnet rather than emerald and I haven't had any of the Tsavorite Colored natural glass to sell, only the other types of tektites that we are all familiar with. My point was that this ebay seller only used the word Tsavorite to describe the color of what he is selling and went on to say that they weren't Tsavorite Garnets. Perhaps he should just say GREEN and not use a word that could confuse a novice. As you noted, magnification will reveal bubbles in the glass but not the garnet. Also, if you perform a simple hardness test on the rough material you could distinguish the two. You probably wouldn't want to use that test with a faceted stone as a scratch would mar the surface. So, let's know (on the list at least) that Tsavorite refers to a certain green grossular garnet but that the same color might appear in a tektite or other natural glass. Some people might describe some pieces of Libyan Desert Glass as Amber (the color) but that doesn't make it Amber (the resin gemstone). Robert, your points are all valid but I don't see any confusion between green garnet and green glass.Maybe a person who knows absolutely nothing about minerals could have some trouble, but the ill-informed should make some effort to learn a little about stones before they start buying them, and yes, we do bear some responsibility in helping them to learn.

There are Tsavorite GARNETS and what are called Tsavorites which are being referred to as tektites. Both are found in the same region but are two different things. The Garnet formed inmatrix and has a crystaline structure. The green glassy stones do not display any crystal-structure and do not appear to have formed within any type of matrix. One ebay seller specifically mentions that he is selling Tsavorite Tektite which is not to be mistaken for Tsavorite Garnet. The common naming and coloration shared by both materials creates confusion between the two. One of these two types of similar things contain tiny air-bubbles... Guess which one... it's not the Garnet... R.

He only uses this term to describe theCOLOR of the stone he is selling. He even goes on to say that Tsavorite is a green garnet, which is correct. He does however call the stone a tektite. Perhaps someone can clarify the truth or non-truth of this proclamation. My best, Thomas H. Webb Do you Yahoo!?The New Yahoo! Shopping - with improved product search Do you Yahoo!? The New Yahoo!

[meteorite-list] Re:Great Meteorite Collections
Hello Bob, The Denver Museum of Nature and Science (I liked the former name much better, the Denver Museum of Natural History) has a wonderful collection of meteorites, many collected by H. H. Nininger when he had a close relationship with the Denver Museum. That said, forget about the fine collection of meteorites. Drawers full reside upstairs where only staff and the volunteers of the Denver Meteorite Posse (a group of volunteers started by Jack Murphy to hunt down meteorites in Colorado) have access, or had access, as the curator of minerals (which includes meteorites) has been laid off from his job of over 30 years. Jack Murphy, Curator of Minerals, has given a good part of his life to the Denver Museum, only to be laid off along with 10 or 11 other staff members. Other museum staff have resigned in outrage over the layoffs. Volunteers are TICKED OFF! Once again, meteorites get shoved way down the list of museum items to show the public, far behind fossils, stuffed animals and minerals. However, there is one large iron meteorite that children can touch in the new space display. One. No mineral curator, no meteorite display to speak of. This stinks. Regards, Fred Hall / Meteorhall
[meteorite-list] Ball of Fire From Sky Sparks Panic In India
http://www.deccanherald.com/deccanherald/sep28/i5.asp A ball of fire from sky sparks panic DH News Service September 27, 2003 BHUBANESWAR - Panic gripped many north and coastal Orissa districts this evening after people witnessed a huge ball of fire falling from the sky. Two houses were reportedly gutted in north Orissa's Mayurbhanj district as parts of the fireball fell on them. There were no reports of anybody being injured. In many areas in north and coastal Orissa districts such as Kendrapara and Cuttack people came out of their houses as a burning meteoroid-like object dazzled the sky. The light was so bright that it looked like day time, said an eyewitness in Baripada. The whole sky remained illuminated for a few minutes, said a resident of Cuttack city. At several places in Jagatsinghpur and Kendrapara district, people heard a loud bang along with the bright light. An unconfirmed report said a stone with magnetic power was found on the rooftop of a house in Jagatsinghpur town soon after the fireball crossed the area. Residents in many parts of Bhubaneswar also saw the fireball in the sky. People from different parts of the city including journalists rushed to Sahid Nagar area of the capital after rumours did the rounds that parts of the burning flying object had fallen in the backyard of a private residence. Policemen who rushed to the spot cordoned off the area. However, the object turned out to be parts of a remote control plane used by NCC cadets which had fallen nearly 15 minutes before the fire ball appeared in the sky. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
