Lengthy caveat: I believe I told some folks from Wisconsin there weren't any volcanoes near there but, some recent rock hound reports have claimed to have found Lava. Be it remembered that the northern Midwest USA and Southern Canada were scraped flat several times over, any above ground basal/ash was sent south. Any ash was mixed in with the prairie loess and could have been mistaken for ash from the Great Western Basin such as was deposited in the Dakota Badlands. So the object in question is not likely native to the FWD Metroplex. You asked any suggestions? have a lab look at it at this point. One final caution.. To my further recall, the nickel test kits widely available via ebay can render a false positive in the presence of iron so its utility in testing for meteorities is possibly unreliable Elton __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Meteor crater?
Thanks Ron. I never read any books on Meteor Crater, Az. with any sort of useful, scientifically oriented to meteoritics type information. It's always, Barringer bought it, tried drilling for the mother load of Nickek-Iron, failed, it's 30-50,000yrs. old stuff and that's it. Any ideas where i can get more information like your post . You know Tom Knudson is the one who really wants to go there and, well, give it a shot at finding a chunk of Canyon Diablo, poking its nose out of the dusty desert terrain to take home . Hey, I bought a 6pound Canyon Diablo individual 10 yrs. ago from Bob Haag . It has lots of character- meaning it's not a 6lb. round boring slug of iron. If you bought it to slice it up, it does'nt matter what the shape is, but for my first meteorite at $80.00lb. back then and going for $500.00lb. now with some dealers, it was a great investment that promisses to skyrocket in the near future.

Re: [meteorite-list] Vesta meteorite???
Thanks Ron!!! do you have the information of all this asteroids?? I would like to have this information, thanks a lot like orbit, names, spectra etc I have a couple of references which I'll send along. Here's one: Drake MJ: The eucrite/Vesta story METEORITICS PLANETARY SCIENCE 36 (4): 501-513 APR 2001 Many lines of evidence indicate that meteorites are derived from the asteroid belt but, in general, identifying any meteorite class with a particular asteroid has been problematical. One exception is asteroid 4 Vesta, where a strong case can be made that it is the ultimate source of the howardite-eucrite-diogenite (HED) family of basaltic achondrites. Visible and near-infrared reflectance spectra first suggested a connection between Vesta and the basaltic achondrites. Experimental petrology demonstrated that the eucrites (the relatively unaltered and unmixed basaltic achondrites) were the product of approximately a 10% melt. Studies of siderophile element partitioning suggested that this melt was the residue of an asteroidal-scale magma ocean. Mass balance considerations point to a parent body that had its surface excavated, but remains intact. Modem telescopic spectroscopy has identified kilometer-scale Vestoids between Vesta and the 3:1 orbit-orbit resonance with Jupiter. Dynamical simulations of impact into Vesta demonstrate the plausibility of ejecting relatively unshocked material at velocities consistent with these astronomical observations. Hubble Space Telescope images show a 460 km diameter impact basin at the south pole of Vesta. It seems that nature has provided multiple free sample return missions to a unique asteroid. Major challenges are to establish the geologic context of the HED meteorites on the surface of Vesta and to connect the remaining meteorites to specific asteroids.

CONTACT: Don Savage NASA Headquarters, Washington, DC (Phone: 202-358-1547) Tammy Jones Goddard Space Flight Center, Greenbelt, MD (Phone: 301-286-5566) Ray Villard Space Telescope Science Institute (Phone: 410-338-4514) PRESS RELEASE NO.: STScI-PR95-20 ASTEROID OR MINI-PLANET? HUBBLE MAPS THE ANCIENT SURFACE OF VESTA NASA's Hubble Space Telescope images of the asteroid Vesta are providing astronomers with a glimpse of the oldest terrain ever seen in the solar system and a peek into a broken off section of the mini-planet that exposes its interior. Hubble's pictures provide the best view yet of Vesta's complex surface, with a geology similar to that of terrestrial worlds such as Earth or Mars. The asteroid's ancient surface, battered by collisions eons ago, allows astronomers to peer below the asteroid's crust and into the past. Astronomers also believe that fragments gouged out of Vesta during ancient collisions have fallen to Earth as meteorites, making Vesta only the fourth solar system object, other than Earth, the Moon and Mars, where scientists have a confirmed laboratory sample. (About 50-60 other meteorite types are suspected to have come from asteroids, but positive identifications are more difficult to make.) The Hubble observations show that Vesta is far more interesting than simply a chunk of rock in space as most asteroids are, said Ben Zellner of Georgia Southern University. This qualifies Vesta as the 'sixth' terrestrial planet. No bigger than the state of Arizona, Vesta offers new clues to the origin of the solar system and the interior makeup of the rocky planets. Vesta has survived essentially intact since the formation of the planets, Zellner said. It provides a record of the long and complex evolution of our solar system. Resolving features down to 50 miles across, Hubble reveals a surprisingly diverse world with an exposed mantle, ancient lava flows and impact basins. Though only 325 miles (525 kilometers) across, it once had a molten interior. This contradicts conventional ideas that asteroids essentially are cold, rocky fragments left behind from the early days of planetary formation. Besides providing scientists with direct samples, Vesta's chipped surface allows Hubble to study the asteroid's rocky mantle, giving scientists a unique opportunity to see what a planet looks like below the crust. Our knowledge of the interior composition of the other terrestrial worlds, the Moon, Mars, Venus, Mercury and even Earth, depends heavily on theory and inference, Zellner said. Vesta allows us to actually see the mantle and study pristine samples in our laboratories. Before these observations, only the smaller and less geologically diverse asteroids, Ida and Gaspra, have been observed in detail by the Jupiter-bound Galileo spacecraft. Unlike Vesta, these smaller objects are pieces torn off larger bodies by collisions that occurred perhaps only a few hundred million years ago. * * * * * The Space Telescope Science Institute is operated by the Association of Universities for Research in Astronomy, Inc.

HUBBLE MAPS THE ANCIENT SURFACE OF VESTA VESTA: THE SIXTH TERRESTRIAL PLANET? Vesta is the most geologically diverse of the large asteroids and the only known one with distinctive light and dark areas -- much like the face of our Moon. Previous ground-based spectroscopy of Vesta indicates regions that are basaltic, which means lava flows once occurred on its surface. This is surprising evidence that the asteroid once had a molten interior, like Earth does. One possibility is that Vesta agglomerated from smaller material that includes radioactive debris (such as the the isotope Aluminum-26) that was incorporated into the core. This radioactive shrapnel probably came from a nearby supernova explosion. (In fact a supernova might have triggered the birth of our solar system.) This hot isotope may have melted the core, causing the asteroid to

[meteorite-list] Mars Global Surveyor Images - November 20-26, 2003
MARS GLOBAL SURVEYOR IMAGES November 20-26, 2003 The following new images taken by the Mars Orbiter Camera (MOC) on the Mars Global Surveyor spacecraft are now available: o Rocks Exposed on Slope in Aram Chaos (Released 20 November 2003) http://www.msss.com/mars_images/moc/2003/11/20/index.html o Cracked South Polar Plain (Released 21 November 2003) http://www.msss.com/mars_images/moc/2003/11/21/index.html o Crater Cluster Near Pathfinder (Released 22 November 2003) http://www.msss.com/mars_images/moc/2003/11/22/index.html This October 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a large cluster of small craters located northeast of the Mars Pathfinder landing site, on the plains scoured by the old Ares and Tiu Valles outflow channels. Clusters of craters such as these usually form as secondary impacts. Secondary impacts are the result of a larger, single meteor, asteroid, or cometary impact---the impact ejects debris that falls elsewhere and creates smaller, secondary craters. In other words, the material that hit the ground to form these craters did not come from space, it came from Mars. The craters are located near 19.9°N, 33.3°W. The image shows an area 3 km (1.9 mi) wide, and is illuminated by sunlight from the lower left. o Iberus Vallis Troughs (Released 23 November 2003) http://www.msss.com/mars_images/moc/2003/11/23/index.html o Multiple-Event Gully (Released 24 November 2003) http://www.msss.com/mars_images/moc/2003/11/24/index.html o Layers in Crater Wall (Released 25 November 2003) http://www.msss.com/mars_images/moc/2003/11/25/index.html This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows layers exposed in the upper wall of a meteor impact crater, and the dry talus that has been shed from this layered slope. This September 2003 image is located near 30.2°N, 272.8°W. The image covers an area 3 km (1.9 mi) wide, and is illuminated by sunlight from the lower left. o Elysium Mons Wind Streak (Released 26 November 2003) http://www.msss.com/mars_images/moc/2003/11/26/index.html All of the Mars Global Surveyor images are archived here: http://www.msss.com/mars_images/moc/index.html Mars Global Surveyor was launched in November 1996 and has been in Mars orbit since September 1997. It began its primary mapping mission on March 8, 1999. Mars Global Surveyor is the first mission in a long-term program of Mars exploration known as the Mars Surveyor Program that is managed by JPL for NASA's Office of Space Science, Washington, DC. Malin Space Science Systems (MSSS) and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA.

Dear Adam, and List, I am not a geologist, but I have seen samples of rainbow pyrite.

In Wisconsin, the given rule for any kind of federal or state grant money for housing, is that families with children 6 Years old and under have to have homes tested for LEAD in the painted surfaces, as they are most susceptible to fatal lead-poisoning, not so with adults. As everyone knows, lead is very soft metal, easily meltable, and very HEAVY in weight. Anyone having one of these WOW Meteorites, should have it checked for lead, and thats how we close him down, if I'm right. Even though he warns about kids under 7, he is still selling a product that could potentially kill or make a small child who handles, or God forbid, puts it in it's mouth at high risk! Knowingly using lead in this manner would probably be a criminal offence. Don't think E-bay wants a piece of that action!!!

[meteorite-list] Moon Laser Base Proposed for Asteroid-Comet Hazard
http://www.space.com/astronotes/astronotes.html Moon Laser Base Proposed for Asteroid-Comet Hazard Leonard David space.com November 25, 2003 A lunar facility to mitigate the asteroid-comet hazard for the Earth has been proposed by Russian scientist, Viacheslav Ivashkin of the M.V. Keldysh Institute of Applied Mathematics. The idea was tabled this week at the International Lunar Exploration Working Group (ILEWG) meeting on the Kohala Coast, Hawai'i. The base would be multi-tasked in its operation. Solar energy would first be collected at the facility, then converted into electricity to power both an astronomical observatory and a laser station. Ivashkin's proposal has the observatory scanning the heavens for any near-Earth objects (NEOs) -- either comets or asteroids -- that could be on an incoming trajectory harmful to Earth. In this case, the laser station is proposed to give a powerful laser effect on that object to deflect or destroy it, Ivashkin reports. The Russian scientist has assessed the amount of solar collecting hardware needed to be planted on the Moon to thwart hazardous NEOS, as well as laser power levels required to produce the desired effects of mitigating troublesome comets or asteroids. In a paper presented at the ILEWG, Ivashkin concluded that international cooperation in designing, creating and operating the energy-astronomical-laser space base on the Moon is necessary. Ivashkin's study of the asteroid-comet mitigation concept is being supported by the Russian Foundation for the Basic Studies and the Harbin Institute of Technology, China. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Possible poisonous Lead Alert!
Dear List, Upon further reflection after writtting an answer Wed. Nov.26,2003 ,post to Adam, on-list, about my suspicions that Galaxy Meteorites need to be tested for lead content and how I came to this conclusion, I'd ike to add a warning and take it a step further..hopefully, but doubtfully, I'm wrong. To all on listgetting rid of this person from E-bay is important, but what about all and any of his merchandice which has already been sold to non-member (IMCA) public? Possibly , people who may not take the storing and air-tight displaying methods we do, or may just add it to their neat collection of rocks, on their dresser ,accessible to little brother or sister ? A letter to him, informing him that we might be on to him, might make him pull his meteorite line off e-bay, but considering the health risk to any already sold, If I'm right, there's not only a monetary loss to buyers, but a danger alert that should go out publically somehow. Don't give him a chance to disappear, without e-bay taking some public responsibility, or if neccessary the law being involved. Hope I'm wrong,about the lead.

Re: [meteorite-list] nantan
Roman and others, This guy has it backwards. Selling a tektite as a Nantan makes no sense. You should always sell true tektites with a descriptive type name like Indochinites, and on occasion sell the Nantans as tektites...not the other way around. Selling a Nantan as a Nantan is a real loser these days...at least call it a meteorwrong like Hematite to get a decent buck or two($). Telling them it's going to the good of the IMCA also helps I hear. ;) gobble, gobble John John Yeseree, it's a teardrop shape INDOCHINITE.

[meteorite-list] Workshop on Chondrites and the Protoplanetary Disk
http://www.lpi.usra.edu/meetings/chondrites2004/ Chondrites and the Protoplanetary Disk November 8-11, 2004 Kauai, Hawaii MEETING LOCATION AND DATE The Workshop on Chondrites and the Protoplanetary Disk will be held November 8-11, 2004, at the Radisson Kaua`i Beach Resort Hotel, 4331 Kaua`i Beach Drive, Lihue, Hawai`i (888-805-3843, www.radissonkauai.com). PURPOSE AND SCOPE The goal of this interdisciplinary conference is to understand how components in primitive chondrites and interplanetary dust particles were formed and thermally processed in the protoplanetary disk by comparing cosmochemical constraints with astronomical observations of young stellar objects, protostellar disks, and astrophysical models for thermal processing of dust by shock waves, disk winds, and asteroidal collisions. The workshop will review the major advances since the 1994 meeting on Chondrules and the Protoplanetary Disk in characterizing and understanding the isotopic, mineralogical, and chemical compositions of chondritic components in diverse kinds of primitive chondrites, constraining their ages and thermal histories, and developing models for their origin and accretion into chondritic planetesimals. This four-day meeting will focus on understanding the high-temperature processes that formed chondrules, Ca-Al-rich inclusions, amoeboid olivine aggregates, and components in chondritic matrices and interplanetary dust particles and will attempt to relate these to the processes responsible for the formation and evolution of the protoplanetary disk and disks around young stars. __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Moon Laser Base Proposed for Asteroid-Comet Hazard
Hi, I would suggest to Dr. Ivashkin that more than international cooperation is necessary before some nation or nations build a laser powerful enough to destroy a small planetoid and place it on the Moon only 400,000 kilometers away, with full access to the entire surface of the Earth and everyone on it. It would take a remarkable degree of trust. A level of trust, in fact, that is difficult to imagine given the present status and inclinations of the upstart monkeyboy civilization achieved to date by homo sapiens. I'm betting that Tom's goony Martians wouldn't like it much either... Sterling K.
