[meteorite-list] moon glass
hi list and moon-atics, its 'understood' that dhofar 081/280 are paired, probley, well wash. univ. in st. louis web site on dhofar 081/280 says 081 doesn't have sphere glass but 280's matrix is glass rich, hummm i think i found a sphere of white-milky glass 1/2mm in my 280, but i'm not trained to detect such things read that titanium in moon glass is green with 1% ti yellow with 2 to 13% ti red with 14% ti does not cover my white sphere unless white is zero percent? happy collecting temp. lunatic david __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Renaissance Wax Polish
Bill: I don't have any experience with Renaissance wax, but I have used regular paraffin wax on my Nantan and Campo and it has significantly reduced the oxidation. First melt the wax, then put the meteorite into it, completely submerged, for one half hour. Remove it and lay it on a paper towel to dry and cool. No need to remove any excessive wax - there shouldn't be any. I coated my Nantan about three months ago and it still looks great. Same for my Campo.

[meteorite-list] Renaissance Wax Polish
Renaissance Wax is used by museums to protect valuable metals. It is also used by knife collectors to keep the metal in knives from rusting. Does anyone have any experience using this wax on iron meteorites? Bill Russell __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list

But it does include all the other Hot Desert meteorites like DaG's, HaH's etc. Cheers, Bernd ** End of Original Message *** Hello Bernd and Walter, I would assume the "skew toward the lower grades" that Walter mentioned is the result of - the more a meteorite is weathered - the more it looks like a terrestrial rock - the the harder it would be to recognize it - the FEWER there will be found. But, here is a better reason - Since the weathering grade is based upon the interior condition of a stony meteorite, the high percentage of the total of meteorites that come from DRY (Hot & Cold) Deserts will drive this "skew toward the lower grades". Once again, the weathering grade is irregardless of the condition of the exterior of a meteorite. Maybe this is a good opportunity to review how weathering grade is determined (for the recent collector or for those new to the List): Weathering Grade (Wlotzka, 1993) W0-no visible oxidation of metal or sulfide but a limonitic staining may be noticeable in transmitted light. Fresh falls are usually of this grade, although some are already W1. W1-minor oxide rims around metal and troilite and minor oxide veins. W2-moderate oxidation of metal, about 20-60% being affected. W3-heavy oxidation of metal and troilite, 60-95% being replaced. W4-complete (>95%) oxidation of metal and troilite, but no alteration of silicates. W5-beginning alteration of mafic silicates, mainly along cracks. W6-massive replacement of silicates by clay minerals and oxides. __ Do You Yahoo!?

[meteorite-list] lunar
hi list, this week i had lunar on the brain, i ordered and received from labenne brothers a 0.056 gram dhofar 280 lunar anorthositic highland breccia.as a produce clerk this seems to be the biggest boulder i can afford.on the net i found out several things about the lunar area. the apollo missions brought back many rocks of largely 2 types basalts and breccias, but also a few special finds including white crystaline anorthosite and impact melts. just a few samples of really upper mantle rock. i viewed pictures of lunar meteorite slabs and noticed the highland ones were black/gray and found out made of around 80% black anorthosite type rock, why then is the highlands look white from the earth?the moon surface must reflect alot of light? happy collecting david __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] Miracles
A couple of my meteorites had started to get kind of rusty and I was afraid that a couple others may share the same fate so I sent them off to Jim Hartman a couple weeks ago and got them back today. My Fredericksburgh was almost totally covered with rust and is completely free now. Apparently, Jim also has a healing touch with stones too! My 20g Juancheng individual wasn't collected right away and so had begun to weather some plus living in such a humid enviroment didn't help it either. After getting it back from Jim if it wasn't the same shape I would swear it was a different meteorite that had just fallen this afternoon. Thanks for saving my pieces Jim. I'm sure my Eagle Station and Losttown will be nice and safe for years to come now.

Hello Listees, Listoids, In the July 2002 issue of Sky and Telescope (p. 58), you'll find a review of O.R. Norton's "Cambridge Encyclopedia of Meteorites". I don't quite agree with J.K. Beatty's final conclusion: "the neophyte meteoriticist would have an easier time digesting Harry McSween's 'Meteorites and Their Parent Planets' " but that is a matter of taste.

[meteorite-list] NASA Ames To Host 'Magnetite On Mars' Meeting
Kathleen Burton May 31, 2002 NASA Ames Research Center, Moffett Field, Calif. Phone: 650/604-1731 or 604-9000 E-mail: [EMAIL PROTECTED] RELEASE: 02-68AR NOTE TO EDITORS AND NEWS DIRECTORS: You are invited to attend the "Magnetite on Mars" meeting on June 4 and 5, to be held in the Space Sciences Auditorium, Building N245, at NASA Ames Research Center. Research experts from around the world will gather to discuss whether the magnetite, a mineral common to both Earth and Mars, is of biological or non-biological origin in the Mars meteorite ALH84001. To reach Ames, take the Moffett Field exit off Highway 101 and drive east to the main gate. Members of the news media must present a driver's license or valid government-issued photo I.D. and press credentials at the NASA Ames main gate, where they will be issued a visitor badge and directed to Building N245. All foreign news media must have clearance prior to the meeting, bring a passport and press credentials, and will be escorted at all times. NASA AMES TO HOST 'MAGNETITE ON MARS' MEETING Researchers from around the world will convene at a 'Magnetite on Mars' meeting on June 4 and 5 to review recent findings that support or refute the biological origin of magnetite crystals in the ALH84001 Mars meteorite. The meeting will be held in the Space Sciences Auditorium, Building N245, at NASA Ames Research Center in California's Silicon Valley. Scientists will examine the potential consequences of magnetic bacteria on early Mars and consider whether the magnetic environment necessary for the existence of the magnetite mineral was present on Mars 3.9 billion years ago. They also will discuss whether magnetite's presence on early Mars can give us important clues about the planet's current environment. Scientists from the United States, Canada, Japan, Germany and Spain will present more than 20 papers during 20-minute talks. "We have to go beyond the current controversy over whether the magnetite in the Mars meteorite is of biological or non-biological origin, and consider what the implications are if the hypothesis is true," said conference organizer Dr. Chris McKay of NASA Ames. "If it is true, the implications are that we may have to readjust the chronology of early life on Mars and even redesign future Mars missions." The June 4 session begins at 8:15 a.m. PDT. Session I, chaired by McKay, will discuss: "Is the magnetite of non-biological or biological origin?" Session II, which begins at 2 p.m. PDT, will discuss "Does magnetite on Earth provide insight into the biogenic magnetite on Mars?" and is chaired by Dr. Ken Nealson of the Jet Propulsion Laboratory, Pasadena, Calif., and the University of Southern California. Session II, titled "Could magnetotaxis have developed on Mars?" begins at 9 a.m. PDT on June 5 and is chaired by Dr. Richard Frankel of the California Polytechnic State University, San Luis Obispo, Calif. Magnetotaxis is the orientation of magnetic bacteria along a magnetic heading, like a compass. There will be a media interview opportunity from noon to 12:45 p.m. PDT on June 5 in Conference Room 141 in Building 245, featuring McKay, Nealson, Dr. David McKay of NASA Johnson Space Center, Dr. Imre Friedmann of Ames, Dr. Joseph Kirschvink of the California Institute of Technology, and others. Between 2 p.m. and 4 p.m. PDT, a closing panel will sum up the workshop findings. A meeting agenda is posted on the Internet at: http://amesnews.arc.nasa.gov/pages/pubnot.html Media representatives planning to attend should pre-register by contacting Kathleen Burton in the NASA Ames Media and Community Relations Office. NASA Ames is the agency's lead center for astrobiology, the search for the origin, evolution, distribution and future of life in the universe, and the location of the central offices of the NASA Astrobiology Institute, an international research consortium.

The largest piece recovered so far weighs 38.4 gr (Raukas et al., 1999). VESKI S. et al. (2001) Ecological catastrophe in connection with the impact of the Kaali Meteorite about 800-400 BC on the island of Saaremaa, Estonia (MAPS 36-10, 2001 pp. 1367-1375, excerpt): About 800-400 B.C. a meteoroid hit a then relatively densely populated island, forming the Kaali meteorite impact craters. Unfortunately the people living at that time on the island of Saaremaa were illiterate and we have no direct written record of the impact event. Indirect written historical records interpreted as describing the Kaali meteorite blast event come from Tacitus (1942) and Pytheas from Massalia.
